We had a 66 impala SS with all original papers. It was listed as 275hp with single exhaust, if dual exhaust it was 300hp. Using this paperwork and many other sources this engine had the "300hp" cam which would later be used in the l48 350's of the 70's. I know this is an old video but Nick's Garage is historical documentation for furure generations!
Back in the 70’s I had a ‘68 Camaro SS with the 327 and 2:73 rear end. It was white with a black nose stripe, black vinyl roof and red interior. The tires were BFG T/A’s on aluminum slotted wheels. After graduating from college, my buddy and I drove it from Hamilton to Vancouver to LA and back in the span of 6 weeks. We didn’t have one hiccup with that car. I sold it in the early ‘80’s and have regretted it ever since.
hello I had a n68 white with black nose strip rs hideaway headlights RS. 327 three speed. that car was the best i also have regretted ever since selling it. The engine i of cousrse rrebuilt high performance hooker headers side pipes so cool..Black vinyl top also so cool
Had a 68 malibu 2dr with a 327 275hp with a powerglide. I was in the Navy in 1976 and drove the wheels of that car. Nice smooth driving car. sold it to by a 69 ss396,350 horse 4spd. wish i still had both!
i grew up on my daddy's used car lot on the 60s-70s i got to drive and own a lot of cars. i became a professional transmission rebuilder and shop owner. i retired 2 years ago but still build a few now and then. i have a super nice 1986 monte carlo ss it is painted cyber grey,,,,,,,,,,,,,,,,,,,,,,
My first muscle car experience was age eleven in 1966 when my brother came home on leave with his new ‘66 Chevy II, 327 350hp. One power shift and I’ve been hooked on cars ever since that time. Have a great week everyone
Those little Chevy II's would blow your mind with a 327 with cast iron manifolds. I'm a big block man, but I knew those little cars were something that could ruin your day. Lol
@@BuzzLOLOL It got the 302 which was is based off an even hotter 327 the L74, just with a 283 crank. The L79 would be stroked and became the L46 350/350 exclusive the Corvette. That Chevy parts bin isn't as big as most often think. The L79 was the solid lifter short block and heads(2.02) with a decent cam vs the plebeian standard 4bbl cam. The challenge Chevy had was the SBC didn't have great flowing heads so they leaned on the cams so rougher running more stall prone mills if they wanted power. You don't see the first decent factory head until '71 on the LT1 350. Perhaps over looked is that it introduced the 350 exclusive to the SS350 Camaro in '67, that stroke and more importantly the extra torque was something felt in every test drive. So much that with similar gearing it matched the 302 in acceleration at least until the headers and slicks went on.
@@Dayandcounting - The first Chevy 302" were the '301's we made by overboring a 1950's 283... The small, light. streamlined '67 Camaro really should have had the L79 as its top engine option... but that would have been too much power/speed too soon for GM... and the rear suspension would have had to been better from the start... also, like the Fiero, Camaro was prolly first sold to GM as an 'economy' car... LOL! Chevy heads didn't flow bad for the time... a little 327 with 4 bbl. carb., base level cam, and 10:1 made 300 HP... everybody else back then needed lots more cubes to make 300 HP... Chevy's base 1.94" intake valves were bigger than Pontiac's hyper 1.92" intake valves... eventually everybody's small blocks got up to Chevy's hyper 2.02"/1.60" 'Fuely' valve sizes... except the Ford Windsor engines...
I did the same - Built a 327 for my truck. I was pretty surprised that with a small cam with 204 @.050 intake duration, the 327 still is happy at higher RPMs. Headers +.060 overbore - decked block - smogger heads - Quadrajet It's fun - Not octane sensitive at all... Bout 8.5:1 CR
My first car/truck was an '83 S-15 GMC pickup. It had a 2.8L V6 in it. It let go one day after about 173K miles, and the truck just sat. A buddy of mine had a 327 sitting around out of his dad's long-gone Corvette (not sure what year since I was just a kid, and not sure what trans it was bolted to). We decided to force it into my old truck one day. It took a couple of high school summer weeks, but we got it running pretty good. The fun didn't last too long. After a few pulls and his dad helping us tune the carb (I think it was a 4bbl Edelbrock) , our home-shop mods to the drive shaft let go. The fun ended there, but what memories. Knowing what I know now, with the resources I have....that would/could have been sooo much more fun....and probably trouble, for a youngster. LOL
I had a 68 Chevelle with a 327 with a rock crusher 4 speed. I bought it from my uncle it was red with black interior. I put a factory cam in it OEM 375 horse Corvette Cam a dual point distributor with a mechanical drive tach a set of Hooker headers and a 650 Holley spread bore with mechanical secondaries and man that car was the fastest car in town all anyone ever saw was tail lights 💯💪. Boy I sure miss that car
I had a rebuilt 283 . The guy that rebuilt in 1972 was Les Stadel . Not that much power. But soo balanced that we never did accidently blow it up. 2 clutches though. Best little motor ever.
My brother had a 1967 Chevy II with a 327 4 speed back in the mid 1970's. I got the car from him around 1985. It had the small journal 327, it took 11/32 rod bolts and smaller rod and main bearings. I know that I would get some weird looks sometimes when I'd tell people that it had the small journal 327 in it. It had a front sump oil pan too! It took its own special oil pump, pick up tube and oil pump drive because of the front sump oil pan. Wish I still had it! My brother wishes that he would have kept it too!!
I'm 53 now, but when I was 17 I bought a 66 impala ss for 800dollars. Being young and crazy the first thing I did was put a Holley 4barrel and headers. Bullet mufflers. The car had double hump heads and ran like a scalded dog for a led sled. It was rusty ,primer fenders and a grey rebel flag with stars in primer on the roof. It was supposed to be 325 horse. The carb and headers really seemed to work good. Great video sir.
Nick , you made my day by sharing your first car story that involved your dad . My dad bought me my first car too . It was a 66 Rambler American 440 convertible.
My Grandfather had a '64 Impala SS ,triple black ,327 .Bought it new . I loved that car , first time I went over 70 mph was in it . I guess I was about 10 or 12 years old .When he mentioned to me that he was planning on trading it in I begged my Dad to buy it . His response was "I can't afford that car". That was 7 or 8 years after my Dad sold his '55 bel air to buy our house . That apartment wasn't that bad .
Nick, in 1968, my dad bought a '68 Impala 2 door with a 327. Loved that car! When I turn 16, he let me drive it ONE time! I ended up with a '64 Dodge 330 as my first car! I wish I still had it! It would be a great build today with a 426 Wedge !Bill from Linglestown Pennsylvania
Be proud George. 327 was the motor everyone on the street tried to beat. My 2 best motors DZ 302 n a 327 with double hump heads. 25HP is about right for header gain.
Hey Nick great video. During the mid 70’s I had two 67 and one 66 Chevy ll. One was a wagon that was a 6 banger and 3 on the tree. My dad and I found 327 and 4 speed that we removed from a wrecked 63 Corvette. What a sleeper that was.
My granddad had a 283 in a 67 Chevy pickup with the front fill breather he was constantly replacing the Crome cap. I put a block off on and got 350 style valve covers with the breather on the covers never had another problem.
Back in 66 my brother bought a 65 Impala SS, 327/300HP, 4 speed with a posi. He was worried it would get stolen. He took off the 327 badges and replaced them with 283. That was a very nice car. Very fast.
My friend in high school had a 65 Impala with a 327, 4 speed, posi. But, that was 1988, the elements were not being nice. The rear springs ripped off the frame about the time he dropped the clutch in 3rd gear, rolling about 40-50mph. What ensued was the longest, most amusing crash I’ve been involved in. Seems like it took a full minute for it to spin all the way around in two lanes and median, grass flying around, him cursing and fighting that massive steering wheel
@@jgriffin7340We'll put that down as things that didn't really happen on the internet. One eould have to rip one of the control links out of the frame to have a spring come out .
@@MUUKOW3 That is correct, the lower control arm mount on the right side pulled out and allowed the rear end to move back on the right side enough to bind both rear tires against the body.
In 1962 I ordered a new Impala with a 300 hp 327 and 4 speed. I ran at the local drag strip every Sunday. It came with 2.5 inch exhaust with the rams horns manifolds and I had open exhaust dumps welded on. I put on a set of Hedman headers and made no difference at all in et's or mph. Some rams horn manifolds were smaller though. I won 23 trophies with that car and it was legally stock and had a blast with it!
That is good to hear. My 66 Impala only has a 283 but I recently built it 30 over with about the same cam, 500 lift only difference. I got a smoking deal on some rebuilt 80s 305 H.O. heads that gave me bigger valves and higher compression, not to mention OEM hardened valve seats. I still run the ram horn manifolds and that allows for the stock alternator mounting. I did block off that down draft tube and went with a PVC setup. I'd like to see if you incorporate a PVC and still keep those valve covers.
Good move - which version? The usually used ones were a 2" outlet, the 'Vette versions used a 2 1/2" outlet and are generally the ones to go for. I think most repro' stuff is the latter.
I love the video you made and stated " 400 small block , not a very popular motor" The 400 sbc only paved the way for the 434 ,377,and 383. . And the Oldsmobile 350 build was hilarious 400 hp was a modest number for that one. Let's not even talk about the 455 stage 1 Buick , laughable man. keep the funny vids coming.
@@davidsnova 400 SB was a unicorn. It sucked. Everything you described was because they only used the block. Nick has forgotten more about engines than you'll ever know, troll
Nick I had a 70 barracuda red on red back n the late 80s just a 318 904 car ps/ac/am/fm car 4wheel drum brakes....only car iv ever regretted letting go .
Hi Nick it's Shawn from South of the Border here in Burlington Vermont. I just wanted to let you know that 327 is my favorite Chevy small-block engine. My friend had a junkie 78 Camaro that had the Carolina squat but it had a 327 in it and he had done some work to it I don't know what he did to it but that thing would rev and rev and rev forever and believe it or not we had his Camaro doing over 140 miles an hour with that little 327 in it
Still have one in my Nova. I am restoring it and many are suggesting I go with something larger. It was originally a straight 6 so I wouldn't be hurting the originality of it. That little 327 is very responsive though.
I have a little LS 4.8 in my ‘73 c10…all it has is a 220/220 cam and matching higher lift springs with hardened pushrods……I can spin that thing all the way up to 7300 rpm with no problems…..now with that said I’m getting ready to bolt on a centrifugal supercharger……woohoo!!!………and yes had you been able to buy that ‘67 Chevy 2 back in ‘73 with your father , I and 95% of your subscribers could promise you that you’d definitely be a Chevy guy!!! Awesome story by the way!!!
I love the way Nick has so much care for the engines on his dyno. Checks for oil leaks, brings them up to operating temperature and makes sure everything is fine before running them up.
One of my girlfriends had a red 327 Chevy like the one being worked on today in your shop. We had a lot of fun with that Chev and this upload certainly brings back memories. I was always pleasantly surprised how fast the little 327 would wind up. At the time I was driving my 440 Roadrunner and power-wise there was no comparison but I certainly liked the fast-revving Chevy. Her brother owned a service station so the cars were always kept in tip-top mechanical condition! She was great behind the wheel, too......that gal could run with the best of them!! P.S. Anyone who does rewiring deserves a medal for patience and it sure isn't me! I never really cared for the spread-bore Holley on the Chev and felt I could fine-tune the Quadra-Junk to give me sharper response and better mileage........but, what the hell; let's see what she'll do. No way would I give away the torque/hp that those restrictive manifolds produced. I think that ram's horn manifolds might get a bit of it back.......dunno.... P.S. The color on the Charger 500 is beginning to grow on me........
This man knows what he's doing. Once an engine is up temperature, retighten the header bolts too compensate for expansion, will save you fixing leaks later on!!!
I had a '70 Cuda, blue on blue, white rag top. Nice car! I wanted the Hemi, with the shaker, but I ran out of cash & had to settle for the 383. My first new car, I was 17!
I wonder if a set of 2 1/2" "ram's horns" manifolds would have done better than the stock manifolds you used. I'm pretty sure the 2 1/2" were used on the Corvettes for quite a few years
I agree. The rams horns, especially the 2 1/2" Corvettes flowed better than the later manifolds. In fact, his 66 Impala would have had rams horns on it from the factory.
Absolutely, we ran those in oval track racing for years, because the rule required factory manifold's... Now, send them to brazinski to be hogged out and flowed, I'll put them up against ANY aftermarket header.!!
In 76' my parents split up, my dad bought my mom a 67' 327 RS Camaro blue with a white convertible top. I really liked that car. The 327 was plenty of power & seemed to break down. Mouse 🐁 motor. It had a white stripe around the front & hide away headlights. 😲 Wow who would Expect muscle & pony cars to be so hard & Expensive to get! Can you believe it Nick!
Thanks Nick and George ! Ive had a 327 .030 over for years and i love it !! solid isky and 202 camel hump heads, 600 holley.... had headers but i swapped back to manifolds several years ago ... i knew it slowed a bit down but its still a fun ride in my 64 malibu.... thanks for the dyno numbers as i thought mine was always in the low 300 hp range ... happy greek easter too
Yip, i love my little steel crank 68 327, last ran 20 years ago, being built to an old school recipe, using a NOS moon circuit cam, offy ram, 650dp spreadbore, 462s, and powerglide. Heads, crank etc are the engines originals.
just a thought... do you have the rear crank case vent blocked ? Its jsst a hose to the ground then in 67 they routed it to the air cleaner ... thanks again👍
The 327s that I had were full race Nascar type. 7 grand every gear. All cast iron too Gas guzzlers but GO GO GO. Man did they sound sweet with header 3 1/2 inch collectors an H pipe @4"back then a 1 3/4"x12" opening at the end of exhaust on a 45 degree angle setup with a taper out from the H pipe. 1968 Camaro Group IV. 4 speed trans. I did one season with it. Very good engines.
I had a 68' 327" 275hp on the factory Air Cleaner. In a full size Caprice Estate Wagon. Hideaway headlights, power everything. Headlight, Highbeam, and turn signal indicators on top of the front fenders. GREAT CAR!
I've had several 327 motors in my 60 years and found this motor to be very responsive and almost indestructible one of the best motors Chevy made I wish like alot of us older gear heads say had the cars back that just them motors were in
My first vette a 65 327/365 four speed with 4:11. So much fun and 0-80 through the gears was always fun. They were like little race engines and sounded like it. Some of GMs finest days back then.
When big blocks were reigning the race car scene at the dirt tracks we blew ours up one of our friends with the pitcrew had a 69 chevell with a 327 in it and we jerked the motor out of it and installed it in the stock car and went out and won the feature with it , and it sounded like a bumble bee against those big blocks but it was funny 😳 👍
Nowadays BB Corvettes are bringing big money. But the Corvette was never designed for a BB. The SB was much lighter so handling was much better with less weight on the frontend. Properly tuned a 327 didn't give all that much away to the BB of the time. I was sad to see the 327 go away.
The very fine 327 small block from its small block family: 265, 283, 327, 350, 400. We also had 302 (Z/28) and 305 (garden variety). Now you can get a 377 from Mercruiser! The small block lives on!
@@basilcarroll9729 You’re right there was the 307 & 305 small blocks which were standard on many Chevrolets, the 307 I think replaced the 283 and the 305 came along later like when the full size and mid sized cars were down sized in 1977/1978.
The GM 327 was used in many things cars..trucks..even farm equipment! I seen one in a combine..a welder..a water pump. Even air raid siren! Great engine for its time.
Hello Nick and George!!! Very cool to see the Chevy Impala getting a new lease on life . Very good to have a wiring man who knows his stuff . That's a beautiful 327 engine , beautiful color and paint job on it . Be nice if they stay that way ...lolololol. Love hanging out at Nick's Garage ..
EVERYTHING starts with an idea .Then a clean sheet of paper. Then the pens are laying down the ideas .Hen the foundry sand moulds are made Then the castings are poured. Then they are cured .Then they are machined, fitted with crankshafts, pistons & Rod assemblies, camshafts ,heads,pushrods,Oil pump and intakes carbs,and fineally oil pan ,valve covers,timing chain cover ,harmonic balancer and pulleys belts,air cleaner . AND VOLLÀ .One sweet running little engine .
Nick, you must have good oil in your veins to remember all those facts and figures and stories from your past ! Well done its a pleasure to watch a master in action.
It’s amazing how this thing sounded when you fired it up. It sounds exactly like mine. Very similar set up. And yes we’re running cast iron manifolds. Great job Nick!
Another great video! The double hump heads look like 461s, 194/150 valves..cool! Original GM exhaust manifolds never used gaskets, it was a metal on metal fit and they never leaked. I also thought maybe in 66 an oil baffle was under the intake and the PCV was in line from the base of the carb to a port at the back of the block. Nick's videos are awesome!!
Mopar big blocks other than some trucks never used exhaust gaskets either. Best way to go! Surface them flat, use a SMALL amount of rtv and antiseize the bolts with hardened washers and torque to NO more than 15ftlb. No warping, the hotter manifolds can move relative to the heads and metal to metal heat transfer. I know pro builders that Surface headers, cut the bars between the ports and toss the gaskets. (Copper or SS does work well on imperfect flatness tho) First thing you did on a big block international plowing snow! Unless you liked changing 3 sets a year and a huge pile of scrap cast iron in the shop! (The next two were to drill out the jets and crank the timing around to where it ran good!) Amazing how many stubborn people can't wrap their heads around this and warp manifolds and twist off bolts trying to hold them.
Also. I always use copper on headers and always use at least a 6" high quality piece of flexible exhaust just behind the headers. This is especially important with bigger diameter systems because the pipes are so rigid they torque the headers HARD and will take out gaskets and Crack header tubes from engine motion and expansion. My headers and gaskets have so far lasted 3x longer with my 3.5 to 4" system this way.
No better way to spend a very wet and stormy Monday. The rain is really coming down on DelNorte CA but it doesn't seem so bad when Nick is Dyno testing a customers engine on You Tube.
The little engines that could... 327 Chevys, 273-4bbl Mopars, 289 Fords... always liked how the little engines ran putting out way better performance than you'd suspect for the cubic inches.
318's and 340's were way better engines than the 273. Only thing good from a 273 was it was reliable. It couldn't make power even if you paid it. That's why it would run forever. It couldn't produce enough compression to blow up.
Nick, when you talk about the Chrysler Dealership on Decarie, was it called Chrysler Trans Island, near Snowden. I also remember Harold Cummings across from Blue Bonnets in the late 1970s. I was just about 10 years old, back then. Lol! Thank you very much for this magnificent presentation. Johnny, Montréal. 🙏😉👍✔️
I took a 327 out of a 1968 Impala, had it rebuilt, and put it into my 1978 Caprice. The 2.56 rear gear killed the performance. But after it got going, there wasn't much that could touch it.
Hey Nick , me and the Chevy Impala a 1966 to be exact have a Love - Hate Relationship....back when I was growing up ,in 1969 . I came out of my neighbor's driveway on my Firestone GTO bicycle, not looking and got hit by a red 1966 hardtop Impala with a Mom and her kids right after school , she was running about 35 mph .. Luckily I hit on the right side of the front highlights & hood . Well....me and the old GTO Bike went over the hood ,came down the passenger side ...I took the passenger mirror off with my back , when I hit the mirror ,it shot me and my bike about 25 feet into the driveway I came out of ...talk about rocket man ...The mom slam on brakes, stopped ,got out all upset ..Again my Guardian Angel was working overtime .. I came out with a bad bruised back , skinned up knees, hands ,and legs. No broken bones ,or any other injuries...So ever since then I have a high Respect for 1966 Impala's ...It's a true story .. my ol GTO bicycle was no worse the wear ...later in 1978, I got a 1970 Red GTO with black interior, tac on the hood and RAM AIR 400 ....Those were the days ..10 feet tall and bullet proof .. lolololol...love your channel Nick and George...God Bless .
Needs more crankcase venting, @20:30 it pushes the filler cap/vent off the filler tube, back when I was racing a 327 in a stock car I had 4 vents, 2 tubes in each valve cover topped with breather/filler caps for a big Chrysler, no such thing as too much ventilation.
I like the ram horn factory exhaust manifolds. I had a 327 from a 69 impala with 2 barrel carb, turbo 350 trans. put it in my 60 chevy station wagon. worked very nicely for family car/boat puller. peanut carter was president and 55mph speed limit. my car would do 20mpg at 55mph and I was happy with that.
We bought a Cordoba in 1975. 440 was still available. 318 was a no cost or credit. I tryed to get mom to go for the 400 4bbl w duals. No Cats on Chrysler in '75 like GM. Mopar got them in '76
One thing to note to the owner: find a set of plug heat shields to use with the manifolds. Those log manifolds will cook the plug boots without them---I know from experience. Vette rams horns with angle dumps might fit and give better performance. They have 2.5 inch outlets. Those old Impalas used rams horns so they should fit OK. Older blocks had the road draft tube at the back of the block next to the distributor. California emissions had PVC valve mounted in that hole instead of the road draft tube. "Later" (relative term) blocks lost the hole in the rear and needed the hole on the valve cover. Frequently people would put a freeze plug in the road draft hole on early blocks and use vented valve covers. Oil fill and breather intake stayed on the front of the intake until 1969 when the inlet went to the opposite valve cover. That made sure that the vapors were pulled from one side of the engine to the other.
A friend of mine had a early 4 speed Nova with the carbureted L76 327 365 hp.The car surprised me ,in that the the engine felt much bigger than it was.If he had told me it was a 396 375 hp I would have believed him.
Your friend may have had the available L79 350 HP 327" hydraulic lifters engine that ran about as well as the L76... get it up to 2500 RPMs and it 'came on the cam' and exploding into HP !!! The little 3 valve 280" V8 in 2006 & up Mustangs also is surprising and feels like a big block engine!
Chevy did make a cast iron performance exhaust manifold for the 327 it as called ram horn exhaust manifold and the manifold’s you have on the 327 now are the smog pump type from the 70s had them on a Camaro and a Monte Carlo !!!
I had a 70 Camaro I bought new and in less than a week the valve covers were leaking. I changed the valve cover screws and they were no more than finger tight. I tighten them up but only slowed it down. My experience is when corke gaskets start leaking there is no stopping it . I replaced them with neosporin gaskets and worked perfectly.
I remember my uncle, who lived in Longueuil, had a 1966 Impala SS 396 convertible, dark red with a white interior (new). That thing was fast for it's time. There was also one in Laprairie, exactly the same, but with a 327. It was a beautiful car and it rode as well as it looked, especially with the top down. Best Regards - Mike
I would like thank everybody for there comments, and did get the ram horn exhaust manifolds
Thank you everybody
Beautiful car !!!
Awesome you won't be disappointed for getting them
Thank you
Good old ram horns 🐏 🔥 I like the ramhorns that slant back on a 45 😎
Think you would like 2 sizes smaller cam... this race cam miserable for a cruiser...
We had a 66 impala SS with all original papers. It was listed as 275hp with single exhaust, if dual exhaust it was 300hp. Using this paperwork and many other sources this engine had the "300hp" cam which would later be used in the l48 350's of the 70's. I know this is an old video but Nick's Garage is historical documentation for furure generations!
Back in the 70’s I had a ‘68 Camaro SS with the 327 and 2:73 rear end. It was white with a black nose stripe, black vinyl roof and red interior. The tires were BFG T/A’s on aluminum slotted wheels. After graduating from college, my buddy and I drove it from Hamilton to Vancouver to LA and back in the span of 6 weeks. We didn’t have one hiccup with that car. I sold it in the early ‘80’s and have regretted it ever since.
One of the prettiest cars ever made in my opinion.
hello I had a n68 white with black nose strip rs hideaway headlights RS. 327 three speed. that car was the best i also have regretted ever since selling it. The engine i of cousrse rrebuilt high performance hooker headers side pipes so cool..Black vinyl top also so cool
My Great Aunt had a 275 hp 327 in her 1967 Impala, man was that thing smooth.
67 first year quadrajet car.
Had a 68 malibu 2dr with a 327 275hp with a powerglide. I was in the Navy in 1976 and drove the wheels of that car. Nice smooth driving car. sold it to by a 69 ss396,350 horse 4spd. wish i still had both!
i grew up on my daddy's used car lot on the 60s-70s i got to drive and own a lot of cars. i became a professional transmission rebuilder and shop owner. i retired 2 years ago but still build a few now and then. i have a super nice 1986 monte carlo ss it is painted cyber grey,,,,,,,,,,,,,,,,,,,,,,
My first muscle car experience was age eleven in 1966 when my brother came home on leave with his new ‘66 Chevy II, 327 350hp. One power shift and I’ve been hooked on cars ever since that time. Have a great week everyone
The '67 Camaro cried out for that engine, too bad it wasn't an option...
Those little Chevy II's would blow your mind with a 327 with cast iron manifolds. I'm a big block man, but I knew those little cars were something that could ruin your day. Lol
@@BuzzLOLOL It got the 302 which was is based off an even hotter 327 the L74, just with a 283 crank. The L79 would be stroked and became the L46 350/350 exclusive the Corvette. That Chevy parts bin isn't as big as most often think. The L79 was the solid lifter short block and heads(2.02) with a decent cam vs the plebeian standard 4bbl cam. The challenge Chevy had was the SBC didn't have great flowing heads so they leaned on the cams so rougher running more stall prone mills if they wanted power. You don't see the first decent factory head until '71 on the LT1 350.
Perhaps over looked is that it introduced the 350 exclusive to the SS350 Camaro in '67, that stroke and more importantly the extra torque was something felt in every test drive. So much that with similar gearing it matched the 302 in acceleration at least until the headers and slicks went on.
@@Dayandcounting - The first Chevy 302" were the '301's we made by overboring a 1950's 283... The small, light. streamlined '67 Camaro really should have had the L79 as its top engine option... but that would have been too much power/speed too soon for GM... and the rear suspension would have had to been better from the start... also, like the Fiero, Camaro was prolly first sold to GM as an 'economy' car... LOL!
Chevy heads didn't flow bad for the time... a little 327 with 4 bbl. carb., base level cam, and 10:1 made 300 HP... everybody else back then needed lots more cubes to make 300 HP... Chevy's base 1.94" intake valves were bigger than Pontiac's hyper 1.92" intake valves... eventually everybody's small blocks got up to Chevy's hyper 2.02"/1.60" 'Fuely' valve sizes... except the Ford Windsor engines...
@@BuzzLOLOL The top engine was the solid lifter 396 rated at 375hp (420hp actual). The '67 also came from the factory with a traction bar.
A classic Chevy is a classic American car and you really can't beat red on red. Thanks for showing this beauty Nick.
Thanks Steve.
Started putting together a 327 out of parts I've had since 1981, better late than never.
Right on. No time like the present.
If it's a street driver, don't go as big a cam as used here...
Double hump heads are worth 50 hp
I did the same - Built a 327 for my truck. I was pretty surprised that with a small cam with 204 @.050 intake duration, the 327 still is happy at higher RPMs.
Headers +.060 overbore - decked block - smogger heads - Quadrajet
It's fun - Not octane sensitive at all... Bout 8.5:1 CR
@@BuzzLOLOL go away bud lol not getting the attention you crave here... We get it . You look your cars slower and less aggressive sounding .
My first car/truck was an '83 S-15 GMC pickup. It had a 2.8L V6 in it. It let go one day after about 173K miles, and the truck just sat. A buddy of mine had a 327 sitting around out of his dad's long-gone Corvette (not sure what year since I was just a kid, and not sure what trans it was bolted to). We decided to force it into my old truck one day. It took a couple of high school summer weeks, but we got it running pretty good. The fun didn't last too long. After a few pulls and his dad helping us tune the carb (I think it was a 4bbl Edelbrock) , our home-shop mods to the drive shaft let go. The fun ended there, but what memories. Knowing what I know now, with the resources I have....that would/could have been sooo much more fun....and probably trouble, for a youngster. LOL
I had a 68 Chevelle with a 327 with a rock crusher 4 speed. I bought it from my uncle it was red with black interior. I put a factory cam in it OEM 375 horse Corvette Cam a dual point distributor with a mechanical drive tach a set of Hooker headers and a 650 Holley spread bore with mechanical secondaries and man that car was the fastest car in town all anyone ever saw was tail lights 💯💪. Boy I sure miss that car
I got the 3/4 race cam it was called.... ran like there was no end.
I had a rebuilt 283 . The guy that rebuilt in 1972 was Les Stadel . Not that much power. But soo balanced that we never did accidently blow it up. 2 clutches though. Best little motor ever.
Perfect engine for a cruiser. Well mannered, not too choppy, just the right amount of power.......and it sounds so nice.
Nopers, cam is about 2 sizes too big for that engine, torque too peaky...
My brother had a 1967 Chevy II with a 327 4 speed back in the mid 1970's. I got the car from him around 1985. It had the small journal 327, it took 11/32 rod bolts and smaller rod and main bearings. I know that I would get some weird looks sometimes when I'd tell people that it had the small journal 327 in it. It had a front sump oil pan too! It took its own special oil pump, pick up tube and oil pump drive because of the front sump oil pan. Wish I still had it! My brother wishes that he would have kept it too!!
I'm 53 now, but when I was 17 I bought a 66 impala ss for 800dollars. Being young and crazy the first thing I did was put a Holley 4barrel and headers. Bullet mufflers. The car had double hump heads and ran like a scalded dog for a led sled. It was rusty ,primer fenders and a grey rebel flag with stars in primer on the roof. It was supposed to be 325 horse. The carb and headers really seemed to work good. Great video sir.
Oh wow...327...don't see many of those any more...can't wait to watch this!!
That Impala's owner loves that car and spoils it just like he would a girlfriend. Just different jewelry. True love like that never dies.
Congratulations on 200,000 subscribers Nick and George.
Thanks!
I owned a 1966 Chevrolet Caprice with a big block for 37 years. Times changed, had to sell it. Looking at this Impala, kinda bitter sweet.
Nick , you made my day by sharing your first car story that involved your dad . My dad bought me my first car too . It was a 66 Rambler American 440 convertible.
Great show Nick that 327 screams.A friend had 327 in 67 chevelle with 4.88 in the rear that thing was a monster.
I've been watching your videos since the first 5 videos
My Grandfather had a '64 Impala SS ,triple black ,327 .Bought it new . I loved that car , first time I went over 70 mph was in it . I guess I was about 10 or 12 years old .When he mentioned to me that he was planning on trading it in I begged my Dad to buy it . His response was "I can't afford that car". That was 7 or 8 years after my Dad sold his '55 bel air to buy our house . That apartment wasn't that bad .
Yeah, gotta sacrifice for the car you want... LOL !
Nick, in 1968, my dad bought a '68 Impala 2 door with a 327. Loved that car! When I turn 16, he let me drive it ONE time! I ended up with a '64 Dodge 330 as my first car! I wish I still had it! It would be a great build today with a 426 Wedge !Bill from Linglestown Pennsylvania
Thanks for sharing!
327 396 my favorite engine's of all time.
Be proud George. 327 was the motor everyone on the street tried to beat. My 2 best motors DZ 302 n a 327 with double hump heads. 25HP is about right for header gain.
Hey Nick great video. During the mid 70’s I had two 67 and one 66 Chevy ll. One was a wagon that was a 6 banger and 3 on the tree. My dad and I found 327 and 4 speed that we removed from a wrecked 63 Corvette. What a sleeper that was.
Very cool!
Sweet combination. Had a 65 two door, Vette 327 & 4 speed. Ran 14.0 crossing the finish line in 3rd gear. Got 22 MPG too.
My granddad had a 283 in a 67 Chevy pickup with the front fill breather he was constantly replacing the Crome cap. I put a block off on and got 350 style valve covers with the breather on the covers never had another problem.
Back in 66 my brother bought a 65 Impala SS, 327/300HP, 4 speed with a posi. He was worried it would get stolen. He took off the 327 badges and replaced them with 283. That was a very nice car. Very fast.
Nice trick.
My friend in high school had a 65 Impala with a 327, 4 speed, posi. But, that was 1988, the elements were not being nice. The rear springs ripped off the frame about the time he dropped the clutch in 3rd gear, rolling about 40-50mph. What ensued was the longest, most amusing crash I’ve been involved in. Seems like it took a full minute for it to spin all the way around in two lanes and median, grass flying around, him cursing and fighting that massive steering wheel
@@jgriffin7340We'll put that down as things that didn't really happen on the internet. One eould have to rip one of the control links out of the frame to have a spring come out .
@@MUUKOW3 That is correct, the lower control arm mount on the right side pulled out and allowed the rear end to move back on the right side enough to bind both rear tires against the body.
I'm a mopar guy too, but I also have a Corvette. I like everything!
In 1962 I ordered a new Impala with a 300 hp 327 and 4 speed. I ran at the local drag strip every Sunday. It came with 2.5 inch exhaust with the rams horns manifolds and I had open exhaust dumps welded on. I put on a set of Hedman headers and made no difference at all in et's or mph. Some rams horn manifolds were smaller though. I won 23 trophies with that car and it was legally stock and had a blast with it!
Lucky to have been old enough for these cars and dury-cheap leaded hi-test. The caveat was the hated 'Nam-era.
After reading so many comments, my client has decided to order a set of Ram Horns manifolds.
Nick you really are the man nothing but respect Sir.
That is good to hear. My 66 Impala only has a 283 but I recently built it 30 over with about the same cam, 500 lift only difference. I got a smoking deal on some rebuilt 80s 305 H.O. heads that gave me bigger valves and higher compression, not to mention OEM hardened valve seats. I still run the ram horn manifolds and that allows for the stock alternator mounting. I did block off that down draft tube and went with a PVC setup. I'd like to see if you incorporate a PVC and still keep those valve covers.
Good move - which version? The usually used ones were a 2" outlet, the 'Vette versions used a 2 1/2" outlet and are generally the ones to go for. I think most repro' stuff is the latter.
I love the video you made and stated " 400 small block , not a very popular motor" The 400 sbc only paved the way for the 434 ,377,and 383. . And the Oldsmobile 350 build was hilarious 400 hp was a modest number for that one. Let's not even talk about the 455 stage 1 Buick , laughable man. keep the funny vids coming.
@@davidsnova 400 SB was a unicorn. It sucked. Everything you described was because they only used the block. Nick has forgotten more about engines than you'll ever know, troll
Nick I had a 70 barracuda red on red back n the late 80s just a 318 904 car ps/ac/am/fm car 4wheel drum brakes....only car iv ever regretted letting go .
We had a 1966 Bel-Air ,283 loved it totally awesome !!!!
Hi Nick it's Shawn from South of the Border here in Burlington Vermont. I just wanted to let you know that 327 is my favorite Chevy small-block engine. My friend had a junkie 78 Camaro that had the Carolina squat but it had a 327 in it and he had done some work to it I don't know what he did to it but that thing would rev and rev and rev forever and believe it or not we had his Camaro doing over 140 miles an hour with that little 327 in it
Ya gotta admit that the 327 was a freak , an anomaly and a legend . The creation of a genius gone slightly mad. Top 5 greatest ever.
Still have one in my Nova. I am restoring it and many are suggesting I go with something larger. It was originally a straight 6 so I wouldn't be hurting the originality of it. That little 327 is very responsive though.
@@craigdoriety9798 ya gotta keep the story going and watch the smiles people get when they see one again !
I have a little LS 4.8 in my ‘73 c10…all it has is a 220/220 cam and matching higher lift springs with hardened pushrods……I can spin that thing all the way up to 7300 rpm with no problems…..now with that said I’m getting ready to bolt on a centrifugal supercharger……woohoo!!!………and yes had you been able to buy that ‘67 Chevy 2 back in ‘73 with your father , I and 95% of your subscribers could promise you that you’d definitely be a Chevy guy!!! Awesome story by the way!!!
Cam used here is too big for the engine...
I love the way Nick has so much care for the engines on his dyno. Checks for oil leaks, brings them up to operating temperature and makes sure everything is fine before running them up.
Nice to hear some of your stories when you were younger! Especially how you got so involved in cars !👍👍
One of my girlfriends had a red 327 Chevy like the one being worked on today in your shop. We had a lot of fun with that Chev and this upload certainly brings back memories. I was always pleasantly surprised how fast the little 327 would wind up. At the time I was driving my 440 Roadrunner and power-wise there was no comparison but I certainly liked the fast-revving Chevy. Her brother owned a service station so the cars were always kept in tip-top mechanical condition! She was great behind the wheel, too......that gal could run with the best of them!! P.S. Anyone who does rewiring deserves a medal for patience and it sure isn't me! I never really cared for the spread-bore Holley on the Chev and felt I could fine-tune the Quadra-Junk to give me sharper response and better mileage........but, what the hell; let's see what she'll do. No way would I give away the torque/hp that those restrictive manifolds produced. I think that ram's horn manifolds might get a bit of it back.......dunno.... P.S. The color on the Charger 500 is beginning to grow on me........
Cam also looks too big and peaky for a street cruiser...
This man knows what he's doing. Once an engine is up temperature, retighten the header bolts too compensate for expansion, will save you fixing leaks later on!!!
I had a '70 Cuda, blue on blue, white rag top. Nice car! I wanted the Hemi, with the shaker, but I ran out of cash & had to settle for the 383. My first new car, I was 17!
I wonder if a set of 2 1/2" "ram's horns" manifolds would have done better than the stock manifolds you used. I'm pretty sure the 2 1/2" were used on the Corvettes for quite a few years
I agree. The rams horns, especially the 2 1/2" Corvettes flowed better than the later manifolds. In fact, his 66 Impala would have had rams horns on it from the factory.
Absolutely, we ran those in oval track racing for years, because the rule required factory manifold's... Now, send them to brazinski to be hogged out and flowed, I'll put them up against ANY aftermarket header.!!
Bingo! My thought exactly! Those junk manifolds killing that 327.
Yes those ram's horns manifolds flowed fairly well for stock manifolds
Yes I also ran circle track and rams horns flowed better so they were outlawed in stock classes as they made more power.
Congratulations on 200k subscribers.
Thank you!
Excellent quantitative data!
Headers even with their potential pitfalls are worth it to me. Great video Nick
In 76' my parents split up, my dad bought my mom a 67' 327 RS Camaro blue with a white convertible top. I really liked that car. The 327 was plenty of power & seemed to break down. Mouse 🐁 motor. It had a white stripe around the front & hide away headlights. 😲 Wow who would Expect muscle & pony cars to be so hard & Expensive to get! Can you believe it Nick!
Nothing wrong with a small block chevy , great Monday Nick 👍
I just got the rebuilt 327 in my 67 Camaro running! It's hot as a pistol, sounds like an angry panther.
'67 Camaro cried out for the unavailable 350 HP 327" engine option!
My first car was a 66 Impala, 283 Powerglide. Love to have that one back
Had a '63 Impala convertible with a 327. Loved that car. Great video. Enjoyed the music choices!
Thanks Nick and George ! Ive had a 327 .030 over for years and i love it !! solid isky and 202 camel hump heads, 600 holley.... had headers but i swapped back to manifolds several years ago ... i knew it slowed a bit down but its still a fun ride in my 64 malibu.... thanks for the dyno numbers as i thought mine was always in the low 300 hp range ... happy greek easter too
Opa!!
Cool.
Yip, i love my little steel crank 68 327, last ran 20 years ago, being built to an old school recipe, using a NOS moon circuit cam, offy ram, 650dp spreadbore, 462s, and powerglide. Heads, crank etc are the engines originals.
just a thought... do you have the rear crank case vent blocked ? Its jsst a hose to the ground then in 67 they routed it to the air cleaner ... thanks again👍
Evenin Mr Nick!! Have a Great week!! U too George!! Just watched a replay of Friday's stream, awesome!!
Thanks! You too! Glad to have you with us.
When I see Nick in the control room it looks like someone in front of a mixing board creating sweet music ..👍😁

Always remember my uncles 67 Malabou, 327, four speed, tuned up. Used to surprise a lot of cars. Nice and light with plenty of snap.
Those Chevy valve covers are stunning - I love that font! That motor looks too good to run, like a piece of jewellery!
DJ Nick at the console - (Dyno Jockey) - vroom! 😎
The 327s that I had were full race Nascar type. 7 grand every gear. All cast iron too Gas guzzlers but GO GO GO. Man did they sound sweet with header 3 1/2 inch collectors an H pipe @4"back then a 1 3/4"x12" opening at the end of exhaust on a 45 degree angle setup with a taper out from the H pipe. 1968 Camaro Group IV. 4 speed trans. I did one season with it. Very good engines.
my favurite chevy motor,327/375 hp w 202 fi heads a real rat killer and quite afew fords &mopars!!!!!big blocks included!!!!
The 60's Impalas are so beautiful to me. In high school in the 70's, a friend drove his parent's Impala to school.
I had a 68' 327" 275hp on the factory Air Cleaner. In a full size Caprice Estate Wagon. Hideaway headlights, power everything. Headlight, Highbeam, and turn signal indicators on top of the front fenders. GREAT CAR!
that Impala is really RED! center dump manifolds with 2.5 inch flange probably a little better.
Mopar Man Forever Nick right on man
I've had several 327 motors in my 60 years and found this motor to be very responsive and almost indestructible one of the best motors Chevy made I wish like alot of us older gear heads say had the cars back that just them motors were in
My first vette a 65 327/365 four speed with 4:11. So much fun and 0-80 through the gears was always fun. They were like little race engines and sounded like it. Some of GMs finest days back then.
When big blocks were reigning the race car scene at the dirt tracks we blew ours up one of our friends with the pitcrew had a 69 chevell with a 327 in it and we jerked the motor out of it and installed it in the stock car and went out and won the feature with it , and it sounded like a bumble bee against those big blocks but it was funny 😳 👍
Nowadays BB Corvettes are bringing big money. But the Corvette was never designed for a BB. The SB was much lighter so handling was much better with less weight on the frontend. Properly tuned a 327 didn't give all that much away to the BB of the time. I was sad to see the 327 go away.
I had a 66 4 Door with a 327 with 283 power pack Heads with the 2 Speed Power glide! It would bark the tires at 70 shifting to Drive!✌️👍👍😀
Congratulations on 200k!
Thank you so much 😀
The very fine 327 small block from its small block family:
265, 283, 327, 350, 400.
We also had 302 (Z/28) and 305 (garden variety). Now you can get a 377 from Mercruiser! The small block lives on!
Don't forget the 307.
@@basilcarroll9729
You’re right there was the 307 & 305 small blocks which were standard on many Chevrolets, the 307 I think replaced the 283 and the 305 came along later like when the full size and mid sized cars were down sized in 1977/1978.
@@Luigi-pk8mk Yes, 1976 for 305 and 1979 for the 267.
The GM 327 was used in many things cars..trucks..even farm equipment! I seen one in a combine..a welder..a water pump. Even air raid siren! Great engine for its time.
Also the 225 HP Mercruiser marine 327 engine... and seen a 327 in a large telephone company bucket truck...
I got mine out of a short bus...
It’s awesome watching the secondaries open smoothly.
Hello Nick and George!!! Very cool to see the Chevy Impala getting a new lease on life . Very good to have a wiring man who knows his stuff .
That's a beautiful 327 engine , beautiful color and paint job on it . Be nice if they stay that way ...lolololol. Love hanging out at Nick's Garage ..
Thanks 👍
EVERYTHING starts with an idea .Then a clean sheet of paper. Then the pens are laying down the ideas .Hen the foundry sand moulds are made Then the castings are poured. Then they are cured .Then they are machined, fitted with crankshafts, pistons & Rod assemblies, camshafts ,heads,pushrods,Oil pump and intakes carbs,and fineally oil pan ,valve covers,timing chain cover ,harmonic balancer and pulleys belts,air cleaner .
AND VOLLÀ .One sweet running little engine .
Nick, you must have good oil in your veins to remember all those facts and figures and stories from your past ! Well done its a pleasure to watch a master in action.
George has a beautiful Impala, soon to have a nice cruiser engine too. Well done Nick. Stay safe guys, God Bless.
Thanks 👍
Cam looks too big and peaky for a 'cruiser'...
You can't compare this to an engine with a drivetrain and accessories installed!
But, I appreciate videos!
You can "compare" it... realizing the differences you may be adding... or not...
It’s amazing how this thing sounded when you fired it up. It sounds exactly like mine. Very similar set up. And yes we’re running cast iron manifolds. Great job Nick!
same here, old iron manifolds to keep it looking stock
Bon Jour/Good Day, nice to see the little "mouse" motor on the dyno.
This mouse roars!
Another great video! The double hump heads look like 461s, 194/150 valves..cool!
Original GM exhaust manifolds never used gaskets, it was a metal on metal fit and they never leaked. I also thought maybe in 66 an oil baffle was under the intake and the PCV was in line from the base of the carb to a port at the back of the block.
Nick's videos are awesome!!
always made me crazy there were no gaskets between the heads and manifolds
Mopar big blocks other than some trucks never used exhaust gaskets either. Best way to go! Surface them flat, use a SMALL amount of rtv and antiseize the bolts with hardened washers and torque to NO more than 15ftlb. No warping, the hotter manifolds can move relative to the heads and metal to metal heat transfer. I know pro builders that Surface headers, cut the bars between the ports and toss the gaskets. (Copper or SS does work well on imperfect flatness tho) First thing you did on a big block international plowing snow! Unless you liked changing 3 sets a year and a huge pile of scrap cast iron in the shop! (The next two were to drill out the jets and crank the timing around to where it ran good!) Amazing how many stubborn people can't wrap their heads around this and warp manifolds and twist off bolts trying to hold them.
Also. I always use copper on headers and always use at least a 6" high quality piece of flexible exhaust just behind the headers. This is especially important with bigger diameter systems because the pipes are so rigid they torque the headers HARD and will take out gaskets and Crack header tubes from engine motion and expansion. My headers and gaskets have so far lasted 3x longer with my 3.5 to 4" system this way.
yep your on it!
Next week’s episode is what Ive been waiting for 😎😎
No better way to spend a very wet and stormy Monday. The rain is really coming down on DelNorte CA but it doesn't seem so bad when Nick is Dyno testing a customers engine on You Tube.
Just washing the streets for better summer cruising.
The little engines that could... 327 Chevys, 273-4bbl Mopars, 289 Fords... always liked how the little engines ran putting out way better performance than you'd suspect for the cubic inches.
And they can take a beating.
318's and 340's were way better engines than the 273. Only thing good from a 273 was it was reliable. It couldn't make power even if you paid it. That's why it would run forever. It couldn't produce enough compression to blow up.
Don't forget the Studebaker 289 (not a Ford).
@@johnsonjeremiah74 - Hyper 273 had a snotty exhaust sound!
High compression 330 Olds!
Nick, when you talk about the Chrysler Dealership on Decarie, was it called Chrysler Trans Island, near Snowden. I also remember Harold Cummings across from Blue Bonnets in the late 1970s. I was just about 10 years old, back then. Lol! Thank you very much for this magnificent presentation. Johnny, Montréal. 🙏😉👍✔️
My 66 Impala convertible had the 275 horse 327 with Ram horn manifolds, I'm sure they breathe better than the smoggers you're running
Let's see some super-high revs from that little bowtie 327! Let's Go Nick! Hey George!
Wind it up!
I took a 327 out of a 1968 Impala, had it rebuilt, and put it into my 1978 Caprice. The 2.56 rear gear killed the performance. But after it got going, there wasn't much that could touch it.
100mph in low gear or reverse with a 2 speed power glide
What a sweet sounding little Chevy.
Hey Nick , me and the Chevy Impala a 1966 to be exact have a Love - Hate Relationship....back when I was growing up ,in 1969 . I came out of my neighbor's driveway on my Firestone GTO bicycle, not looking and got hit by a red 1966 hardtop Impala with a Mom and her kids right after school , she was running about 35 mph .. Luckily I hit on the right side of the front highlights & hood . Well....me and the old GTO Bike went over the hood ,came down the passenger side ...I took the passenger mirror off with my back , when I hit the mirror ,it shot me and my bike about 25 feet into the driveway I came out of ...talk about rocket man ...The mom slam on brakes, stopped ,got out all upset ..Again my Guardian Angel was working overtime .. I came out with a bad bruised back , skinned up knees, hands ,and legs. No broken bones ,or any other injuries...So ever since then I have a high Respect for 1966 Impala's ...It's a true story .. my ol GTO bicycle was no worse the wear ...later in 1978, I got a 1970 Red GTO with black interior, tac on the hood and RAM AIR 400 ....Those were the days ..10 feet tall and bullet proof .. lolololol...love your channel Nick and George...God Bless .
Wow, Sarge.. You know how to take a hit!
@@NicksGarage Yeah ,fortunately.....like the Timex watch ...keep ticking as long as we can .lolololol
Needs more crankcase venting, @20:30 it pushes the filler cap/vent off the filler tube, back when I was racing a 327 in a stock car I had 4 vents, 2 tubes in each valve cover topped with breather/filler caps for a big Chrysler, no such thing as too much ventilation.
I like the ram horn factory exhaust manifolds. I had a 327 from a 69 impala with 2 barrel carb, turbo 350 trans. put it in my 60 chevy station wagon. worked very nicely for family car/boat puller. peanut carter was president and 55mph speed limit. my car would do 20mpg at 55mph and I was happy with that.
We bought a Cordoba in 1975. 440 was still available. 318 was a no cost or credit. I tryed to get mom to go for the 400 4bbl w duals. No Cats on Chrysler in '75 like GM. Mopar got them in '76
400 4bbl would have been a good choice!
What I don't understand is this amazing channel isn't new and I just found it keep up the awesome work!
Thank you.
1st engine I built. My Dad showed my how to and of course helped a lot and I was 16 or 17. What a great engine. Great video!
Very cool!
One thing to note to the owner: find a set of plug heat shields to use with the manifolds. Those log manifolds will cook the plug boots without them---I know from experience. Vette rams horns with angle dumps might fit and give better performance. They have 2.5 inch outlets. Those old Impalas used rams horns so they should fit OK. Older blocks had the road draft tube at the back of the block next to the distributor. California emissions had PVC valve mounted in that hole instead of the road draft tube. "Later" (relative term) blocks lost the hole in the rear and needed the hole on the valve cover. Frequently people would put a freeze plug in the road draft hole on early blocks and use vented valve covers. Oil fill and breather intake stayed on the front of the intake until 1969 when the inlet went to the opposite valve cover. That made sure that the vapors were pulled from one side of the engine to the other.
I have 8mm wires and no shields on my vette and never had that problem you mentioned about melting the plug boots????????
wow thank you.Great info.
Great video for a Chevy guy. Small block on the dyno. Classic. Nice car George and a great video George!
Thanks 👍. Big block on the street coming tonight!
@@NicksGarage i am heading home to watch. Get it fired up!
A friend of mine had a early 4 speed Nova with the carbureted L76 327 365 hp.The car surprised me ,in that the the engine felt much bigger than it was.If he had told me it was a 396 375 hp I would have believed him.
That's a solid lifter cam, perfect for this motor
Your friend may have had the available L79 350 HP 327" hydraulic lifters engine that ran about as well as the L76... get it up to 2500 RPMs and it 'came on the cam' and exploding into HP !!!
The little 3 valve 280" V8 in 2006 & up Mustangs also is surprising and feels like a big block engine!
@BuzzLOLOL The L79 was identical to the L76 minus the flat tappet camshaft in the L76.
Would love to see a 70’ white Cuda next to 70’ white Kowalski. 💪🏻
Impressive little Chevy, Beautiful Impala
Chevy did make a cast iron performance exhaust manifold for the 327 it as called ram horn exhaust manifold and the manifold’s you have on the 327 now are the smog pump type from the 70s had them on a Camaro and a Monte Carlo !!!
Congrats on 200k nick
I had a 70 Camaro I bought new and in less than a week the valve covers were leaking.
I changed the valve cover screws and they were no more than finger tight. I tighten them up but only slowed it down. My experience is when corke gaskets start leaking there is no stopping it .
I replaced them with neosporin gaskets and worked perfectly.
I remember my uncle, who lived in Longueuil, had a 1966 Impala SS 396 convertible, dark red with a white interior (new). That thing was fast for it's time. There was also one in Laprairie, exactly the same, but with a 327. It was a beautiful car and it rode as well as it looked, especially with the top down. Best Regards - Mike
Thanks for sharing, Mike.
