hey everyone i just found this forum and i have recently came to own a real nice 1976 Corvette Stingray mint condition with 500 miles on it and a 5000 dollar paintjob from my father and well its got a new 350 engine bored 66 thousands over and i wanna make it faster, i know that u really shoulded tubro corvettes thats its not something thats really for a corvette but i want to put a 454ci engine in it and supercharge it but i also wanna supercharge this 350 in it, please let me know what u think and what i should do. ty

 

350 or 454?? you need to sit down and make a plan of what
you really want to do. This gets real expensive.

and WELCOME

 

Tell Monty that turbochargers arn't for Corvettes.

well i wanna go with the 350 for awhile ( a couple of years) because its a strict summer car only and i was wondering if it would be worth supercharging while i still had the 350 in

 

If you have to ask you probably can't do it. It is very expensive and you need to have the ability to tinker with it yourself. To get someone else to install one is just too pricy.
It cost me $9500 to go with my 871 setup.
It ain't cheap

It seems to be every kids dream to drive a supercharged car. A good setup will cost you more then the car. First I feel you have to have above average mechanical skills, it is not something you bolt on a forget, a mechanic can not really do it for you, I know I will get slack over some of this but most mechanics are parts replacers, most don't really understand how things work. I constantly get asked by mechanics stupid questions that any novice would ask.
To set up a motor and turbo takes easily $10000, easily.
I have $20,000 in mine.
Just enjoy the car and drive it like it is. When you are older, wiser and richer then decide if you really want a supercharger.

 

This is my bigblock blower motor

 

Hi Norval, I will be installing a 350 with a B&M 144 that I picked up in Ohio just before christmas. I picked up the low time motor for a great deal.

 

Supercharge the 350 you may decide you don't need a big block.

 

It really depends on what kind of supercharger you are wanting to install. The B&M small blowers for the 350 are pretty simple and give a pretty good torque increase, it will make the small block feel like a big block. If you decide you want to go with a 6-71 or bigger, I will agree with Norval, it can get expensive and frustrating pretty quick unless you have someone that understands these blowers and street engines pretty well. To run a bigger blower you will normally need to lower your compression ratio and beef up the lower end. I'm a crew cheif on a nostalgia funny car and we run an 8-71 on a Hemi with 80% nitro, it's a whole different ball game.

 

Like your new valve covers,looking good.

 

I think you should first decide "small block" or "big block" then go full bore from there. Either way you can get great power from almost any engine. Once you do all the work and go through the expense, you probably won't want to change to another engine because it will be too much effort (just my opinion).

Good luck -

 

Having driven my dad's supercharged Avanti with a Studebaker 289 (punched to 299 cubic inches) V-8, and my naturally aspirated Corvette (when it was a 350). I'll tell you this, supercharge your 350 and you'll be happy.

Now my dad's Avanti isn't your average supercharged vehicle. Back in its hey-day, it ran 12 psi of boost on 9.6:1 compression. Vince Granatelli and his brothers got their hands on it. My dad's car was the 25th Avanti built and was a factory R2 engine. Vince did some reworking with Paxton Products in Santa Monica, CA and it became the prototype for the R3 engines (9 produced total). My uncle calls the work on the heads, "amazing." That supercharged 299 beat Hemi equipped Mopars in the half mile; a quarter mile wasn't long enough to get its legs stretched out.

When Studebaker set 29 U.S.A.C. records, my dad's Avanti was one of the cars that went out to Bonneville. I think it did some flying mile runs.

My long term goal for my Corvette is an LS_ (1, 2, 6, or 7) punched out to 427 cubic inches [already done for me on the LS7], breathing through a Whipple (or any of the twin-screw designed) supercharger.

 

I would recommend you pick up the book, "Street Supercharging," by SA Design books. Gives great advice for the novice, helps you to understand what supercharging really does... AND, how to know if your engine can run a supercharger without changing pistons....

But the bottom line is, if your 350 can run a mini-blower, then the engine will think it's a big-block, and give big-block power and torque numbers....



Do some studying, get yourself prepared.... And when you're ready, jump in! I did, and so far I'm quite pleased with the results... Also, be prepared to do most- if not ALL- of the work yourself (another reason to research this carefully, before making the plunge). I'm with Norval, on the supposed "expertise" of most mechanics- you'd not BELIEVE some of the stupid things they say... Most of 'em, if it's not in their reference manual (which of course, a highly modified and supercharged BBC never is), they're clueless... So, forget about the certified mechanics being able to help you... Even most "hot-rodders" will be clueless, when it comes to practical knowledge and setup experience on blown motors...

BTW, I would not recommend doing a supercharged BBC in a Vette, unless you have lots of money, and lots of time, to get it all worked out.... I've been working on my blown 427 BBC for two years now.... and HOPEFULLY, it'll be on the road by spring... It's NOT easy.

 

lol, that u everyone for ur ideas and stuff, but im not a complete idiot when it comes to this stuff, i am a mechanic, my dad owns his own mechanic shop and ive turbo and supercharged cars before, but this is my first corvette so i decided to ask people who knew what engine whould work better in the corvette, i just wanted to know if i supercharged the 350 that it would be better then the 454 would or if the corvette would run better with a 454 supercharged, as for the money im not worried about because i have well over a couple of million to spend on this car if i wanted 2, i was also looking for info on what superchargers the corvette would run best with with both the 350 and the 454 engine and maybe info on the 427 cause i could also consider that a option, ty so far guys

 

nice blower btw ^^^^^^^^

nice motor what cubic inche is it and do u know what kinda horse it puts out @ the tires?

 

you're going to be very popular around here

good luck on your project

Jim

 

One goes away another takes his place, please help us

 

Sounds like you got a sweet deal with that car just the way it is....I'd just drive it and enjoy it the way it is...what can I say...I'm a purist..

 

 

build both and see which one you like better
