Whenever Automotive Specialists ( / automotive-specialists... ) and Johnson's Hot Rod Shop (johnsonshotrodshop.com/) team up for a build, you can bet the result will be groundbreaking. This time they wanted to come up with a truly unique engine for a '50s-era Chevy Suburban build, and the result is a classic Chevy Straight Six with twin turbos, six throttle bodies, two intercoolers, fuel injection and more cool tricks than a three-ring circus.

Gentlemen...I am a retired Service Director from Cadillac.....I did extensive armature drag racing Mopar Hemi engines in B/ MP in the 70's....Enough about me............I "bumped" into this six cylinder build and I am ASTOUNDED at what you can get out of a small cubic inch motor like this. Any enthusiast can see this was a "no holds barred money motor.".............. I LOVED the cam sensor idea. Thank you !! You have a new fan here in New Jersey ! God bless !
It is impressive that this engine is putting out 588 ft pounds tq at 3700 rpm.
What kinda times did u turn in that Hemi in your B/MP class?
Powernation made a Ford 300 six and put a turbo on it and it made over 500 horsepower with just one turbo. Go check it out on there channel it's a white painted motor with turbo
How fun would that be, to have the money, resources and time to be able to fabricate and design one of a kind parts to modernize a classic engine, with new technology. I can see why the guy still wants to come to work everyday!
How tragically ironic that with age , it is time that becomes the more precious resource.
What a great opportunity to get the knowledge made available 🙏🏼
No doubt
@@jamessharp9790 So true !
These inlines are so awesome. It's a shame that so many one offs have to be made.
Keith is a true engine builder. Anyone can slap together parts and make them work. What he made is art.
Man you are absolutely right the man is a mastrr at what he does best and thats to create ,,my hat is off to him
I am amazed at his engine building skills and insight that he has.
Holy Crap !
This guy is half Artist & Half Engineer.
I raced Superbikes for a couple decades and know the difference between parts changers & True engine builders.
This guy is engine builders engine builder.
That torque "curve" is unbelievably straight. Such fine workmanship by a master builder!
Even in the old days the right work made those six's evil. Heard a story once a guy showed up with one to a circle track full of V8's. They ended up wrecking the guy out cause he was fucking charging up to the front like a bat out of hell.
@@jr540123
The GMC 302" ruled back in the day; add a Wayne head and you were good to go....
I was thinking the exact same thing
That's a I-6 for ya'. Smooth as silk FAT torque, brought to you by Chevrolet.
@@rgroove1970 That thing is wild. I've never seen a car bounce the front tires down the whole stretch and not look scary as shit the whole way.
I'm telling you man, stories about builds like these are why I LOVE this channel. You cover some seriously outrageous builds. I'd REALLY love to see a high horsepower Y-block build.
Thanks a lot!
fun? yes. reliable? 🤷
@@user-wu4fg7tc9y Why not? Have you seen the kind of horsepower these boys are building today? If the builder is worth his salt, reliability will be there ...how long? PM and you can have a lot of fun.
@@charlesangell_bulmtl well fair enough, but the more you fuck with an engine the less reliable overall right? talking every day drivers tho
@@TheHorsepowerMonster If the ENGINE OIL PUMP belt breaks how fast do you need to shut off the engine to avoid locking it up due to oil starvation ? I would also like to know if you have done any engine rebuilds on the old INTERNATIONAL HARVESTER 304 & 345 or 392 engines in the IH Scouts ?
Keith is like the "Uncle" that everyone wants and needs! What a Gentleman and a Scholar! The man knows what he is doing and one can tell, he definitely has the talent and passion for it! It shows, in his works of art! Keep 'em comin' "Uncle Keith!" :)
That truck will pull the same with or without a trailer. Masterpiece.
I just love straight 6 engines build ups. And this one is definitely my favorite. What an absolutely gem.
sorry but that sounds like Arse sure awesome expensive setup but my old junkyard pick a part $50 crossflow ford 4.2 made 600hp ate 8 year ago.
@@altruismfirst6489 You are full of shit are your eyes brown?
Power nation did a similar build on an old ford six that was used as a power plant for a city weed abatement sprayer or some such.
It came to them outputting like 80 HP. Left them putting out north of 500 HP.
Man! You guys ARE engine builders. You've practically redesigned and fabricated 90% of the old straight 6. Awesome job.
An engine builder who does any amount of fabricating is a true artist and has my utmost respect👌🏻.
This is hands down one of the coolest engine builds ever. Probably the most unique straight 6 I've ever seen. And I've seen a ton of BMW and Toyota builds haha
Now this is an amazing build. A lot of ground breaking tech compared to back then, and on a motor that parts aren't ever so readily available or existent, this really stands out to me.
You can get these at any junkyard for pennies. Now doing what they did to it did not cost pennies. I have seen cheap builds getting a reliable 350-400hp with cheap piston, and internal upgrades, and a large diesel turbo. I think most of the builds were about 2200 dollars. I would like to do an inline 6 build for industrial machines I have, but I live somewhere the roads are a sheet of ice half the year so we don't really do hotrods. I am more into 2 cycle stuff where we are just making toys, and we all drive electric cars. Small engines are easy to tinker with, cheap, and just as fun. This was an incredible build with tight tolerances. My first inline 6 I got for 150 bucks. I changed the Head gasket at 15yo, and did upgrades, and it fired up the first crank. The build they did could easily do 700hp if you push it. I like their build philosophy at keeping it at 4600RPM- makes that build bulletproof. That thing will make reliable HP for as long as you can still get fuel for it.
Keith has probably forgotten more than most know!! The "this is what separates a true builder from an assembler" reference is right on point!! Awesome video thanks bud 🤙🤘🔥
Any time you get Holley to pay you to design a sbc intake, and the. Pay you a licensing fee for each unit sold.. you know a lil something about something! 😉
Most of technology he used didn’t exist when he started building engines. I see a man who has learned continuously throughout his career. I like it when guys don’t get set in their ways to the point of getting passed over by the times we live in.
The best part of watching this is that Keith is so freaking HUMBLE. He's obviously not difficult to work with and eager to keep challenging himself as well.
Would hire him in a nanosecond.
You couldn't be more right on your comment. I've assembled some engines in my lifetime, but I am absolutely no engine builder. When I had my 709 wheel horsepower 1.8L B18C5 engine built for my Civic, I had it assembled by a well-known machine shop and engine builder. I paid them to balance, machine, and assemble the long block, and I assembled the head, turbo, and all of the other components so that I knew the hard part was done properly.
This isn't just an engine build.. this is an engineering master piece!
OMG. Not really enough words to describe the uniqueness of this build, and of course the talent of the men at the shop !
Wow
I had a 76 elco with the 250 cube straight 6
We ditched the carter for a high flow twin Weber, cut and welded and made a dually with 2x twin Webers (down drafts) and changed out stock cam for a “town and country” grind with solid instead of hydraulic lifters. We then fitted a custom made tube extractor manifolds and that few mods changed that Elco into a reasonable sleeper in 78.
As students at the time it was a labour of love by my father and friends that we made a plan because there was no issue with money. Theres only an issue with money if you got some.
We didnt have any. I was working 4 jobs to pay my tuition.
So the Elco was an old sleeper in the true sense of the word. Scratch mods sounds about right cause we scratched around to do anything.
And while the Elco was being worked on everytime, we resorted to mans ancient transport- boot 🥾 power...
But it was a hoot
Loved that car. Sold it with 325,000 miles on it and the motor had never been opened for repair work.
Enjoyed this, wish i had 525 hp back then, not sure if there was anything that would have caught me(with the 3 speed stick shift)
Keep on keeping on
10psi and 600lb/ft of torque?! Can we just take a moment to appreciate that a 1950s block and crank with a performance head designed in the same era is making what even LS guys dream about nowadays? The amount of little details to squeeze all that thump out of this lump is truly mind boggling.
this is by far 1 of the coolest and most beautiful engines builds I have seen in a long time. All of us engine builders and or engine enthusiasts have soo much to learn from these artist and if we don't get with builders and learn this lost art of designing, fabricating, and building engines like these artists engine builders will be gone and these techniques will be lost forever. us younger builders tend to only look at the future and the next fad coming, which I am guilty of as well but we forget where hot rodding came from and what it takes to truly call yourself an engine builder and not just another parts installer. Thank you very much for the video and please keep em coming.
That man is a certified genius! I cannot believe his abilities!
Amazing work!
I could only daydream about how cool it would be to learn from someone like that. Awesome.
Man love that flat as a table torque curve, it’ll be interesting to see the finished rig once it’s completed. Super nice build guys.
@R K its not a v8 that are known to low end torque its a straight 6.
Straight sixes have always been known for having torque, that's why they worked good in work trucks.
@@bigredc222 Precisely!!! They were designed to get things moving and not intended for rpm. The rotating mass of the the crankshaft and it's length are a testament to that! Beautiful build and master craftsman.
@@bigredc222 ,
We built a Chevy 292 inline 6 a bunch of years back, we used 302 chevy pistons in it, once we got it warmed up when it idled it sounded like a two stroke engine, lol, we had a lot of fun in our free time at the machine shop.
Man the sound of turbos never gets old! What an amazing accomplishment they've pulled off, such an amazing build!
Unbelievable! That torque coming on right off the get go and not really having to spin it up much would be a lot of fun on the street. I built a 4.0 liter for a 66 rambler that was nothing close but made good power considering it was never meant to make much power. Nice work and I would love to just be in the shop with this guy to learn from the greats. Not many left and getting fewer every year.
There's no torque "Curve", that's a torque plateau. A Torque Hoodoo. Someone will ask you about the power band and the owner will just say YES. I wonder how good it'll be for towing, or even what mileage it'll get- that engine's gotta be super efficient now.
Totally agree with Kieth about making odd one-off and custom stuff. Before electrics take over, we are giving gas the greatest send-off possible- The LS has made huge power a breeze, cheap machining tools are everywhere (both from classic American cast iron to slave-built Chinese stuff) and information and help is literally a forum away. Thanks so much for showing us all this cool stuff HM!
Bite your tongue...electric cars suck unless it's a hybrid. Two stroke supercharged diesels ARE STILL the most efficient power plants. Been working for the Electromotive since the 50s and they only carry a bare minimum of battery.👍 The EPA is in the back pocket of industry, we should be getting a minimum of 100mpg if the EPA were really doing it's job...Old tech and the new 👍
@@charlesangell_bulmtl okay boomer
But if they're so efficient, why are rx8s such gas hogs? Could ot have something to do with low torque?
@@MrPaige222 I'm not a rotary guy so grain of salt, but rotaries have terrible problems making NOx and other oxides because they burn so hot- and oxides are what you get with a hot burn. The renesis had to avoid that with a unique air intake design that partially strangled them.
@@girthquake1413
I'm right there with you. I have little to no respect for that particular engine. I understand the tiny displacement in regards to the horsepower output, but it comes at such a huge cost in reliability and fuel economy. No thanks. It's no wonder an RX8 is practically worthless
This is by far the most incredible engine build I have seen. You always seem to get all the fine details in there, which makes the videos shine in my opinion.
Hey, thanks a lot!
Very well said and well deserved comment. You did a fantastic job not only showcasing the engine, but Keith himself.
@@TheHorsepowerMonster i have a wonderful for Keith Dorton could a carbonated engine be turned into a Fuel injection 💉 system with out the distributor hi 👋 from 🇨🇦 #YSW
That's some incredible power for such humble beginnings from nearly 100 years ago.
The torque from that beast is just awesome. Talk about a tire shredder. You are absolutely right in that this dude is an engine builder. Seeing a problem and solving it is what separates the true mechanics and engine builders from the parts changers.
This is hands down the best engine channel on UA-cam.
That's a big compliment. Thanks a lot!
That aluminum Wayne head, is a game changer for the straight 6...very nice set-up.
Finally!!! Finally someone does a beautiful restoration on that old Suburban, and they get the wheels/tires right, instead of jacking the truck up even higher and putting on ridiculously big in diameter and ridiculously wide off-road tires with white lettering, like so many people can't resist. Nice job!!! :)
It's wonderful to see engine masters work on 'one-off' designs. It demonstrates a level of skill and ingenuity that you just don't see with current engines and hoards of available, aftermarket parts.
I could listen to Keith talk about engine building all day. What an absolute legend! I'll die a happy man if I even get close to the skill that man has in his little finger.
This man has likely forgotten more then we are ever likely to know.
Impressive, we need more true engineers like this!
Deep respect for the engineering of this project.
It probably has more preparation time than building time.
I couldn't be more impressed if it went into outterspace. Just wow. Had to watch twice.
Idk about that, ask that dude from star trek. 😉
@@leinadalan He's as old as this engine design and both still boldly going!
Wow, way to go Keith! This engine is an absolute work of art with all of the custom pieces and your touches on it.
It really is an art! He had to make colors that didn't exist and still made a cohesive working canvas to paint on! Pure delight to see the finished art in capable hands!
This engine is beautiful. The use of updated technology on a very old engine usually makes an interesting combination.
Stovebolts are quite simply 1/4 by 20 UNC bolts. Virtually universally used by cast iron stove manufacturers back in the day.FWIW, what we now call UNC was an engineering standard adopted by the US Navy in the late 19th Century.
Stovebolt Chevy engines use 1/4 by 20 fasteners as a default on valve cover and lifter covers and I believe the pan as well. Hardware store bolts can serve,but the GM bolts were better material than that.
My Dad - who was born in 1917 and grew up familiar with these 1927 < up engines - said that the fact that the flimsy cover for the oil pump itself was held on with these low strength, low precision machine screws was astonishing to mechanics used to engines having more precise and more expensive construction.
What you have to realize is that only truck and racing car engines had pressure-lubed connecting rod journals back then. Typically a splasher hooked under one rod bolt swung down and splashed oil everywhere inside the engine and some found it's way through a hole or two holes in the side of the big end of the rod to lube the crankpin. If you ever work on one of the very old design Wisconsin THD or TJD upright twin cylinder industrial engines you will see a much shorter splasher formed as part of the con rod cap - with an oil feed hole right above it.
The camshaft on those engines ran a simple vertical plunger-pump that picked up oil from the bottom of the pan and lifted it into small elevated troughs positioned so the short splashers could make contact with that oil.
That vertical plunger pump just lifted oil a few inches - there was no pressure as such. It's bore was made half in the block and half was a piece of tin bent into a half-pipe with ears. Stove bolt machine screws were good enough to hold the tin cover/half-the-plunger-bore to the cast iron block. (Surprising experienced mechanics of the day.
Hey Model T Fords used the oil splash off THE FLYWHEEL DIPPING IN THE BACK OF THE OIL PAN, and finding it's way by sheer chance into a FUNNEL AND PIECE OF COPPER TUBING to gravity - lube THE MAIN CRANKSHAFT BEARINGS.
Compared to that - the Chevy Six was much more modern !
@@patrickshaw8595 been a while since I've been in one of these , but if I recall correctly the dipper was a funnel that caught oil and forced it into the crank oil galleries . If oil was cold then it was to thick to be forced into the galleries , if you over revved it then the oil in the pan didn't have time to flow into the channel created by the dipper and it ran dry
I wonder if anyone from the 50s that designed those engines would have thought it would someday be producing 500+ horsepower.
Fascinated by straight six builds.
That engine is straight art work.
Thank you so much for sharing !
Cheers
This is the kind of stuff I enjoy watching . Taking OLD engines , and really tricking them with new stuff . THANK YOU FOR THE VIDEO .
this is what separates this channel from any guy with a junky ls, that engine was made just because it can be done instead of just using a stroker sbc. Congratulations that engine is truly unique
I wish I had 10% of this guys engine building knowledge
I am beyond happy, that someone actually built one of these! :D
Wow , that's incredible , just gobsmacked by the absolute perfection and creative genius of this builder. My goodness, that's well worthy of a Sema or on display with Jay Leno's on permanent displayed front and center . Please make sure to follow-up on this masterpiece
Impressive! Thats a lot to ask for that old chevy, but like what was said, this is what separated the true builders from the assemblers. Coming from a background in this stuff, this is an excellent build. Genius!
The old 235 and 261 are very underated engines I have owned and built several they are a lot tougher than many think .
A 100 year old straight 6 cylinder making that kind of torque and horsepower is freaking amazing. This man is an engine building genius. Can't wait to see the finished suburban. The owner sunk some serious $$$$ in this
I simply cannot believe how beautiful this build is! This man is one smart cookie.
That's awesome! Love the non mainstream custom builds!
Thats the most intense Stove Bolt I have ever seen.
Try see some brazilians 250ci 3gen
We make over 2500HP
When I was in High school ...the 60s...I had a friend who had a 39 Chevy...with a built 6cyl. It started as a GMC truck engine and took 4yrs to build. He did everything to it that was known in those days...balanced, blue printed, ported/polished head, big cam...and probably more that I didn't know about. Then he put headers and three 2bl carbs to top it off. It was the baddest car around. It beat anything and everything that came along. It was awesome! So I love seeing build like this one.
What a great idea! The ingenuity in this build is at the top of the tree for quality and professionalism!
Yet again you’ve put together a great video that never fails to impress anyone who watches it!
Thanks again HPM!! Love it!!!
Man I love seeing these oddball engines! I had no idea this existed
Keith is world class brilliant,one of the best there is or ever was....
About 10 different kinds of impressed. That guy knows how to get things done. The talent, innovation, and determination of this project just blows me away.
I'd give anything to have the 4.9 in my Econoline built up, I saw powerblock get 500 HP from one they built with a single turbo, not that I need that much power, I'd just like to have something to show off a bit, my 73 never reached show potential, it was a work in progress but was totaled out in an accident, I lost a fortune due to it being marked a no fault accident. I love the sound of a straight six engine, along with their durability.
This is what hot rodding is all about. Great vid
Thank you!
I really hope that air filter setup isn't permanent....
twin turbo itb stovebolt? holy crap!
I've always been partial to the Chevy flat 6. Would love to try one in a twin turbo variety. This straight 6 is insane. The main bearing trick scares me however. I'd never have the guts to do that.
Truly the godfather of engine builds. Genius. Impeccable work. Pa, keep kicking ass. One love. MA-
Very impressive, especially with just a 4 main crank. Later GM in-line 6s, and the Le Mans winning Jaguar XK engines all used 7 mains.
Exactly what I was thinking, only four mains plus that huge center double counter weight kind of bothered me but I guess at 5000 RPMs it won’t be too unhappy.
Awesome build! I love unique, off-the-wall engines like this👍👍👍
WOW! this is great. My first engine I rebuilt was a 235 CID. in 1966. Love this.
I’ve put together a few engines but this is a wholenuther level. Mechanical masterpiece!
I love the builds Keith does and this one is no different, my favorite was the V8 block turned into a V6 and he plugged the rear cylinder holes, he's the best engine builder too me but i may be biased since I live minutes from his shop.
This is the first time I've seen the man. I'm 62 years old, and I completely agree with you. Most people with his abilities are rather difficult to be around. I could hang out with him all day just to watch and listen
It’s good to see proper engineering is still alive. Awesome 🦴🦴🦴
Poke. My grandpa taught me that. And I quote. “Y’know, cause’ you poke around in it!” 🤩😂 god bless
Incredible how nice it looks, it's a piece of art, and the sound is like music. What an awesome build!
These Builders are our worlds Best, I hope we Never half to miss them. God Bless these Builders.
This is the best engine building channel on UA-cam.Without a doubt can't wait till the next video.
Wow! Thanks very much!
This Is a real engine build!
Beautiful engineering to an ancient engine design to bring in into the 21st century - respect!
I just love the unique stuff.
This is how to win "Best Engine" at ANY show.
I just love that old school sounds you are such an awesome inspiration to us all
KUDOS TO A TRUE INNOVATOR AND EXPERT ENGINE BUILDER. 👍✌
Cool to see people still keeping the olded six's alive. I've been running an old aussie GM inline six with a single turbo for close to 20 years
Thanks for the awesome video. I love the Chevy inline 6. I'm building a 292 with 6-71 blower, 2 Quick fuel 650 DP, Ryan Falconer V-12 head (aluminum crossflow 340I 220E), Crower billet crank, cam and rods, girdled and doweled mains, 5 stage dry sump and Electromotive direct fire coil over ignition. Going to keep it down to 1000 HP. It's going in my 53 Chevy 1/2 ton pickup with a Tremec 5 speed. I have electric P/S and an electric A/C compressor. I'm looking for 8.50 in the 1320. It's nice to see I'm not alone in my madness. I know 3 other guys running a little north of 1000 HP in their 292's, 2 with turbos and 1 with a blower. Thank you for your time.
Sounds like a fun build! Thanks for watching
Good luck, I hope it works.

That's some serious old dude knowledge and some serious Ingenuity that has been lost to time more of us need to be able to learn to do these things if we're going to be able to keep our passions of driving things fast going. I appreciate the hell out of this video I love the story and I love to see what people are doing in the world thank you for putting it out there
Sure he knows a lot of the past, and he did not get where he is without anticipating, adapting and embracing modernity and the future.
Keith has forgotten more about engines then most master mechanics ever learn.. what a legend
I was glued the whole video 👀 WOW hundred year old beauty 👍🔥and I'm not even a motor guy😂
Wow the attention to detail. Even the accessories on the front look perfect.
What an awesome build! Such a great example of craftsmanship! Looking forward to the next one!
This is all genius work. You won't find this much of anywhere but here, on this channel. Awesome engine build and I would say the best straight six build to date. It trumps all of them. Too bad it only cost a million dollars though 😂👍
Those builders are a rare breed ☝️😎👍
Totally awesome build. I was literally glued and I was even talking to my wife on the phone about a lot of the lower end portion of the build. It just took over my mind! Brilliant stuff.... Thank you for putting not only the amazing engine together, but the masterful presentation as well... Both equally impressive in their own rights.... WOW!!!
Thanks a lot!
This was a very impressive build. My absolute favorite so far.
thanks!
I moved from the US to Australia in 1976 and discovered that straight 6 engines were the rule here and V8s relatively rare. But General Motors Holden was the car maker that was by far No 1 for Australians. Since it went it’s own way after the 1948 Chevrolet, GMH had used the Grey 135 CID straight 6 and then up graded it to the Red motor in the mid 60s which by the time I arrived had been increased in many steps to 202 CID. There was also heaps of aftermarket go fast gear for the Holden 6. I recall looking into the window of a hot rod shop at some Yellow Terror heads. Yup, they were painted bright yellow. So this build taking a 50s block and throwing everything we have learned in the last 70 years at it was really enlightening. More than anything else it shows exactly what computer technology is worthwhile putting on an internal combustion engine. No check engine light. No significant other sensor. If I were building up a straight 6 on a budget I would upgrade the engine for economy, not power, given current conditions. I’d start with any decent body that would easily accept a GM straight 6, and go as far as money,common sense, and my own skills would allow. Way less than those of a master builder, but what a stunning example of what is possible. Thank you for an excellent video.
I enjoy these non-cookie cutter builds. Everybody swaps a small block or an LS.
Awesome build! Makes me want to do an overhead cam Packard straight 8!
My favorite notifications always come from this channel 👍👍
Thanks a lot! And thanks for watching!
This isnt just an engine, this is f###### art! Awesome job!
This is mind boggling! 😳
Wow! Such incredible engineering! 😮
A true engine building genius. I wonder how many he has put together with that old torque wrench he uses. If that thing could talk, man the stories. Great video..
Blown Straight sixes are a throwback to the old 50-60’s Railcars that were running 8’s and sometimes a lot better.
This is a really cool build. Not just another LS. All the work arounds are genius.
Wow, this is old 6 next level ,, great build for sure.
