I bought my first Boss 429 in April 1070, four months after I got home from Vietnam. I had seen a picture of one in one of the magazines and really liked the looks of that car. My first car was a 1964 Plymouth Savoy with a 426 wedge and a four speed. I was a Mopar guy unitl that Boss came out. I, like several other people, had problems with my engine thanks to a Ford dealer installing the 1970 solid lifter cam. There are four oil control plugs in the block that need to be changed when going from hydraulic to solid lifters and that wasn't done with my engine. After two years of getting jerked around on getting the engine fixed right, I took it out to Jack Roush in Livonia, Michigan in 1972. That car was no slouch when I first got it but boy did he wake it up. He turned my engine into a 460 using my rods and the pistons from a T series engine plus a 460 crank. I brought a Crane .600 lift 318 degree duration cam and lifters plus an Accel distributor. He supplied a dual quad intake with two 600 Holleys and titanium intake valves. He estimated the horsepower at between 525 and 575 and there was no doubt in my mind when I stuck a leg in both carburetors the first time. It got up to 7500 rpm's in a heartbeat and it had more to go but I didn't. I still have that car. I bought two others in the meantime which I ended up selling because I couldn't afford to get them restored properly. One of them owns the record for the highest price ever paid for a Boss 429 Mustang when it sold for $605,000 in January 2007 ($550,00 plus 10% to Barrett-Jackson). It was lot #1325 if you want to look it up. It's also listed under the 10 highest prices ever paid for a Mustang at auction. Wish I still had that car. Ed Meyer of Indiana had that car looking like brand new. All three of my Bosses were Candy Apple red and they were all 1969's. That dual quad intake that Jack Roush sold me is reportedly one of only 25 made by Ford. Maybe having the engine built lessened the value of the car but I would never put it back to stock. That car is my pride and joy.
My older brother had to sell his 69 Boss 429 for $5,500 back in the early 80's to help pay for medical school. My father hated that car and couldn't see any value in it. Even then my older brother and I knew it would be worth a fortune in the future. My father was so cheap that pennies would squeal when he spent them. My father drove a 60's something VW bug the first year that had a gas gauge. Never washed or waxed that bug. Had Earl Scheib paint that piece of crap bug and it got stolen a week later.
I am a die-hard Mopar guy , and this is an interesting video. I like reading through the comments sections. Best thing to do is not be biased too much. Any intelligent person knows, that a handful of money and knowledge can put most engines at serious competition with each other. Back in the 70s we didn't have a lot of money, so we stuck to the simple go fast changes. Camshaft, lifters, better valve springs and retainers, rear end gears, shift kits in the transmission, stall speed converters, and headers. For us Mopar 6-pack guys, the Performance Kit to change the springs in the vacuum end carburetors was also a must. Other guys might opt for Progressive linkage. Ford guys had plenty of opportunity, and any Mopar guy that had a first look at some of the performance heads that Ford produced got their eyes opened. Ford was no slouch. The street engine Ford Boss 429 had to be mild enough to drive. And that was it's choking point. Make no mistake about it though, this is a great platform that just needed some performance goodies like most any other car manufacturer regular production engines. It's really at all about what you personally like oh, but at the end of the day they are hunks of Steel, Cast iron, and various other metals that make up an engine with a different manufacturers badge on it. hail to all of my Gearhead Brothers out there. I sure miss the 70s, when things were more laid back, cool music, and our world wasn't wound so damn tight
Amen to all of that! I too am a Mopar man at heart.. my first car was a 70 Duster 340... It was fun picking on the 5.0 mustangs back in the day! I have come to believe that all of the makes have their strong points and weakness. It took a well tuned Hemi to outrun a 440-6 on the street.. I have always been told I have an old soul... I'm 41 btw please Subscribe and I will have plenty of good content coming your way! Andy
@@UnityMotorSportsGarage true statement on the 440 + 6. I have owned those and the small block six pack engines. For their time, pretty impressive. Too many people like to compare half a century ago technology to today's modern fuel-injected engines and suspension on the cars which is completely pointless. Apples to Apples yes but never anything else LOL
@@UnityMotorSportsGarage you gotta be kidding me...had a 89 Notch 5.0, ex patrol car w headers and shifter, I'd smoke that crappy 340 as I did with Corvettes until about C5 came out
I love mine, goes like hell, has no traction to speak of. But so much fun to drive. Will it beat the 69 Charger, no, but the Charger has 650 hp and 530 cubes, so it’s a tossup , love em both. Let’s go disturb the peace.😂😂🤪
@@UnityMotorSportsGarage Yeah I will Andy. How about doing a video on how NASCAR lost its way and starting racing these tube frame cars with fake bodies - rather than real modified stock cars you could buy at your dealer. IMO Bill Elliots #9 Thunderbird was the last real "stock" car. A story on that car would be great too. Take care my man.
@@DennisMerwood-xk8wp remember watching Awesome Bill from Dawsonville with my dad. That old Thunderbird was giving them the blues back in the day. Every time he won they were trying to his dissect car. Also, NASCAR has never been the same since they left the Winston Cup. Wife and I probably watched for another year or so after Earnhardt died. They got to changing the point system so much it just wasn't NASCAR anymore.
@@DvlDawg DviDawg, I stopped watching it at about the same time you did. They turned the greatest auto racing show on earth into a farce. Bill Elliott set the fastest lap in NASCAR history, running 212.809 mph at Talladega Superspeedway on April 30, 1987. At Daytona the following July, all cars were equipped with restrictor plates to limit horsepower. I watched for about another year and finally gave up in disgust. Have not watched a race since. Take care my man. Stay safe.
I love every engine, no matter the manufacturer, that started with a 42... but that Boss 429 Mustang, especially the 1969 model with the four headlights, is my absolute favorite
David you are right, The big 3 had some amazing engines back then! Thanks for Watching and please subscribe as I have some really good content coming up!
Well, with that much iron in the nose handling was an after thought . If you ran them in the city, double digit gas mileage was just an occasion for celebration.
Thanks for using the Schartman Boss Cougar picture. We have had that car since spring of 1974. Today totally restored and raceable. Have played with a few Boss cars. Doug Herzog
Right now, If you can afford it, you can buy a 760 HP Shelby Cobra, or a 797 HP Hellcat Charger. Both would stomp those 60's tanks in every way, shape, and form. There has never been faster, or more powerful American muscle. Ever. And this is it. EV is around the corner.
@@deborahchesser7375 No doubt, but EV that is NOT absolutely loaded with tech, that goes 0-60 in less than two seconds, and costs 50-70 thousand dollars is really a better, more practical application. When EV is out of the price range for 3/4 of the population, it only serves the rich.
@@jamesgeorge4874 I had a 69 Mustang with a 427 ( yes it was a orig 428CJ car ) that ran 13:10 with a single traction and motor only, was one of the fastest cars around back then...Now the new Mustangs run High 11's and then you can drive them on a 500 mile road trip.
@@markcatcash4688 I currently have a Fox body Mustang that will run 11.70, is 100% streetable, it scales at 2475 lbs, and has an aluminum 5.3 with a sloppy stage 2 cam, and springs. But you can go buy a Hellcat, bolt on slicks, and beat my mustang, no problem. The point is, America has a horsepower war where you can go to any big 3 dealer, and buy a 600-800 horsepower car, off the showroom floor, NOTHING from the 60's 70's etc. even comes close. You could pit the new Toyota Yaris GR against your big block Mustang, it would beat it, with a 1.5 litre 3 cylinder. Just sayin.
I was only able to attend one NASCAR race in person. It was at the Michigan International Speedway, in 1976. The late great David Pearson won it driving the famous #21 Mercury with the Boss 429, for the legendary Wood brothers team! Watching him coming down the front stretch while leading the race,the sound of that Boss 429 had a distinctive sound all it's own! He dominated & won the race. I'm 68 now & I still watch the races on TV, but it's nothing like being there in person, but a helluva lot cheaper! ❤🏁🏆
my only nascar race was michigan, 98. we were in turn 3 about 1/2 way up the stands. it totally sucked. the cars seemed to take forever to get back to us = vroom past us, then i would go make a sandwich, and then a 3 second vroom past us. the only good thing about that day, getting to see Dale3 race
Would you believe that the 428 Cobra Jet and Boss 429 are basically the same engine? Also both Hemi, and designed, built and manufactured by Ford before they sold the manufacturing rights to Dodge after they lost a class action lawsuit with the federal government over misleading the public on the true horsepower and torque. The 428 Cobra Jet is what got them in trouble, and after the lawsuit and settlement with all families involved Ford changed the name of the engine because it had been outlawed to ever be a production engine and so was born the Boss 429 and Dodge came with the 426 Hemi and the cops couldn't catch them either and because Ford was the original offending party the Federal government demanded that they gain an edge over both of these engines and so was born the 429 Interceptor. True story.
Untold story though. When the Boss 429 came about in 69, there was only one true Ford engine builder. Holman Moody...The same engine builders that made the 427 FE the cornerstone of NASCAR... Either you used their engines or parts or you were just riding around the track... Notice when the Boss 429 came out in NASCAR, there was no 5 year delay on rising to the top... H/M knew their crap...
@Steve Gregg true! You have to remember that Jon Kasse got his start by being Dyno Don's crewman then Allen Root did a ton of work on the BOSS head that Glidden ended up running! It was actually offered in the Ford SVO catalog until Glidden had them remove it... Glidden was a very sharp man who knew how to win no matter of the combination! He won championships with Cleveland power, Mopar W2 headed small block, and The BOSS... One fact little known is he built a Chevy Monza to run at Indy in protest of NHRA adding weight to his combo... He didn't do well with it but he did race a Chevy for one race! Andy
Good job, Andy. The real savior of the Boss 429 in drag racing was Alan Root, who's design update ( given a Ford P/N) addressed some of the original Boss head shortcomings. This basic redesign, tweaked by Kaase, Roush, Glidden, Leonard and others, powered those 1980's IHRA and NHRA Pro Stock cars to such dominance.
Long live the internal combustion engine and the boss 429 what a beast. I had the pleasure of riding in a mustang boss 429 when I was a kid and what a beast it was. 💪🏻💪🏻💪🏻
AMEN LONG LIVE THE I.C.E.,NOW WE'VE GOT THESE "HIPPIE TREE HUGGERS" CRYING "OH NO YOU HAVE TO GO ALL ELECTRIC/HYBRID ETC/EITHER OR NOW IF/WHEN THEY TRY TO CONVERT US TO RUNNING PROPANE I'M GIVING UP ON LIFE 😠🙄😤🤬👎👎..!!
I'd literally give my left nut to ride in a '70 boss 429 (one of my dream cars the other is a '67 shelby gt500) which I know for a fact I'll never get my hands on a running '70 boss 429 since their getting rarer and rarer by the day ERRGH 😠🙄😤🤬👎👎..!!
I had a 1969 Boss 429 in stock form, my 440+6 cuda would blow it off the road easily! then i bought a 1970 Boss 429 that had been worked a little......Holman and Moddy solid lifter cam, dual blueprinted holleys on a medium riser intake, headman 180 degree headers,, scatter shield and McLeod clutch.........OMG that was a tire boiling bad ass! the power from 3000 rpm and up was unreal that car would "relight" the rear tires at 45-50 mph going into 3rd gear!
That is good stuff right there! Thanks for Watching and please Subscribe as I have some cool stuff coming up! Check out my project MIXED UP BOSS.. I'm putting BOSS 429 Style heads on a 429" Stroker Windsor! Andy
@@douglasadams6024 Amazing, thanks for sharing. I'm currently putting together a 72' Challenger with a 500hp 340, and it's getting a set of custom built 180 degree headers. Will make a video when it's done. Happy Motoring!
My brother had a stock SS 396 Chevelle in 1981 that was practically wore out smoked and everything but that dang car would spin the tires going into 3rd with the automatic trans at 70 mph, stock street tires of course but still blow my mind lol!😎👍
When I was a kid and just learning about cars my uncle helped a friend of his swap the intake on his Boss9 he tracked on the weekends. To this day I swear my uncle was able to stick a beer can in the intake ports and not hit the sides, I'm probably mixing up my memories but I remember they were huge. It took a few years to really appreciate that I got to work on such an engine. Great video!
The 428 SCJ cars were amazing!!! Severely underrated from Ford.. Thank you for watching! Please Subscribe and check out my project MIXED UP BOSS.. Andy
Did you know that just about all 427 Cobra roadsters sold to the public weren't even 427s.......they were pumped up 428s. The 427 FE side oilers were put into the 427 Cobra S/C model. Shelby thought the bigger cost of the 427 over the 428 would hurt the car for homologation. However, if a customer found out he had a 428 and bitched about it, Shelby would supply the 427 to him.
Thanks for the video! Back in the early- mid 70’s I drove a warmed over 1970 Mach 1 with the 351 Windsor. Of course as a young blue oval gear head I lusted after the Boss 9. It was the holy grail car for Ford guys (the SOHC was so rare it wasn’t really thought about). I saw one at the drag strip around 1974 and it actually ran pretty strong. As I recall it ran about a 12.1 with headers, cam, better carb (Holley 3bbl) and slicks. That was actually really impressive back then for a street car. You are totally on point about the engines issues. With the humongous intake ports it was designed to make tons of power way up high in the RPM range when coupled with the right cam and carb. The problem was (per Jon Kaase) that the 429 ci was just too small to create enough pull through those massive ports. As you pointed out a better cam and carb helped up top, but only so much. They still were really sluggish in the low to mid RPM range. Reducing the intake ports via epoxy actually makes the engine run way better all around. The only way to make the as cast heads really work is to add ci. A LOT of ci, like way over 500. Regardless when a blue oval gear head like me sees those Boss 9 valve covers under the hood I hear the angels singing. I guess it’s similar to how MOPAR lovers feel about the Hemi!
Thanks for your input and for watching!! Please subscribe as im building a engine called MIXED UP BOSS. Im putting BOSS 429 style heads (Hammerhead Performance) on a 429" Windsor block! Thanks again, Andy
Sounds really cool. Taking the Clevor concept to a whole new new level! I’ll check it out for sure. Who makes a Boss 9 style head that will mate up to the Windsor?
@@danmyers9372 Yeah, Hammerhead Cylinder Heads, Guy that doing these heads for SBF worked with Jon Kaase for years, So he definitely knows what he's doing, Jon Kaase is the Best BBF guy around.
I'm hoping that when we Dyno this engine, Greg can make it up for the day! Thanks for Watching and please Subscribe to see how it all turns out... Andy
Bob Glidden and Jack Roush were my inspirations in the day. The final picture reminded me of my car when it had the tunnel ram sticking through the hood with the holleys topped with velocity stacks. My engine was a 302 tho. The Boss 429 was only a dream. The Mustang with any of the Boss engines would be tops.
Liked the video. I'm mostly a GM guy, but not a "only like this brand and all others stink" guy. Agree with the part at the end that the Boss was one of the best-looking engines. It's bad-ass looking, for sure. And also agree about its checkered race history. It really just didn't do that well overall, until it was made with big cubes....and even then, it was spotty. Ford fans will point to Glidden....and that's true. But it was Glidden that made the Boss, not the other way around. No other Ford team was really even particularly competitive in the same time frame, that was all Bob Glidden then. He was ahead of the curve for a few years. With the aftermarket today, you can make anything run however you want it to. But I love hearing about back in the day, when racers had to run the best they could find from factory parts and they couldn't just order up a CNC set of whatever size heads they wanted to along with an unbreakable rotating assy. Well done!
Thanks for the kind words! I'm not only this brand all other stink! I have Built Fords, Mopars, Chevys and even AMC's.. They all have their strong points and weaknesses.. Now days the aftermarket has solved many of the problems. Please Subscribe as I have other history videos that will be mixed in with my regular content! Andy
Nobody was better than Bob and Etta. Bob made magic with his intakes. Remember the guardrail wreck at Atlanta when he took off his firesuit jacket to cover the intake before the camera crew got there?
Back in the 70s, a friend of mine, who was a racer, had a few of these engines in his garage, brand new and still in the factory crates. If only I would have known what they would be worth today. Thanks for the history.
The 351C was called a "Baby Boss" so I understand the 429. They both had canted valves, huge ports and used the same spark plugs. The 351C even had a bigger (780cfm) carb! Great video!
I liked all of THEM, BECAUSE I LEAVED IN THAT AIR AMC390,, MOPAR 383, 318SLANT SIX,,FORD 289,351BIG AND SMALL,400,428,429,CHEVY 396THE REST I BLUE UP BUT 400YZBLOCK RAM AIR FIVE MOTER FASTES CAR WAS A 350PONTIACA
I have a friend who is building a 67' Fairlane with a Boss 520 in it. Chuck Lawrence, who was an engine builder for Kasse, built the engine with parts he got from John. On the dyno, the engine had an 1100 Dominator on it, and it was starving for fuel. It turned 820 hp and I think it was 785 torque. When it goes in the car, they will put a double Sniper system on it which should get it to 900 hp.
@raginroadrunner read the NHRA rules! The Ford big block isn't legal in ProStock. The rules are completely based off of the GM Big Block bore spacing Andy
Hey Andy thanks for history lesson,being in aus and no internet those days didnt know what went on,been watching some of Bob Glidden races,he sure knew how build a motor and race them
I know a couple guys out of Yucaipa that had a machine shop...DODD & SPILLMAN...Well one of them had a 429 in his truck....008 clearances on pistons.. ha...he said it didn't run right until it got good and HOT...YOUR VIDEO MAKES FANTASTIC SENSE...BECAUSE ITS TRUE TO THE BONE...TY...And I would love to have one of those 427 SOHC ENGINES IN ANYTHING....DANG GOOD BRUDDAH!!!!!
When I was a teen I had a Ford Motorsport catalogue from the 80s (I was fixing up a Mustang at the time, and was working on the engine). And all the motors and parts were Boss 429. There was a large selection of heads. I was just building a daily driver small block. But it was interesting what you could order straight from Ford, in an era when factor V8s didn't even have 200 hp.
You people that seem to be unaware that the METHOD of rating of max horsepower of an engine Changed Radically after 1970/1971, are not very smart. The industry just made up false ratings to fool the buying public.Plain and simple, just Lie about it, and foolish people will believe the lies.
Kinda like Mopar's Direct-Connection. They had a book on how to 'build' the engine with the over the counterparts. ie. W2 heads, I put a 360 in a 79 D50, that's weight was 3029 lbs with the small block. 10.09 in 1985.
6:00 mark - The factory ram air was very restrictive, but was required in certain classes. It was competing in a class of Hemi's that came factory equipped with dual quads. In Stock type racing it was a 11- second car. I recently posted a story on this. In 1970 Kar Kraft offered a kit that included jets and other stuff to make it 0.20 faster then a 1970 SCJ. Great Video!
We built those engines at the Lima Engine Plant. I drove many pistons in the Blue Crescent engine (our code name) for the 429 boss. We were also making the 429/460 regular engines with wedge heads. Some of those went into the Super Cobras. We made some 460's for the presidential motorcade. The 429 boss didn't have a head gasket, O rings around the cylinders and neoprene rings around water ports, etc. Valves were ,010 bigger that the Chrysler Hemi and the intake/exhaust ports were huge, heads were aluminum. Each rocker arm had it's own pedestal and run on needle bearings. I saw several running on the dynos at the plant......one at 5000 rpm for many ? hours just to see what would give up. I believe some went almost 24 hours. Exhausts would be glowing............!
That is amazing! They are something to see forsure... Thank you for sharing this! Thanks for Watching and please Subscribe as I'm putting BOSS 429 style heads on a 429" stroker Windsor.. called MIXED UP BOSS Andy
I cleared some land for a man back in 2008 he gave me a 1969 Ford short bed pickup truck,has a T code boss 429 in it,but he had it rebuilt with modern part's, And it pushes this old truck pretty darn good, especially at higher RPM I can see why it wasn't good for dragging but all in all for a solid street legal hot rod it's a beast

Back in 1969 of all magazines that actually tested bone stock cars the 1969 Boss 429 T was number 2 of fastest cars. Getting beat by only the ‘69 GTX 426 Hemi Auto with a 4.10 gear. Very close the 426 went 13.32 @ 107 vs Boss 9 at 13.34 @ 107. Bigger carb on boss with better exhaust and they ran very well. I owned a 1 of 6 1967 Mercury Capri R code (427 8v) 4 spd and it was no doubt quicker than my friends 1967 Hemi GTX. I did add a limited slip diff to the 3.89 gear. Ford refused to put locking or limited slip rears in the 427 comets or Fairlane’s for “safety” so any magazine article from back then was with a open diff. Crazy really but one still ran a 13.51 @ 108 with open diff.
My Uncle had a boss 429 he ran at Atlanta motor speedway in the road racing track. He dominated with it. It might not have been a good drag racer but it was a great engine for the nasser and road racing tracks.
In the Mustang, the Boss 429 was choked by restrictive intake & massively choked exhaust.I do love you mentioned the 427 sohc(cammer) The cammer was never approved because Chevy found out about it & fought it's approval with all sanctioning bodies...this also is what got The Hemi banned.
Helped a buddy put headers on his 70 Boss 429, we had to go up 6 jet sizes to get it to run right again. The speed shop was amazed that it took that much.
I was a weekender at Sunshine drag strip in Florida. I had my S code prepared by Speed Specialties of St. Petersberg. With cutouts under the doors, I ran "A" stock and did very well with the Bow Tie guys. It ran quicker than the stock SS 396's at that time in 1970.
In my Car Show years.. production assistant.. I went to many a Show.. Only Once Good Guys Show in the San Francisco area.. Seen Boss Stang on the road to the show Highway driving.. then found him.. Man oh Man.. up close it's Crazy looking.. this was about 12 years ago now.. hope he's still driving it.. but you know the price on these has Gone up.. to say the least.. Great Post UNITY..
You should see what cars show up at Ford Carlisle in PA once....... Seen many a rare Ford/Merc/Lincolns there over the years.A few I remember seeing in 2012 was Fast Eddie Schartman's Pro Stock '70 Boss 9 Cougar (1 of 2), Dyno Don's Pinto,Hayden Profitt's AFX Comet, 1 of 1 '67 Shelby GT500 428 convert.Back in the early 90's ('91? '92?) I was able to park my '64 Fairlane 500 sedan beside a couple orig. Tbolts,and chat with a old man for a few hours that had his '63 K code since new,the Fairlane was the theme that year. There's a 427 SOHC Tbucket and a Boss 9 Mustang or two that come to the local shows now and again that we enter.
@@rider660r that's Badass.. like I said.. the old job was car shows, it's always cool to see folks driving them.. Bugs on the Head lights.. especially on Hot Rods.. 👍😉
growing up I knew the greatest car geek ever, he was a school teacher in metal trades, and always at auto shop across hall, he helped kids stay out of trouble & helped them focus toward cars, trucks, metal work, yes helped me from being a dropout & who knows what. he gave his life toward helping kids, and never had wife or family, died alone in nursing home a few years ago. no idea what happened to his cars. he lived in rural VA. anyway he owned a 1969 & 1970 Boss 429 Mustangs, I know he had a few 427 SOHC powered vehicles, 1 was a drag race only mustang, and a few spare engines, a couple Torino super cobrajet drag packs, 69& 70? or 68 & 69? 1 was automatic, which I helped build in classes, 1 was 4 speed. a radical 78 king cobra Mustang II, yeah I know, but for a daily driver with .700 lift cam in a small block, it was radical, he had a totally bad ass pickup for a more fun daily driver with a tunnel rammed dual carb 429, all those in the mid to late 1980's

Absolutely great video sir, from the words to vintage clips to photographs, all add up to a Ford lovers dream. Thanks for putting it together, I will forward it to my dad!!!!
This was a great time. 1969/1970 I had more fun than I should have been legally allowed to have. Loved these big motors. Eventhough you measured fuel economy in feet not miles. Good video.
I was fortunate enough to attend the U S NATIONALS,many years in a row. Watching all those different Ford racers, from Stock to Pro Stock & all the other different classes in between! There was one man that raced in an Stock class with a 352! I didn't remember the NHRA banning "Ohio George" mustangs, powered by his revolutionary, turbocharged Boss 429's. I do remember watching him race in them! Great memories I'll remember for the rest of my life!
Yeah Ohio George with that combo pretty much killed the class he was running and NHRA banned the Turbo combo... Which is sad considering how far ahead of his time he was... Look at where Turbo technology is today... Crazy power levels.. I wish I could have a time machine to go back and watch the US Nationals back in the late 60's to early 70's...

I in January of 69 ,. I was at North Western Ford, Milwaukee WI. I saw a 69 plan Jane while Sport Roof Mustang, It had the Boss 429 stuffed into it!!! WOW I was so impressed, I was home from Nam less than a month
Way back as a teen I was a passenger in a boss 429 a church member and a 69 hemi road runner, my chevron boss son. I love Ford but was brutal in 4 shift, banging & lifting the stang. But didn't feel the speed. But the hemi. It's was a special edition was just one one long lift and we were 60-70'area. The close I felt that again was in a Yamaha GS 1,000 the first model 11 s bike. The second gear pull 20-70 was like 2-3 second. There is a difference from brute torque power. Than on the cam or live nitro power that can't be beat. Torque is fun & show & noise. LOL. His hemi was all black with back 50s on center lines beautiful car. It's has to be around. And the cam hooker sound was perfect.
Great video, thanks! I'm a Mopar guy and I know the 426 Hemi is a legend but it has a lot of shortcomings as well. But it worked great back in the day. The Boss 429 seems similar to the Ram Air V Pontiac engine. It had the same problems and was treated the same by racers during that era. I mean everything from ports that were too big to flow well at low lifts/rpms to rotating assemblies that were so heavy they became their own worst enemies.
Im a Mopar man at heart.. my first car was a '70 Duster with a built 340.. Please Subscribe as I'm working on a 426 Hemi Video right now.. Thanks for Watching! Andy
Andy you did a fantastic job on this video I love it I remember seeing the Boss 429 in the Glidden cars that the Easter run in up for the Winter Nationals in the World Finals at Pomona . The Boss 429 is the best engine Ford ever built .
YT algorythems sent me here and for once I'm glad. This was really well done! I'm a old guy and really enjoyed the history. I can't wait to start seeing videos about Ford's new 7.3 Godzilla gas engine. They lost me some time back with all those "mod" motors, but now looks like they got a winner. They've already been modifing it to over 750+ HP!

@@UnityMotorSportsGarage You're welcome! I've seen those stroker kits for the 351W but the rod angle ratio at 428-429ci seemed a little too severe for me. Sidewall loading would be pretty high.
I'm not a fan of Ford's "mod" engines either. Don't like their small 3.93 inch bore spacing. I think 3.7 inches is the maximum diameter bore that's possible.
My father worked for Ford in the 50's and 60's as VP of the Truck Div., then left and bought up several Ford, Mercury, Lincoln dealerships throughout the mid-west to revive, we also got the exclusive Shelby Cobra and de Tomasso Pantera franchises for all of the midwest (his factory connections paid off) because he sponsored Cobra Racing. He ordered me a custom 1970 Mustang "Boss", but instead of a 302 ci V8, mine came with a 351ci "Cleveland" "Semi-Hemi Head" V8 and dual Quads, and factory pipe headers. Because it (with the 351 Cleveland, built on the Ford Small Block) was so light, it was FASTER than the 428 Boss, and I clobbered every Hemo Dodge and Chevy 427 a the drag strip. The 351ci Cleveland Semi-Hemi was a far better engine than the 429 Boss or the 427 "Cammer".
I am not a Ford guy but I just love the 429 boss Mustang. I saw it in a magazine round 1970 as a kid. When I get rich I going to buy a matching nummer car.
The BOSS 429 has been a dream car for MANY folks.. I decided that I wanted to build my own version of a BOSS 429 which led to Project MIXED UP BOSS!

When I was an 11 year old kid, a used car dealer that was a member of our church, pulled into the parking lot right before Sunday evening services. I ran over to his Mustang and asked "Wow Ed is this a Boss 302"? He says- "Nah, those are fer girls. This thang's a Boss 429". I asked if he'd take me for a ride and he did, after my Dad gave him a nod. That. Was. A. Ride. I. Will. NEVER FORGET. He really knew how to throw that car around that winding road along the river. 50 years ago and I'm grinning ear to ear as I type this. How metal machines could give you these memories and emotions is a gift from God. We weren't too late for Sunday night BTU service. Covered alot of ground in a short amount of time.
2:39 mark - Great Video. Since Fords production 427 High Riser (HR) engine was banned after 1964, Ford developed new heads and intake for the 427 called the Medium Riser (MR). They also changed the 427 block to a side-oiler vs the original top oiler
This should be the definitive video on the BOSS 429! Great motor and so glad you told the whole true story on it! John Kasse still makes'em, and makes huge power on pump gas.

Ohio George's twin turbo setup was a true Masterpiece! I have a magazine article from '73 I believe and it said that he was making over 1500hp on gas. Which is unreal because fuel cars of that same time period were in the 1700-1800hp range! Thanks for Watching Andy
FORD's two greatest big block engines are the FE-427 and the 427 SOHC. The 460 was also pretty good, along with the 428 Cobra Jet engine. And the 351 Cleveland is the baddest small block to ever be produced by anyone. In the original movie, "Gone in 60 Seconds, a 1973 351 Boss Ram Air Mustang was the star of this show. That car got put through its paces and then some. Great Chase scenes.
I used to have a 53 ford f-100, short bed, chop top with a 427 sohc and transmission that came out of a 1964 galaxie. I still know exactly where the truck is and also where the engine and transmission both are. The engine and transmission are still bolted together with the factory headers, a radiator, etc. and are still bolted into and engine cradle that I built. I set it up so that I could run the engine periodically in storage while I worked on the truck. Hard times caused a forced sale of them separately. Edit: "R" code not sohc "cammer". I am not sure why my brain went to the sohc. Lol.
Great info. I grew up in Greenwood Indiana and had the opportunity to make the trip to Bob Glidden's shop when I was 16. I have been a gearhead ever since!
The biggest misunderstanding about the Boss 429, is that the street versions were detuned drastically. Mopar did a better street tune to their Hemi than Ford did. The Ford was built to go after the Mopar, and the race version did a lot better. Between those two engines and what they could have done to produce even better versions, was the number one reason NASCAR put the halt to them. They were just getting started good.
You didn't LISTEN to the video. The ports and valves were just to large in diameter for the street. They were designed to run wide open and not for stoplight to stoplight.
The 429 BOSS was only sold to the public to comply with Nascar rules, so it didn't get all dressed up like 302. The 429 was thrown in a car that could fit it and not much else was done. When all it takes is a 302 to beat camaros on the dragstrip, there was no reason to push the 429 on normal buyers. If the 429 got all the attention the BOSS 302 package had, the price would have caused them to sell in the single digits. You could get a Mustang with a 429 BOSS engine, a Mustang with a 302 engine, or a Mustang with the BOSS package and a 302 engine. There never really was a BOSS 429 Mustang, just a regular mustang with a 429 BOSS engine. People who want to see the fully tuned 429 BOSS engine and full BOSS package should look at the 1969 Cyclone Spoiler BOSS
The SOHC would discharge a incredible amount of shrapnel when on Nitro and things went wrong. A few could pull the cams around and do better, but not for long. Short life on everything when on Nitro. It was successful, but very fleeting. One of the reasons for its rareity. They chewed them up quick. Thanks for the vid Unity. I miss Lou'ville. Kentucky is my Heart.
He’s right the Boss 429 was a crazy good looking engine, and the boys in Georgia have learned how to make it crank big HP out of it. The Boss429 Mustang was every muscle car admirers dream

Pretty much was Jon Kaase says about those heads. They need cubic inches or RPM although I wonder just how well some of the Mustangs were tuned. My Dad worked in garage back in the early 70's where the local sheriffs department would bring in their cars for maintenance and tuning. Can't remember the car but the engine was the 440. The sheriffs were complaining about the engine being a dog and so Dad started messing around with it and with the factory specified timing it was doggy but when he increased the timing around 10-12 degrees it turned into a beast. In fact he took one out on a Sunday and got it up to 140mph on the freeway that was near the garage where he worked. The next time he came into work all the sheriffs wanted him to tune there cars though he was told no more road tests.
So wasn't I. But I also desired to know what made the other guys fast and what didn't. There are few ways to get that information. While in Auto Scool, I got to tenure a few weeks at a Chassis Dyno shop that made anything run right and run fast. LOTS of American muscle exotica passed thru there owned by airplane manufacturing execs. "They like to fly on the ground as well". The owner had a Cammer in a 65 Fairlane. Told to stay away from it. After a week of craning my neck while the hood was open, he invited me over and asked if I knew what it was. He was impressed with what I knew about it let alone what it was. I drove a 69 Firebird with a transplanted 327 SBC. No doubt, a small piece of history was there before me. Haven't seen one in the flesh since.
Definitely one of the best looking engines ever built. My 1999 Ford Mustang Cobra's engine 4.6 L Double overhead Cam engine had those really wide valve covers with the spark plugs in the middle of them.
No he didn't. What Bill France saw was a battle of money, not a battle of teams. I'm not suggesting 'spec' cars, that's why I don't watch NASCAR anymore. The teams were going to need sponsors w/ very deep pockets buying very expensive special engines & that was going to push the little guys to the curb. It was going to be a battle between the have's & the have not's. France was between a rock & a hard place. NASCAR should've let the Hemi's run & given the Ford/Mercs a handicap, whatever that might've been. Also to make it easier to give spots to AMC & the GM's. NASCAR needed rivalries.
@@slowpoke7759 Yeah, I was done a while ago & like you said; the 'non-issue that became an issue' justified my contempt. NASCAR can fall off the face of the Earth for all I care now. I hope Tony & Ray get their series going pretty soon. The Daytona 500 is coming up pretty quick. I hope the sponsor's pick up on what you & I & a lot of other fans have realized.
A great engine really. I have owned a bunch of 427's inc a SOHC, A 69 S B9 car that had only 7500 mi on it along with other B9 engines. Currently building a all aluminum 540" boss and adding twin turbos like George did for a daily driver. Using Kaase heads on this one. Have also owned more 428 & 429 CJ/SCJ cars than I can count. Way back in 1979 I bought a new '79 Little red express with the intention of dropping in a 426 Hemi that I had out of a '68 Road Runner I borrowed out the truck and never saw it again. The 426 went to a neighbor that was going to drop it in his '70 Challenger (6-Pak car) Last I heard the challenger and hemi are still sitting in same spot in his dads garage.

I don't think it's been mentioned yet, but this is a very desirable ford motor in the gas 4x4 truck pulling world. They also have 500ci limits and with larger induction, make these motors breath, making big power turning 8000+ rpm when hooked to a sled.
My dad was a hemi guy. He had the 426 in his Plymouth satellite and his opinion of this motor was it was a dog. He said he wasn’t impressed with this motor and being that he kept his car pretty much on the stock side, he said the only car he lost too in the 1/4 mile was a new corvette with a 427 big block. He said the vette was 1000 lbs lighter then his car
You are 100% correct as it wasnt a match for a Hemi on the street.... Thanks for watching and please subscribe as I'm working on a hemi Video as well... Andy
The Boss 429 had a smaller carb than the Boss 302. Big ports hard to get air moving and once it would start the street engine would run out of carb. But they sold enough for the rules.
Ive never understood that... 780 for the Boss 302 and a 735 for the BOSS 429... Thanks for watching and please subscribe and check out my project MIXED UP BOSS. Im putting BOSS 429 style heads on a 429" Windsor stroker.... 750hp or bust NA Andy
@@UnityMotorSportsGarage I heard that Ford engineers thought the smaller carb was the only way to make the cars last long enough to get out of the warranty period.
The valve springs were also a weak point. Changing to the over the counter service part would let them go over 5000 without hitting a "wall". And the carburetor was the next restriction to change. I was told that the small carb made it responsive on the street. Running at a constant higher rpm with the better valve springs and a Dominator carburetor, they were formidable.

It's unfortunate Ford didn't send Fairlane's to Kar Kraft to be modified. The 69 Cobra had 1 engine option. 428scj. It would've been cool if the B0SS 429 was a second option. Wait a tic! I'll save enough $$$$ and build my own BOSS Cobra! Thank you for showing this video. Love the history!

My roommate bought a used Boss Mustang with a 429 and blew the engine while I was riding in it right after he bought it. I glanced at the speedometer and it read 135 MPH right before the engine blew. He ended up installing a rebuilt Cleveland engine in the car which didn’t make sense to me but I suppose the Cleveland was more common and available back then.
I have ridden down the track in all 3 Boss Mustangs, and the Boss 351 was the one that impressed me most. But the Boss 429 was a pretty beast. One man had a 482ci block with a pair of Boss 429 heads. At 11.7:1cr he was ripping up the local drags. Eventually, I remembered seeing him.take the engine down and run it with a Whipple supercharger. Now, it looked far more intimidating and could be a real bear to handle. I'd be willing to bet that he and his son have several builds, if not several sets of heads. This was in Humboldt, iowa in the early 90's .
I am a true Mopar NUT, to the Core! but I can easily say that the Boss429 is one of the most Badass production engines built by Fomoco at the time. One of my neighbors had a grabber yellow 1971 429SCJ Ford Torino, and he Knew how to drive it HARD! I was very sad when he moved last year, he had a REAL DEAL piece of history with him that he took with when he moved out of the area, though Mopar's will always have my heart, but there is reason ford stands for, FIRST ON RACE DAY! Great video!
This is the parallel between the 426 Hemi and the 440. Everybody gets all orgasmic about the Hemi. As a real-world drive, I have seen Hemis whipped by 440s many, many times. So here's the mighty Shotgun motor. If you check the figures in the era, not only was it a lot more money then a Cobra Jet, it wasn't as fast in most cases. Looked great. Wasn't better.
Yup... It took a well tuned Hemi to outrun a 440 on the street.. and you are right the price difference between a CJ and the BOSS was huge... Only to play second fiddle in straight line competition! Thanks for watching! Please Subscribe as I have some cool content coming up! Andy

I was pretty much raised at Gainesville Raceway and had the privilege of seeing Bob Glidden run numerous times. Even have a picture with him holding my freshly autographed Motorcraft Glidden Ford Thunderbird model. Those were the good old days.
That was excellent, really well presented. The history of engines and motorsport can be extremely dry and factual but you have managed to be factual in an interesting way. Growing up in New Zealand, we missed out on most of the great engines, racing and car types from America. So if people like you dont make videos like this, we dont get to re-live it.
Thanks for Watching! Yes Ford went from one extreme to the other on port size... stock 302 heads have ports way to small to the Massive 4V ports big difference! please Subscribe as I have some really good content coming on my MIXED UP BOSS project and other vids on different engine families! Andy
Yeah...all the Chevy, Mopar and AMC SCCA and trans-am racers thought the Boss 302 had "too much cylinder head". After having their asses handed to them.
The Boss 429 had intake ports you could just about roll tennis balls down. We used to fill the floors of the intakes with Devcon and raise the ports into the rocker area resulting in about a golf ball sized intake port giving the enging great low and mid range power for street/strip and truck pull motors. Even bored and stroked them to 618 CI
I bought my first Boss 429 in April 1070, four months after I got home from Vietnam. I had seen a picture of one in one of the magazines and really liked the looks of that car. My first car was a 1964 Plymouth Savoy with a 426 wedge and a four speed. I was a Mopar guy unitl that Boss came out.
I, like several other people, had problems with my engine thanks to a Ford dealer installing the 1970 solid lifter cam. There are four oil control plugs in the block that need to be changed when going from hydraulic to solid lifters and that wasn't done with my engine.
After two years of getting jerked around on getting the engine fixed right, I took it out to Jack Roush in Livonia, Michigan in 1972. That car was no slouch when I first got it but boy did he wake it up. He turned my engine into a 460 using my rods and the pistons from a T series engine plus a 460 crank. I brought a Crane .600 lift 318 degree duration cam and lifters plus an Accel distributor. He supplied a dual quad intake with two 600 Holleys and titanium intake valves. He estimated the horsepower at between 525 and 575 and there was no doubt in my mind when I stuck a leg in both carburetors the first time. It got up to 7500 rpm's in a heartbeat and it had more to go but I didn't. I still have that car.
I bought two others in the meantime which I ended up selling because I couldn't afford to get them restored properly. One of them owns the record for the highest price ever paid for a Boss 429 Mustang when it sold for $605,000 in January 2007 ($550,00 plus 10% to Barrett-Jackson). It was lot #1325 if you want to look it up. It's also listed under the 10 highest prices ever paid for a Mustang at auction. Wish I still had that car. Ed Meyer of Indiana had that car looking like brand new. All three of my Bosses were Candy Apple red and they were all 1969's. That dual quad intake that Jack Roush sold me is reportedly one of only 25 made by Ford. Maybe having the engine built lessened the value of the car but I would never put it back to stock. That car is my pride and joy.
My older brother had to sell his 69 Boss 429 for $5,500 back in the early 80's to help pay for medical school. My father hated that car and couldn't see any value in it. Even then my older brother and I knew it would be worth a fortune in the future. My father was so cheap that pennies would squeal when he spent them. My father drove a 60's something VW bug the first year that had a gas gauge. Never washed or waxed that bug. Had Earl Scheib paint that piece of crap bug and it got stolen a week later.
You only did with it what it was intended to do!

I am a die-hard Mopar guy , and this is an interesting video. I like reading through the comments sections. Best thing to do is not be biased too much. Any intelligent person knows, that a handful of money and knowledge can put most engines at serious competition with each other. Back in the 70s we didn't have a lot of money, so we stuck to the simple go fast changes. Camshaft, lifters, better valve springs and retainers, rear end gears, shift kits in the transmission, stall speed converters, and headers. For us Mopar 6-pack guys, the Performance Kit to change the springs in the vacuum end carburetors was also a must. Other guys might opt for Progressive linkage. Ford guys had plenty of opportunity, and any Mopar guy that had a first look at some of the performance heads that Ford produced got their eyes opened. Ford was no slouch. The street engine Ford Boss 429 had to be mild enough to drive. And that was it's choking point. Make no mistake about it though, this is a great platform that just needed some performance goodies like most any other car manufacturer regular production engines. It's really at all about what you personally like oh, but at the end of the day they are hunks of Steel, Cast iron, and various other metals that make up an engine with a different manufacturers badge on it. hail to all of my Gearhead Brothers out there. I sure miss the 70s, when things were more laid back, cool music, and our world wasn't wound so damn tight
Amen to all of that! I too am a Mopar man at heart.. my first car was a 70 Duster 340... It was fun picking on the 5.0 mustangs back in the day!

@@UnityMotorSportsGarage true statement on the 440 + 6. I have owned those and the small block six pack engines. For their time, pretty impressive. Too many people like to compare half a century ago technology to today's modern fuel-injected engines and suspension on the cars which is completely pointless. Apples to Apples yes but never anything else LOL
@@UnityMotorSportsGarage you gotta be kidding me...had a 89 Notch 5.0, ex patrol car w headers and shifter, I'd smoke that crappy 340 as I did with Corvettes until about C5 came out

@@DennisMerwood-xk8wp remember watching Awesome Bill from Dawsonville with my dad. That old Thunderbird was giving them the blues back in the day. Every time he won they were trying to his dissect car. Also, NASCAR has never been the same since they left the Winston Cup. Wife and I probably watched for another year or so after Earnhardt died. They got to changing the point system so much it just wasn't NASCAR anymore.
@@DvlDawg DviDawg,
I stopped watching it at about the same time you did.
They turned the greatest auto racing show on earth into a farce.
Bill Elliott set the fastest lap in NASCAR history, running 212.809 mph at Talladega Superspeedway on April 30, 1987. At Daytona the following July, all cars were equipped with restrictor plates to limit horsepower.
I watched for about another year and finally gave up in disgust. Have not watched a race since.
Take care my man. Stay safe.
I will rarely watch a race today because the cars are pretty much the same now.
I love every engine, no matter the manufacturer, that started with a 42... but that Boss 429 Mustang, especially the 1969 model with the four headlights, is my absolute favorite

That is so awesome! I just seen your Facebook post.. love that car!
Many years ago I would see a red Boss 429 Mustang with the vanity plate SEMIHEMI just driving around the streets in NY. What a sound that car made :)
Watching the manufacturers chase each other in those days was something we’ll never see again.
yeah....today they have marketologists for this
Right now, If you can afford it, you can buy a 760 HP Shelby Cobra, or a 797 HP Hellcat Charger. Both would stomp those 60's tanks in every way, shape, and form. There has never been faster, or more powerful American muscle. Ever. And this is it. EV is around the corner.
@@deborahchesser7375 No doubt, but EV that is NOT absolutely loaded with tech, that goes 0-60 in less than two seconds, and costs 50-70 thousand dollars is really a better, more practical application. When EV is out of the price range for 3/4 of the population, it only serves the rich.
@@jamesgeorge4874 I had a 69 Mustang with a 427 ( yes it was a orig 428CJ car ) that ran 13:10 with a single traction and motor only, was one of the fastest cars around back then...Now the new Mustangs run High 11's and then you can drive them on a 500 mile road trip.
@@markcatcash4688 I currently have a Fox body Mustang that will run 11.70, is 100% streetable, it scales at 2475 lbs, and has an aluminum 5.3 with a sloppy stage 2 cam, and springs. But you can go buy a Hellcat, bolt on slicks, and beat my mustang, no problem. The point is, America has a horsepower war where you can go to any big 3 dealer, and buy a 600-800 horsepower car, off the showroom floor, NOTHING from the 60's 70's etc. even comes close. You could pit the new Toyota Yaris GR against your big block Mustang, it would beat it, with a 1.5 litre 3 cylinder. Just sayin.

The late great David Pearson won it driving the famous #21 Mercury with the Boss 429, for the legendary Wood brothers team!

Would you believe that the 428 Cobra Jet and Boss 429 are basically the same engine? Also both Hemi, and designed, built and manufactured by Ford before they sold the manufacturing rights to Dodge after they lost a class action lawsuit with the federal government over misleading the public on the true horsepower and torque. The 428 Cobra Jet is what got them in trouble, and after the lawsuit and settlement with all families involved Ford changed the name of the engine because it had been outlawed to ever be a production engine and so was born the Boss 429 and Dodge came with the 426 Hemi and the cops couldn't catch them either and because Ford was the original offending party the Federal government demanded that they gain an edge over both of these engines and so was born the 429 Interceptor. True story.
Thanks for the information about the Boss 429. John Kasse and Jack Roush are also two of the best Boss 429 engine builders.
Kaase is king...
Untold story though. When the Boss 429 came about in 69, there was only one true Ford engine builder. Holman Moody...The same engine builders that made the 427 FE the cornerstone of NASCAR... Either you used their engines or parts or you were just riding around the track... Notice when the Boss 429 came out in NASCAR, there was no 5 year delay on rising to the top... H/M knew their crap...
You are correct! Robert Yates had a huge hand in making it successful he worked at HM for years before going on his own!
Andy
@Steve Gregg true! You have to remember that Jon Kasse got his start by being Dyno Don's crewman then Allen Root did a ton of work on the BOSS head that Glidden ended up running! It was actually offered in the Ford SVO catalog until Glidden had them remove it... Glidden was a very sharp man who knew how to win no matter of the combination! He won championships with Cleveland power, Mopar W2 headed small block, and The BOSS... One fact little known is he built a Chevy Monza to run at Indy in protest of NHRA adding weight to his combo... He didn't do well with it but he did race a Chevy for one race!
Andy
@Steve Gregg Yup.. very smart man
Good job, Andy. The real savior of the Boss 429 in drag racing was Alan Root, who's design update ( given a Ford P/N) addressed some of the original Boss head shortcomings. This basic redesign, tweaked by Kaase, Roush, Glidden, Leonard and others, powered those 1980's IHRA and NHRA Pro Stock cars to such dominance.
Long live the internal combustion engine and the boss 429 what a beast. I had the pleasure of riding in a mustang boss 429 when I was a kid and what a beast it was. 💪🏻💪🏻💪🏻

I had a 1969 Boss 429 in stock form, my 440+6 cuda would blow it off the road easily! then i bought a 1970 Boss 429 that had been worked a little......Holman and Moddy solid lifter cam, dual blueprinted holleys on a medium riser intake, headman 180 degree headers,, scatter shield and McLeod clutch.........OMG that was a tire boiling bad ass! the power from 3000 rpm and up was unreal that car would "relight" the rear tires at 45-50 mph going into 3rd gear!

My brother had a stock SS 396 Chevelle in 1981 that was practically wore out smoked and everything but that dang car would spin the tires going into 3rd with the automatic trans at 70 mph, stock street tires of course but still blow my mind lol!😎👍
When I was a kid and just learning about cars my uncle helped a friend of his swap the intake on his Boss9 he tracked on the weekends. To this day I swear my uncle was able to stick a beer can in the intake ports and not hit the sides, I'm probably mixing up my memories but I remember they were huge. It took a few years to really appreciate that I got to work on such an engine. Great video!
Had Cleveland 4 barrel heads on a Cleveland motor i had in a 79 stepwise. Could almost put my fist in port , they where huge.

Did you know that just about all 427 Cobra roadsters sold to the public weren't even 427s.......they were pumped up 428s. The 427 FE side oilers were put into the 427 Cobra S/C model. Shelby thought the bigger cost of the 427 over the 428 would hurt the car for homologation. However, if a customer found out he had a 428 and bitched about it, Shelby would supply the 427 to him.
Yes indeed. Great little factory street racer.

@@UnityMotorSportsGarage sorry...finished my poop and forgot too....haha.....done
Thanks for the video! Back in the early- mid 70’s I drove a warmed over 1970 Mach 1 with the 351 Windsor. Of course as a young blue oval gear head I lusted after the Boss 9. It was the holy grail car for Ford guys (the SOHC was so rare it wasn’t really thought about). I saw one at the drag strip around 1974 and it actually ran pretty strong. As I recall it ran about a 12.1 with headers, cam, better carb (Holley 3bbl) and slicks. That was actually really impressive back then for a street car. You are totally on point about the engines issues. With the humongous intake ports it was designed to make tons of power way up high in the RPM range when coupled with the right cam and carb. The problem was (per Jon Kaase) that the 429 ci was just too small to create enough pull through those massive ports. As you pointed out a better cam and carb helped up top, but only so much. They still were really sluggish in the low to mid RPM range. Reducing the intake ports via epoxy actually makes the engine run way better all around. The only way to make the as cast heads really work is to add ci. A LOT of ci, like way over 500. Regardless when a blue oval gear head like me sees those Boss 9 valve covers under the hood I hear the angels singing. I guess it’s similar to how MOPAR lovers feel about the Hemi!

Definitely a work of art, a beautiful engine for sure. One wonders if the DOHC Coyote motors may one day be looked back on as fondly.
Too small for & common to be historic
This was the biggest engine I've ever seen in a 2+2. The whole bay of a 69 mustang was this engine. Glorious!!!
Until you had to change the plugs.
Yeah if you notice, they actually had to move the shock towers more toward the wheels to fit those massive cylinder heads
They should have sold it in the Torino instead. Made the a mustang a poor handling turd.
@@DanTheMailman330 they should have put it in the pickup trucks haha
@@machtschnell7452
You're confusing motors, or have no clue regarding the Boss 9 plug location.
Bob Glidden and Jack Roush were my inspirations in the day. The final picture reminded me of my car when it had the tunnel ram sticking through the hood with the holleys topped with velocity stacks. My engine was a 302 tho. The Boss 429 was only a dream.
The Mustang with any of the Boss engines would be tops.

@@UnityMotorSportsGarage Done. Subbed.
Liked the video. I'm mostly a GM guy, but not a "only like this brand and all others stink" guy. Agree with the part at the end that the Boss was one of the best-looking engines. It's bad-ass looking, for sure.
And also agree about its checkered race history. It really just didn't do that well overall, until it was made with big cubes....and even then, it was spotty. Ford fans will point to Glidden....and that's true. But it was Glidden that made the Boss, not the other way around. No other Ford team was really even particularly competitive in the same time frame, that was all Bob Glidden then. He was ahead of the curve for a few years.
With the aftermarket today, you can make anything run however you want it to. But I love hearing about back in the day, when racers had to run the best they could find from factory parts and they couldn't just order up a CNC set of whatever size heads they wanted to along with an unbreakable rotating assy.
Well done!
Thanks for the kind words! I'm not only this brand all other stink! I have Built Fords, Mopars, Chevys and even AMC's.. They all have their strong points and weaknesses..

Nobody was better than Bob and Etta. Bob made magic with his intakes. Remember the guardrail wreck at Atlanta when he took off his firesuit jacket to cover the intake before the camera crew got there?
Dave you are right! Bob and Etta was unstoppable during those years... Thanks for Watching

Back in the 70s, a friend of mine, who was a racer, had a few of these engines in his garage, brand new and still in the factory crates. If only I would have known what they would be worth today. Thanks for the history.
Thanks for watching! I'm glad you enjoyed it

The 351C was called a "Baby Boss" so I understand the 429. They both had canted valves, huge ports and used the same spark plugs. The 351C even had a bigger (780cfm) carb! Great video!
I've owned a few 351 c n none of them had a factory installed 780 cfm.
This is a brute of an engine. Tell you what, Sam is definitely the man to talk to concerning anything 429. Very interesting video, thanks

So true! Thanks for Watching!
Andy
I live 5 minutes from his shop. It’s an amazing place to see inside.
I have a friend who is building a 67' Fairlane with a Boss 520 in it. Chuck Lawrence, who was an engine builder for Kasse, built the engine with parts he got from John. On the dyno, the engine had an 1100 Dominator on it, and it was starving for fuel. It turned 820 hp and I think it was 785 torque. When it goes in the car, they will put a double Sniper system on it which should get it to 900 hp.
If the Kasse engine is so good why is it not in Nhra prp stock going up against the GM cars???
@raginroadrunner read the NHRA rules! The Ford big block isn't legal in ProStock. The rules are completely based off of the GM Big Block bore spacing

When I was a teen I had a Ford Motorsport catalogue from the 80s (I was fixing up a Mustang at the time, and was working on the engine). And all the motors and parts were Boss 429. There was a large selection of heads. I was just building a daily driver small block. But it was interesting what you could order straight from Ford, in an era when factor V8s didn't even have 200 hp.
You people that seem to be unaware that the METHOD of rating of max horsepower of an engine Changed Radically after 1970/1971, are not very smart. The industry just made up false ratings to fool the buying public.Plain and simple, just Lie about it, and foolish people will believe the lies.
Kinda like Mopar's Direct-Connection. They had a book on how to 'build' the engine with the over the counterparts. ie. W2 heads, I put a 360 in a 79 D50, that's weight was 3029 lbs with the small block. 10.09 in 1985.
6:00 mark - The factory ram air was very restrictive, but was required in certain classes. It was competing in a class of Hemi's that came factory equipped with dual quads. In Stock type racing it was a 11- second car. I recently posted a story on this. In 1970 Kar Kraft offered a kit that included jets and other stuff to make it 0.20 faster then a 1970 SCJ. Great Video!
We built those engines at the Lima Engine Plant. I drove many pistons in the Blue Crescent engine (our code name) for the 429 boss. We were also making the 429/460 regular engines with wedge heads. Some of those went into the Super Cobras. We made some 460's for the presidential
motorcade. The 429 boss didn't have a head gasket, O rings around the cylinders and neoprene rings around water ports, etc. Valves were ,010 bigger that the Chrysler Hemi and the intake/exhaust ports were huge, heads were aluminum. Each rocker arm had it's own pedestal and run on needle bearings. I saw several running on the dynos at the plant......one at 5000 rpm for many ? hours just to see what would give up. I believe some went almost 24 hours. Exhausts would be glowing............!

Back in 1969 of all magazines that actually tested bone stock cars the 1969 Boss 429 T was number 2 of fastest cars. Getting beat by only the ‘69 GTX 426 Hemi Auto with a 4.10 gear. Very close the 426 went 13.32 @ 107 vs Boss 9 at 13.34 @ 107. Bigger carb on boss with better exhaust and they ran very well. I owned a 1 of 6 1967 Mercury Capri R code (427 8v) 4 spd and it was no doubt quicker than my friends 1967 Hemi GTX. I did add a limited slip diff to the 3.89 gear. Ford refused to put locking or limited slip rears in the 427 comets or Fairlane’s for “safety” so any magazine article from back then was with a open diff. Crazy really but one still ran a 13.51 @ 108 with open diff.
My Uncle had a boss 429 he ran at Atlanta motor speedway in the road racing track. He dominated with it. It might not have been a good drag racer but it was a great engine for the nasser and road racing tracks.
That is where that engine shined! Thanks for watching and sharing! Please subscribe as I have some really good content coming up!

Thank You for your service and the great fast fords story..
In the Mustang, the Boss 429 was choked by restrictive intake & massively choked exhaust.I do love you mentioned the 427 sohc(cammer) The cammer was never approved because Chevy found out about it & fought it's approval with all sanctioning bodies...this also is what got The Hemi banned.
Helped a buddy put headers on his 70 Boss 429, we had to go up 6 jet sizes to get it to run right again. The speed shop was amazed that it took that much.
I was a weekender at Sunshine drag strip in Florida. I had my S code prepared by Speed Specialties of St. Petersberg. With cutouts under the doors, I ran "A" stock and did very well with the Bow Tie guys. It ran quicker than the stock SS 396's at that time in 1970.
In my Car Show years.. production assistant.. I went to many a Show.. Only Once Good Guys Show in the San Francisco area.. Seen Boss Stang on the road to the show Highway driving.. then found him.. Man oh Man.. up close it's Crazy looking.. this was about 12 years ago now.. hope he's still driving it.. but you know the price on these has Gone up.. to say the least.. Great Post UNITY..

You should see what cars show up at Ford Carlisle in PA once.......
Seen many a rare Ford/Merc/Lincolns there over the years.A few I remember seeing in 2012 was Fast Eddie Schartman's Pro Stock '70 Boss 9 Cougar (1 of 2), Dyno Don's Pinto,Hayden Profitt's AFX Comet, 1 of 1 '67 Shelby GT500 428 convert.Back in the early 90's ('91? '92?) I was able to park my '64 Fairlane 500 sedan beside a couple orig. Tbolts,and chat with a old man for a few hours that had his '63 K code since new,the Fairlane was the theme that year.
There's a 427 SOHC Tbucket and a Boss 9 Mustang or two that come to the local shows now and again that we enter.

growing up I knew the greatest car geek ever, he was a school teacher in metal trades, and always at auto shop across hall, he helped kids stay out of trouble & helped them focus toward cars, trucks, metal work, yes helped me from being a dropout & who knows what. he gave his life toward helping kids, and never had wife or family, died alone in nursing home a few years ago. no idea what happened to his cars. he lived in rural VA.
anyway he owned a 1969 & 1970 Boss 429 Mustangs, I know he had a few 427 SOHC powered vehicles, 1 was a drag race only mustang, and a few spare engines, a couple Torino super cobrajet drag packs, 69& 70? or 68 & 69? 1 was automatic, which I helped build in classes, 1 was 4 speed. a radical 78 king cobra Mustang II, yeah I know, but for a daily driver with .700 lift cam in a small block, it was radical, he had a totally bad ass pickup for a more fun daily driver with a tunnel rammed dual carb 429, all those in the mid to late 1980's

I do remember watching him race in them! Great memories I'll remember for the rest of my life!
Yeah Ohio George with that combo pretty much killed the class he was running and NHRA banned the Turbo combo... Which is sad considering how far ahead of his time he was...

I in January of 69 ,. I was at North Western Ford, Milwaukee WI.
I saw a 69 plan Jane while Sport Roof Mustang,
It had the Boss 429 stuffed into it!!! WOW
I was so impressed,
I was home from Nam less than a month
Way back as a teen I was a passenger in a boss 429 a church member and a 69 hemi road runner, my chevron boss son. I love Ford but was brutal in 4 shift, banging & lifting the stang. But didn't feel the speed. But the hemi. It's was a special edition was just one one long lift and we were 60-70'area. The close I felt that again was in a Yamaha GS 1,000 the first model 11 s bike. The second gear pull 20-70 was like 2-3 second. There is a difference from brute torque power. Than on the cam or live nitro power that can't be beat. Torque is fun & show & noise. LOL. His hemi was all black with back 50s on center lines beautiful car.
It's has to be around. And the cam hooker sound was perfect.
Great video, thanks! I'm a Mopar guy and I know the 426 Hemi is a legend but it has a lot of shortcomings as well. But it worked great back in the day. The Boss 429 seems similar to the Ram Air V Pontiac engine. It had the same problems and was treated the same by racers during that era. I mean everything from ports that were too big to flow well at low lifts/rpms to rotating assemblies that were so heavy they became their own worst enemies.

@@UnityMotorSportsGarage You're welcome! I've seen those stroker kits for the 351W but the rod angle ratio at 428-429ci seemed a little too severe for me. Sidewall loading would be pretty high.
I'm not a fan of Ford's "mod" engines either. Don't like their small 3.93 inch bore spacing. I think 3.7 inches is the maximum diameter bore that's possible.

My father worked for Ford in the 50's and 60's as VP of the Truck Div., then left and bought up several Ford, Mercury, Lincoln dealerships throughout the mid-west to revive, we also got the exclusive Shelby Cobra and de Tomasso Pantera franchises for all of the midwest (his factory connections paid off) because he sponsored Cobra Racing. He ordered me a custom 1970 Mustang "Boss", but instead of a 302 ci V8, mine came with a 351ci "Cleveland" "Semi-Hemi Head" V8 and dual Quads, and factory pipe headers. Because it (with the 351 Cleveland, built on the Ford Small Block) was so light, it was FASTER than the 428 Boss, and I clobbered every Hemo Dodge and Chevy 427 a the drag strip. The 351ci Cleveland Semi-Hemi was a far better engine than the 429 Boss or the 427 "Cammer".
The Cleveland is going to be an upcoming video for me down the road! Thanks for Watching

When I was an 11 year old kid, a used car dealer that was a member of our church, pulled into the parking lot right before Sunday evening services. I ran over to his Mustang and asked "Wow Ed is this a Boss 302"? He says- "Nah, those are fer girls. This thang's a Boss 429". I asked if he'd take me for a ride and he did, after my Dad gave him a nod. That. Was. A. Ride. I. Will. NEVER FORGET. He really knew how to throw that car around that winding road along the river. 50 years ago and I'm grinning ear to ear as I type this. How metal machines could give you these memories and emotions is a gift from God. We weren't too late for Sunday night BTU service. Covered alot of ground in a short amount of time.
2:39 mark - Great Video. Since Fords production 427 High Riser (HR) engine was banned after 1964, Ford developed new heads and intake for the 427 called the Medium Riser (MR). They also changed the 427 block to a side-oiler vs the original top oiler

Ohio George's twin turbo setup was a true Masterpiece! I have a magazine article from '73 I believe and it said that he was making over 1500hp on gas. Which is unreal because fuel cars of that same time period were in the 1700-1800hp range! Thanks for Watching
Andy
@@UnityMotorSportsGarage I read that article too. He said he de-tuned in order to get traction if I remember correctly.
FORD's two greatest big block engines are the FE-427 and the 427 SOHC. The 460 was also pretty good, along with the 428 Cobra Jet engine. And the 351 Cleveland is the baddest small block to ever be produced by anyone. In the original movie, "Gone in 60 Seconds, a 1973 351 Boss Ram Air Mustang was the star of this show. That car got put through its paces and then some. Great Chase scenes.
I used to have a 53 ford f-100, short bed, chop top with a 427 sohc and transmission that came out of a 1964 galaxie.
I still know exactly where the truck is and also where the engine and transmission both are. The engine and transmission are still bolted together with the factory headers, a radiator, etc. and are still bolted into and engine cradle that I built.
I set it up so that I could run the engine periodically in storage while I worked on the truck. Hard times caused a forced sale of them separately.
Edit: "R" code not sohc "cammer". I am not sure why my brain went to the sohc. Lol.
'73 anything was low compression smog pump choked......don't believe everything you see at the movies
Great info.
I grew up in Greenwood Indiana and had the opportunity to make the trip to Bob Glidden's shop when I was 16.
I have been a gearhead ever since!
The biggest misunderstanding about the Boss 429, is that the street versions were detuned drastically. Mopar did a better street tune to their Hemi than Ford did. The Ford was built to go after the Mopar, and the race version did a lot better. Between those two engines and what they could have done to produce even better versions, was the number one reason NASCAR put the halt to them. They were just getting started good.
It could have been packaged better for the street that is forsure! Thanks for watching
Andy
The race version did more than better beat the 426 hemi at Nascar. The Boss lived up to its name.
They had valve springs that limited rpm to 5000 in the Mustangs. The 2 King Cobra Torinos had the Boss 9.
You didn't LISTEN to the video. The ports and valves were just to large in diameter for the street. They were designed to run wide open and not for stoplight to stoplight.
The 429 BOSS was only sold to the public to comply with Nascar rules, so it didn't get all dressed up like 302. The 429 was thrown in a car that could fit it and not much else was done. When all it takes is a 302 to beat camaros on the dragstrip, there was no reason to push the 429 on normal buyers. If the 429 got all the attention the BOSS 302 package had, the price would have caused them to sell in the single digits. You could get a Mustang with a 429 BOSS engine, a Mustang with a 302 engine, or a Mustang with the BOSS package and a 302 engine. There never really was a BOSS 429 Mustang, just a regular mustang with a 429 BOSS engine. People who want to see the fully tuned 429 BOSS engine and full BOSS package should look at the 1969 Cyclone Spoiler BOSS
I am a Mopar guy and I spent years racing the Hemi in NHRA. Thank you for the interesting Ford video.
Stay tuned Hemi video on the way!
Magic Andy. Sharing is Caring. Thanks for networking and talking with the Guru's.
Thanks Dean, it is such a honor getting to talk to the folks who actually raced these legendary engines back in the day!
Fantastic video I have a Old Boss 429 but I’m a road racing Le Mans guy
Thank you for watching! That is pretty awesome...
Andy
I loved this video!! Anything that mentions Bob Glidden is tops in my opinion! 🇺🇸😎
The SOHC would discharge a incredible amount of shrapnel when on Nitro and things went wrong. A few could pull the cams around and do better, but not for long. Short life on everything when on Nitro. It was successful, but very fleeting. One of the reasons for its rareity. They chewed them up quick. Thanks for the vid Unity. I miss Lou'ville. Kentucky is my Heart.
Thanks for watching!
You are right.. about the SOHC on nitro. When things were good.. it was good but when it went bad.. watch out!
Andy
He’s right the Boss 429 was a crazy good looking engine, and the boys in Georgia have learned how to make it crank big HP out of it. The Boss429 Mustang was every muscle car admirers dream
Kasse is the King of the BOSS 9! Thanks for Watching and please subscribe! Im putting BOSS 429 style heads on a 429" Stroker Windsor called MIXED UP BOSS
Pretty much was Jon Kaase says about those heads. They need cubic inches or RPM although I wonder just how well some of the Mustangs were tuned. My Dad worked in garage back in the early 70's where the local sheriffs department would bring in their cars for maintenance and tuning. Can't remember the car but the engine was the 440. The sheriffs were complaining about the engine being a dog and so Dad started messing around with it and with the factory specified timing it was doggy but when he increased the timing around 10-12 degrees it turned into a beast. In fact he took one out on a Sunday and got it up to 140mph on the freeway that was near the garage where he worked. The next time he came into work all the sheriffs wanted him to tune there cars though he was told no more road tests.
I'm a Chevy guy but always thought that the SOHC and Boss 429 were the baddest of the bad.
@Amplass 333 Nah, I love them all. So happens I grew up with SBC's.
So wasn't I. But I also desired to know what made the other guys fast and what didn't. There are few ways to get that information. While in Auto Scool, I got to tenure a few weeks at a Chassis Dyno shop that made anything run right and run fast. LOTS of American muscle exotica passed thru there owned by airplane manufacturing execs. "They like to fly on the ground as well". The owner had a Cammer in a 65 Fairlane. Told to stay away from it. After a week of craning my neck while the hood was open, he invited me over and asked if I knew what it was. He was impressed with what I knew about it let alone what it was. I drove a 69 Firebird with a transplanted 327 SBC. No doubt, a small piece of history was there before me. Haven't seen one in the flesh since.
Definitely one of the best looking engines ever built. My 1999 Ford Mustang Cobra's engine 4.6 L Double overhead Cam engine had those really wide valve covers with the spark plugs in the middle of them.
The France Family, ruining innovation since they created NASCAR
No he didn't. What Bill France saw was a battle of money, not a battle of teams. I'm not suggesting 'spec' cars, that's why I don't watch NASCAR anymore. The teams were going to need sponsors w/ very deep pockets buying very expensive special engines & that was going to push the little guys to the curb. It was going to be a battle between the have's & the have not's. France was between a rock & a hard place. NASCAR should've let the Hemi's run & given the Ford/Mercs a handicap, whatever that might've been. Also to make it easier to give spots to AMC & the GM's. NASCAR needed rivalries.
yep, he ran Smokey Yunick away from NASCAR ....
@@carmiethompson2676 NASCAR’s Jessie Smollet moments at Talladega last year done it for me.
@@slowpoke7759 Yeah, I was done a while ago & like you said; the 'non-issue that became an issue' justified my contempt. NASCAR can fall off the face of the Earth for all I care now. I hope Tony & Ray get their series going pretty soon. The Daytona 500 is coming up pretty quick. I hope the sponsor's pick up on what you & I & a lot of other fans have realized.
@@carmiethompson2676 LOL. So what we have today is economy racing. Bull Fucking Shit.
In 1975 I saw a 1970 Boss 429 in London England. It was Ford Blue, an awesome.
A great engine really. I have owned a bunch of 427's inc a SOHC, A 69 S B9 car that had only 7500 mi on it along with other B9 engines. Currently building a all aluminum 540" boss and adding twin turbos like George did for a daily driver. Using Kaase heads on this one. Have also owned more 428 & 429 CJ/SCJ cars than I can count. Way back in 1979 I bought a new '79 Little red express with the intention of dropping in a 426 Hemi that I had out of a '68 Road Runner I borrowed out the truck and never saw it again. The 426 went to a neighbor that was going to drop it in his '70 Challenger (6-Pak car) Last I heard the challenger and hemi are still sitting in same spot in his dads garage.

I've heard with those ports and heavy internals running 9500rpm for hours was cake and what that motor loved most.
A friend had a Boss 429 Mustang. Those motors had 'O' rings for head gaskets, always leaking!
True, the service procedure for head "O" rings was crazy.. You have to use feeler guages between the deck surfaces when you are torqueing the heads down! Many horror stories...

I don't think it's been mentioned yet, but this is a very desirable ford motor in the gas 4x4 truck pulling world. They also have 500ci limits and with larger induction, make these motors breath, making big power turning 8000+ rpm when hooked to a sled.
My dad was a hemi guy. He had the 426 in his Plymouth satellite and his opinion of this motor was it was a dog. He said he wasn’t impressed with this motor and being that he kept his car pretty much on the stock side, he said the only car he lost too in the 1/4 mile was a new corvette with a 427 big block. He said the vette was 1000 lbs lighter then his car
You are 100% correct as it wasnt a match for a Hemi on the street.... Thanks for watching and please subscribe as I'm working on a hemi Video as well...

The Boss 429 had a smaller carb than the Boss 302. Big ports hard to get air moving and once it would start the street engine would run out of carb. But they sold enough for the rules.

Andy
@@UnityMotorSportsGarage I heard that Ford engineers thought the smaller carb was the only way to make the cars last long enough to get out of the warranty period.
@@UnityMotorSportsGarage Great job on this video!!
The valve springs were also a weak point. Changing to the over the counter service part would let them go over 5000 without hitting a "wall". And the carburetor was the next restriction to change. I was told that the small carb made it responsive on the street. Running at a constant higher rpm with the better valve springs and a Dominator carburetor, they were formidable.
Great video! I have a Boss 429. It's in a '56 F-100 but the truck isn't going to be finished anytime soon. Ran out of money.
That is awesome! I too fully understand the money... I've been working on project MIXED UP BOSS for a year and it is going in my '71 F100 Casper... Thanks for Watching!

Excellent video. May explain why a certain 429 racer at Brainerd back in the day told me not to take picks of his spare motor in the trailer.
Emission laws were the Achilles Heel of the Boss 429. A 735cfm Holley? See the smog pump? Just go to Muscle Car of the Week, Top 10 quickest Muscle Cars of 1969. Hosted by Kevin Oeste. Posted a couple of days ago. #1quickest? drum roll.. 1969 Roadrunner HEMI auto. 13.32 @ 107.65mph. #2 quickest? gazoo.. 1969 BOSS 429. 13.34 @ 107mph.
My dad has a 1971 mach 1 429 scj with drag pack drove it twice when I was a teenager learning how to drive.Was a fast car
I think it had 60 pound clutch I believe had been in his garage about 35 or so years. Nice to learn the history 🖒
It's unfortunate Ford didn't send Fairlane's to Kar Kraft to be modified. The 69 Cobra had 1 engine option. 428scj. It would've been cool if the B0SS 429 was a second option. Wait a tic! I'll save enough $$$$ and build my own BOSS Cobra! Thank you for showing this video. Love the history!

Great video! That is how I understood it. More oval track than dragstrip at first. Eventually brought into its own.
My roommate bought a used Boss Mustang with a 429 and blew the engine while I was riding in it right after he bought it. I glanced at the speedometer and it read 135 MPH right before the engine blew. He ended up installing a rebuilt Cleveland engine in the car which didn’t make sense to me but I suppose the Cleveland was more common and available back then.
I have ridden down the track in all 3 Boss Mustangs, and the Boss 351 was the one that impressed me most. But the Boss 429 was a pretty beast. One man had a 482ci block with a pair of Boss 429 heads. At 11.7:1cr he was ripping up the local drags. Eventually, I remembered seeing him.take the engine down and run it with a Whipple supercharger. Now, it looked far more intimidating and could be a real bear to handle. I'd be willing to bet that he and his son have several builds, if not several sets of heads. This was in Humboldt, iowa in the early 90's .
I agree the BOSS 351 is the most overshadowed.. but will run hard! I'm actually working on a 351 Cleveland video

I am a true Mopar NUT, to the Core! but I can easily say that the Boss429 is one of the most Badass production engines built by Fomoco at the time. One of my neighbors had a grabber yellow 1971 429SCJ Ford Torino, and he Knew how to drive it HARD! I was very sad when he moved last year, he had a REAL DEAL piece of history with him that he took with when he moved out of the area, though Mopar's will always have my heart, but there is reason ford stands for, FIRST ON RACE DAY! Great video!
Thanks for the kind words and for Watching! You might want to check out my Hemi video...
Andy
@@UnityMotorSportsGarage Thanks for outstanding content guys, Hemi's are definitely my thing, so I will be sure to check it out.
This is the parallel between the 426 Hemi and the 440. Everybody gets all orgasmic about the Hemi. As a real-world drive, I have seen Hemis whipped by 440s many, many times. So here's the mighty Shotgun motor. If you check the figures in the era, not only was it a lot more money then a Cobra Jet, it wasn't as fast in most cases. Looked great. Wasn't better.
Yup... It took a well tuned Hemi to outrun a 440 on the street.. and you are right the price difference between a CJ and the BOSS was huge... Only to play second fiddle in straight line competition!

a 383 B Block is even faster sometimes than a 426 Hemi in the 1/8th mile. I suppose a lot of it is jetting, timing, traction, and reaction time.
Great video sir. Love your delivery and the great period footage. Really different from other presenters who seem to think they are part of (if not most of) the story. The "down home, southern (Nascar country) accent" doesn't hurt either.

That was excellent, really well presented. The history of engines and motorsport can be extremely dry and factual but you have managed to be factual in an interesting way.

Yeah...all the Chevy, Mopar and AMC SCCA and trans-am racers thought the Boss 302 had "too much cylinder head". After having their asses handed to them.
Ford's answer after the tunnel port 302 disaster was the BOSS 302 and turn it 8000 rpm!! Problem solved!
Andy
@@oldmusher it made for a horrible street engine is what I tried to infer. Not the End of the World.
A good race engine it was. 👌
The Boss 429 had intake ports you could just about roll tennis balls down. We used to fill the floors of the intakes with Devcon and raise the ports into the rocker area resulting in about a golf ball sized intake port giving the enging great low and mid range power for street/strip and truck pull motors. Even bored and stroked them to 618 CI
Great vid mate from down under 🇦🇺
