John's 1976 C3 Corvette Gets a Brand New Crate Engine
ฝัง
- เผยแพร่เมื่อ 24 ก.ย. 2018
- The old motor in John's Corvette started smoking and using a ton of oil. Since the heart needed replaced, John opted for a Blue Print crate engine from Summit Racing. See how it goes from pulling the old one, to starting up the new!

What’s crazy is someone out there was super proud that they saved that original fan shroud at one point in time
Hi Ben, I like what you did here. You repaired a customers vette to his specifications, expectations and cost budget. You took a car with a worn out engine that might have been making all of 90 hp and put in a motor putting out 380+ on the dyno, so probably now 330 to 340 at the rear wheels. All for a price your customer could pay. This is a big win. The fun factor increase for this car just went up like a SpaceX Falcon rocket. This corvette is a driver, not a restoration. I have no doubt you had a detailed set of conversations with the customer about what his options were and guided him on making the best choices for him. By delivering a well executed budget end product, I bet you have acquired future work and income from this customer and possibly some of his friends. There is a difference between repairing customer cars and your own cars. Your time has economic value. So does the customers available funding. And another corvette stays on the road. Good job.
I appreciate the kind words. You have no idea how much.
Great comment. I totally agree. All this "numbers matching" stuff has gotten way out of hand.
@@TheCorvetteBen doing a grt job Ben,
Not his car, not his money, not his choices. Thanks for showing us the process, appreciate it a lot
Alot of people don’t like the paint but i love it
A lot. Alot isn't a word.
Idk how your channel has never popped up on my TH-cam feed but subscribed, love vettes an Camaros
I gonna keep this video in the watch list for this winter when I drop a 327 in my 78. Can't wait to have a good engine in the car!
For all those saying keep it original, these cars were slow and boring and will never be worth much... but great lines good suspension and can bolt in an awesome engine.
So true, if you're gonna get a Corvette, it should be fast and sporty, and a 76 corvette with its original emissions-regulations plagued engine, is not gonna be fast.
43 year old cars don't need to brake land speed records, tune the carburetor if needed and enjoy the sexy curves that all the C3's offer.If speed is what you're after, break the bank and get a C7 or SRT Demon.
if anything keep the original motor so its still numbers matching.
Exactly, these cars looked beautiful, but were completely screwed over by the 1970s government regulation issues. There are a prime vehicle for an engine swap to make them what they should have been and better.
I pulled the L-48 boat anchor out of mine as well...I'm sorry its a vette its supposed to be fast...Pretty Embarrasing when you have a soccer mom pull away from you with her SUV filled w kids...
If you want a slow car buy a 4 door sedan...
A 35 minute Corvette Ben video? Is it Christmas?
I really appreciate your calm and thorough narratives. Kudos!
Thanks for the video. Always like seeing your work.
Great video Ben.....you never fail to be interesting in all your videos as well as very informative. Thanks buddy!!
One of the best videos I've ever seen. Well edited and explained 100%. Thank you very much
Very cool. I have an ‘82 C3 and these cars really turn heads.
Good video, I like you’r work ,and manner. I’ve seen the same color on an other C3 corvette
once before. At that time thinking the color was a custom paint job. Nice to see you taking
correct mechanical care of this corvette.
I hope the owner goes through the process of rebuilding the motor. That would be a huge selling point to have the original motor - even if the crate motor is in the car.
That year engine is not that desireable at all. Even though its the original one, it was completely killed by emissions. It only came new with 165 hp.
You did great! Proud of you.
I did basically the same thing to my Brown Met. 76 glad i did she chirps 2nd gear now. Thanks Ben keep it up. Great video!
You work hard, sacrifice a lot of family time to get the job done,do a fantastic job & your tutorials are 2nd to none, no crap music a lot of content, you Sir are a great video presenter & have a lot of patience...this corvette get's to live & i like the car as stock, not bubberised up ...keep it up Ben..if i lived in your area i'd get a corvette so you could work on it & get it back to stock...love the corvettes.
Man I love this guy. Glad I found this channel.
Great "How To Video" Thanks for taking the time to make and share this video. Very well done.
I got many chuckles from the arm chair critic's comments.
I purchased my one owner 79 L-82 last year for the love of its classy looks and to also remove a Corvette purchase from my "Bucket List". It's a warm sunny day cruiser from May until November. I spend my long Canadian winters doing my priority things on her. Complete renewal of rear suspension, U-joints, spindles and bearings, differential stub shafts and so on last winter.
This winter's projects I'm working on are a complete rebuild of the front suspension and steering. A new aluminum rad and electric fans. Replacing the 2-1/4" pipes with 2-1/2" back from the ceramic coated headers and working over my transmission crossmember to let the pipes run straight back until after the crossmember to make room for the 2004r transmission I have on the bench that will be rebuilt strong enough for a future engine up grade of fresh Vortec heads (on the bench) and Edelbrock manifold and maybe a different camshaft. My goal for this is for lower rpm's on the highway, fuel savings and respectable power. It will never be a ground pounding drag car nor a numbers matching Vette but rather a reliable money hungry Classic which will always present herself well. It will be passed on to my son. All original parts will be kept if anyone wants to have a #s matching car. lol.
Well, I'm a purist, enjoyed the video, would've enjoyed more if old motor was sent out for rebuilding, internals, had the heads worked, original carb, and most importantly A/C, cause now it's just a 76 non matching #s Vette, I'm sure anyone over 50 feels like me, at least store the old motor, carb, and pollution stuff, so possibly the next owner has options, I'm not even a Chevy man, but a Vette deserves some respect
And it is worth no difference with newer or older motor. My 81 is all original with 68,000 miles . And it would probably bring more $$$ with a better motor.
DANNY NOEL I understand that, I'm just an ass like that, maybe a crate 454 would sound better?
Danny, less than $500 in parts and some elbow grease can turn your 68K miles (barely broken in) engine into 375 HP... same HP as this $3500 crate engine... I would suggest headers and true dual 2 1/2 pipes/mufflers so it can breathe out... a little touchup porting on the heads... 2500 RPM stall converter for an L82 cam... similar to slightly better Summit K1105 cam...
A $1,000 in parts to 'rebuild' the worn out engine in the video...
a set of 64cc heads on this motor would have raised the compression enough, and some I beam rods could have kept the engine together. Wish the original engine could have been kept.
1976 Corvettes only made 180 HP, It's better to replace it! And I'm 59!
GREAT video! Im about to start an engine swap on a stock 81 and this helped me tons.
I just bought a 76' Stingray, trying to keep it right,
LOVE this video
One of your best videos!
Oil usage is common on older cars that are not driven much, and the oil is not changed often enough. The oil control rings get stuck in the ring grove because of the waxes in the oil. The thicker the oil, the more wax is in it. Also short trips wreak havoc on engines, plus it could have overheated, taking the temper out of the rings.
I can't stand finding hacked up aftermarket wiring for alarms and other accessories. That is always the first thing I remove, as it always causes other problems. Plus I hate scotch locks and crimp connectors... I solder and shrink wrap everything.
With the alternator, the voltage did look low, but remember voltage will increase as amperage output decreases.
The other carburetors you have, just need a good rebuild. There always rebuildable, unless the casting is cracked or broken.
Great video... Thank You.
Great video, I love vettes. Makes me laugh when you read the negative comments on how this should of been done or this is what I would of done or why would anyone ever do that..This was done between him and the owner, it was the owners final decision. If you would of done if different that's great then do it but what matters is it came out nice and the owner is happy. Again good job👍
Sadly it is the way of the internet. People only criticize even just the little tiny things.
@@TheCorvetteBen So many negative narrow minded people who don't understand it doesn't matter what you would do it only matters what the customer wants..Good his bro👍
I did same thing in 1987 to my 74 vette but it had a 454 in it and for a second I didn’t think the engine lift was going to hold it .. good video
Thanks for the great video
Your vids are interesting tbh and it’s educational for me for when I get to buy one of those C3
LUV your long videos. keep them coming.
Im an old fart and would have rebuilt the matching engine, but great video!
The original engine would need better heads and cam to make that power plus a complete rebuild and it wouldn't have a warranty.
John probably wanted a fresh crate motor and didn't mind tossing the matching one. Not really Ben's decision.
Agreed. I'd have kept the numbers matching engine and had it refreshed. Although it may have cost more than to just pick up a new long block. I dunno though. As long as it weren't a daily driver i'd have spent the additional money I think. I've been struggling with that thought on the motor in my 79 Chevy K10. I'd like to upgrade to a newer L31 Vortec style but part of me doesn't give that much of a crap about the little bit of extra performance because I drive my truck about as often as I go to Houston which is almost never, lol.
Me too.and better..afford headers as well
Im with you on that one. I think its a heavy duty block,crank and rods.
I hate when people do these projects in different videos and you sometimes end up getting them out of order. You tied the whole project into one video just continueing it on separate days. Made it easy to watch and follow the project. Well done and yes I actually always liked that color on a vet.
Hey bud, just subbed, been watching the Caddy vids, got a soft spot in my heart for 49-69 Cads. (I had a 69 SDV and my bud had a 49&52 waaay back-he has a 53Coupe now, I have a 67 Galaxie500 2dr) Anyway, I do enjoy your show, and this Corvette build is no exception. Alright, I wasn't gonna do this, but, he shoulda built the L-82, those are 4 bolt main and steel crank motors! I know, customer's car, customer's decision, just my $.02 Thanks fer takin' us along....more Cadillac! Keep up the great work, also enjoyed the resurrection of the old Merc...
*Ben, finally!!!!! Great job on yet another decent TH-cam video*
Great job. Every car has a story. This is just another one to add to the pile.
My '75 has basically the same set-up, runs great and a lot of fun.
Love to see a follow up video with everything fine tuned like carb exhaust etc. and see how she does fully opened up rpms!
Just came across this video. Nice presentation. I've had 8 C3 Corvettes over the years, from mild to holy shit. 74/75/76/77 Corvettes are pretty much the low point for Corvette resale (other than maybe a 1984, but that is what makes them interesting for a project. I have to say though, that first, this car had the L-82 engine, which actually had decent potential. I bought a bone stock 76, L-82, 4 speed car. Changed to headers with a full dual exhaust, including dual CATS. Re-worked the stock Quadra-jet, added a better HEI, a performer manifold and the car went 14.0 @100 on regular Comp T/A tires. The bottom end on the L-82 is a good piece, including 4 bolt mains, and a steel crank. Heads are not bad. Cam is small. Just for the heck of it, I put on an NOS 100 shot and it went 13.0 @110. Fun car....this was back in 1996. I did ultimately replace the engine, as I didn't trust the rod bolts, and it had developed some excessive crank end play. Put in a Pro-flow injected, aluminum head, roller cam 350 with a Richmond 6 speed. A lot more of everything, but big $$$
Sweet looking engine. Exactly the same power ratings (389hp 412tq) I had from my N54 BMW straight 6 after a little tune. That was a quick car and a fun amount of torque and power. So this should be good for a older vette that you just want to have fun in.
Great project brother, wish you the best.
Looks good I swapped in a blueprint 396 stroker in my c3, sounds great and goes like hell :)
Did you use the original trans and rear gears? I'm thinking about upgrading my 350 with a 450HP Blueprint in my 71 Vette, but I want to make sure the trans and rear can handle it. I would think it would since they had the LS6 in 71 with 390HP?
Great video. Keep them coming.
Super satisfying video to watch.
If I were the owner of that car I would have done two things differently, I would have kept the old engine and I would have upgraded to headers and duel exhaust.
I've looks around a few places on youtube to even get familiar with such an awesome car. My grandpa happened to be put into an early grave, damn cancer. but he has a 77 stingray we were beginning to work on I want to help keep it running good and in shape for my grandma since she's got enough on her mind. Just learning as much as I can. This smoke is a pretty similar problem in his.
Great result Ben
It's funny to see you have the same engine hoist, Jack, Jack stands. Lol Harbor freight has some decent quality tools. I bought a Dannmar lift 2 post fits in my 10' ceilings. Can't lift all the way up but man it saves you a lot of bending and crawling around on a cold dirty garage floor. Great job. Peace
Cool to see someone show what really happened when you put in a new motor
The Corvette c3 - pure art on four wheels!
Great job
I put a crate motor in my 75 Stingray, and tossed the numbers matching original. Reason being? I'm gonna croak in probably another 20 years, so I could give a crap about numbers matching. It's a way better car with the crate motor.
1975? That's a malaise-era C3 Vette. It ain't no collector's car. In fact, the base engine that year was the least-powerful V8 ever put in a Vette. It made 165 wheezing, emissions-choked, low-compression horsepower when it was new. You can bet more than a few of those paltry ponies escaped the stable between then and now. If I had one of those, I'd LS-swap it without a second thought.
Good work sir.
You can double the horsepower on SBC with a Thumpr high energy cam flat top pistons and vortec heads and the air gap dual plane edelbrock manifiold,headers and magnaflow mufflers!
The gas gauge.....we can fix that later.. haha! Great video, nice work!
Got a tonne out of this vid...ready to start on my 73 coupe 350 4spd. I have had it for 30 plus years..ready for a new heart..🙏🙏🙏
That your wife cares enough to know about your tools is awesome.
Beautiful car
That shroud could be a work of art if you mount it on a block of wood & stick it in one of those artsy fartsy galleries..lol
Excellent job!!
Honestly this video made me chub. I love these classic vettes.
I really liked the video! Great job!!
I had a ride in one of these when it was only a few years old, and it was already a disappointment, with valve tick and rattles. I love them regardless, and proper h.p. would be so exciting.
Excellent video!
Very nice video. Although back in the day, we would have added a couple cans of STP and called 'er good!
I enjoyed watching your video, and learned a lot! I would pay you to put new 5.0 in my Mustang if I could afford it lol!
Thanks for this vid. I would not have dropped in a Blueprint engine and bolted it up to the original exhaust, which is probably robbing power from it. Should have gotten some headers, and a dual 2.5" to 3" y pipe, and a 3" cat, and a decent muffler. The exhaust manifolds should have put in a corner of the garage. I like how you showed what was involved in replacing an engine. Might want to look at getting a shiftworks kit and dropping in a built 200r4 now. getting ready to do the same to my 86 firebird Lg4. This gives me a better idea what will be involved now. Got all the valvetrain in my closet.
That's a very good thing put all new engines in old 1960s cars
The corvette owners that have local proximity to Ben are fucking lucky!!
First time I've seen someone break in a roller cam.
Super cool video
In '85 I bought a 72 Chev C10 Step side pick up. Member of the family for nearly 30 years.
Sure, one plug would foul (#3) but never smoked like the C3. Was told get to that point, Rebuild.
Great video.
Nice video keep up the good work
Great video
Yup I’m with some of these other guys, nice LS 3 would be sweet
dang good lookin car!
Wow, that Vette shook the ground loose at the 3:35 mark. Break neck acceleration at it's finest. Smoking like a BBQ.
Good job 👏 👍
Man, I love the sound of a small block Chevrolet.
I just did this to mine. I removed both ft tires, had on Jack stands and put the hoist on the pass side. Not to bad.
That is a beautiful car, surely worth the new engine....Too bad the original one couldn't be rebuilt and beefed up a bit, but I know that would be a major undertaking....And I'm sure this new one will run rings around the old engine even in its best condition...Wonder if John will keep the numbers matching engine, just in case someone down the road wants to return the car to stock form....
great video.
you forgot headers!! thanks for making this video..
in 1976 the corvette had no power 180hp i believe, so i am glad you changed out the motor to one with more power.
sadly some corvettes in this era came with a 305 v8.....140 hp
The l82 was rated at 230 hp I believe, had 9 to compression, steel crank, forged pistons, big valve heads etc.
@@royhinton3046 in 1976 the base eng L 48 was 180hp the optional L 82 was 210hp.
Great job!. Not sure if you know, but you can put the rear of the car up on ramps and the nose will be itched down. The you can lift the engine and transmission as an assembly from the front of the car. it also makes it so easy to put everything back in. I have done so many C3 engine swaps. tell your customer to get the original L-82 rebuilt. Keep the original 9:1 heads with 2.02 intake valves, just rebuild them as original and that motor is worth money to someone in need of one.
Bubba was definitely at home with that fan shroud. So much so that it maybe deserves a new word in the English language. I vote for 'Bubbaneering...'
Yet you have people comment about how arrogant I am on judging this bubba and his fix...
TheCorvetteBen Yes... It's sad really, it's perfectly possible to do a cheap repair on something well. There's nothing wrong with that. But bodging, it's just not a good idea. All it takes is a little thought...
one maybe 2 brackets might be okay in a pinch, but this person took time to do those brackets. True "Bubbaneering"
Ben - like my sainted mother said “ consider the source “
…………...yeah Ben, when you initially started up John's 'vette it DID smoke blue right away ...........so the rings look like they might be done. I missed if you mentioned how many miles it had on it but it appears to have had a good life though. Oh, when you put it in drive and drove it a bit it really let out some blue smoke. Time to buy some oil by the case. :)
Before the engine swap he was buying oil by the case. It was kinda crazy
Perfect Vette for the new ZZ632 engine.
the break in oil is probably just simple diesel oil, that's why it's blue. it has far more additives that conventional oil, and is a lot of old school mechanics swear by it.
I installed a 350 HO crate engine when my original blew on the freeway (1976 Camaro).
Nice car. I had a similar issue with my '72. If you revved to 3,000 or beyond it would smoke like that.
Eventually the motor came apart.
Ready for a refresh. Valve seals too.
if you want to learn this was great ! i had same vette same paint and tools , the problems and solutions were real . like real life situations are tks
had mine 20 years, great car but i too would have tucked the # motar off too the side also - for the next guy to spend his $ on and he did
Hi Ben, Great video. I really like the style of your videos. I feel like i was watching a video of some DIY show on HGTV! LOL It has me thinking I should do the same to my matching numbers small block 73 Corvette. After all, your did it in 35 minutes so I figure I should be able to do it in about an hour. LOL.
Approximately how many hours did that project take to complete not including issues with the carbs?
Also, I would love to see you do a video focusing on how to set the timing correctly. I've watched several videos online but it just hasn't clicked with me yet.
Really a how to guide when buying and older car. The other is to reverse in a tight circle to check rear end.
Look at the bright side... your exhaust system won't rust...
It's cool that it still has the Monza steering wheel 1976 only.
Having owned a 79 with a 60s LT1 engine lightly massaged to around 400 HP I can say this. They are fantastic looking cars IMO and the stock performance IN ALL WAYS do not do the shape any justice. If any car deserves a resto mod it is these cars. These are like the perfect car for an E-rod and THEN whatever is possible within a reasonable amount of spending to make it turn and stop to handle what a current SBC of around 400-460 H.P makes.
My 79 with an old-school 350-400 hp small block and most everything else stock besides some bushings and replacement parts was scary in all other ways besides running it from 0 to whatever the MPH was at the end a 1/4 mile run. My car ran with stock Toyota Supra's , Grand Nationals and My friends Anniversary Turbo Trans Am with the GN-X set up.
A little bit of modernization on these cars that are really 60s tech/chassis/platform and an engine with around 400 HP makes a cool retro car with timeless IMO styling that wont try and kill you if you use it more like you would a modern car.
Any more HP then 400 you would need a lot of $ to make it stop and handle to be reasonable beyond going straight and fast.
They can be had relatively cheap and therefore are a good car to make a street 'hot rod". If you don't like the shape of the C-3 I don't know what to tell you (the 80s cars might be for a certain taste but are lighter then the 70s cars and not without charm but these or my 79 with the more practical bubble back are some of the only 60s "muscle cars" built throughout the 70s and not overpriced and don't have rusted body panels for obvious reasons.
I don't think an E-rod type of engine makes you lose much if any of the feel of a sixties car and you can just put a carb crate motor with bigger secondary's for a more stock feeling.
With the release of the C8 and previous corvettes I think a 400 or so HP set up is fine for that nostalgia feeling because going much higher to compete with modern performance its just easier cheaper and safer to buy a used c-5 c-6 or even C-7 and throw some boost at it if it isn't a boosted model.
you should have done that same test under load again to show no smoke with new engine
great vid
headers and high flow mufflers make a lot of difference on small block chevy performance.
My personal relationship with Holley carbs, after swapping internals, set up for flats or hilly areas, is you can’t win. I bought a Carter AFB and it tried to run from the first key start. After that, I never had to readjust it from the first day.
Threw all the Holley spare parts away. Never will I touch a Holley carb ever.
