John's 1976 C3 Corvette Gets a Brand New Crate Engine
Вставка
- Опубліковано 24 вер 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 UA-cam feed but subscribed, love vettes an Camaros
A 35 minute Corvette Ben video? Is it Christmas?
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!
One of the best videos I've ever seen. Well edited and explained 100%. Thank you very much
You did great! Proud of you.
Very cool. I have an ‘82 C3 and these cars really turn heads.
I really appreciate your calm and thorough narratives. Kudos!
Great video Ben.....you never fail to be interesting in all your videos as well as very informative. Thanks buddy!!
Thanks for the video. Always like seeing your work.
Man I love this guy. Glad I found this channel.
One of your best videos!
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.
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.
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!
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.
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.
GREAT video! Im about to start an engine swap on a stock 81 and this helped me tons.
Thanks for the great video
I just bought a 76' Stingray, trying to keep it right,
LOVE this video
*Ben, finally!!!!! Great job on yet another decent UA-cam video*
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
LUV your long videos. keep them coming.
Great job. Every car has a story. This is just another one to add to the pile.
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.
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.
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!
That your wife cares enough to know about your tools is awesome.
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👍
Your vids are interesting tbh and it’s educational for me for when I get to buy one of those C3
Great video. Keep them coming.
Great project brother, wish you the best.
Great result Ben
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 job
The gas gauge.....we can fix that later.. haha! Great video, nice work!
Good work sir.
Cool to see someone show what really happened when you put in a new motor
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.
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 $$$
The Corvette c3 - pure art on four wheels!
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..🙏🙏🙏
Excellent job!!
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.
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...
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.
Beautiful car
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.
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...
Excellent video!
I really liked the video! Great job!!
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
Honestly this video made me chub. I love these classic vettes.
That's a very good thing put all new engines in old 1960s cars
Super cool video
Great video.
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
Great video
First time I've seen someone break in a roller cam.
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.
Nice video keep up the good work
dang good lookin car!
Good job 👏 👍
Very nice video. Although back in the day, we would have added a couple cans of STP and called 'er good!
great video.
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!
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!
you forgot headers!! thanks for making this video..
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.
Wow, that Vette shook the ground loose at the 3:35 mark. Break neck acceleration at it's finest. Smoking like a BBQ.
Man, I love the sound of a small block Chevrolet.
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 “
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.
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.
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!
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.
The corvette owners that have local proximity to Ben are fucking lucky!!
Yup I’m with some of these other guys, nice LS 3 would be sweet
you should have done that same test under load again to show no smoke with new engine
great vid
i would go through the old motor myself and use it in a project car!
Ready for a refresh. Valve seals too.
I installed a 350 HO crate engine when my original blew on the freeway (1976 Camaro).
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.
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....
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.
…………...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
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.
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.
It's cool that it still has the Monza steering wheel 1976 only.
With the motor dyno tested, wouldn’t the cam have already been “ run
-in”?? Never had good experiences with Holly carbs either so far, always good luck with Edelbrock.
I wanted to see it go!!!!!
Great video. How does it feel compared to a C3 with the stock L48 engine? Also, do you know what the compression test readings should be for a 1978 C3 L48? mine are from 85 - 90. I believe this is too low.... Your thoughts? I think I'm gonna get this same crate engine... Thanks!
Perfect Vette for the new ZZ632 engine.
few things are glorious as unboxing, or unwrapping, a new crate engine....gawww....dream cheese!
Hey Ben great vids. I have a 76 c3 with a standard transmission that I am putting new crate motor in. Do I need to pull engine and trans together I don't have a lift it would be nice if I could just pull the engine by itself
Good video. with 250 criticisms.
