C4 kit car
As for books that list all the changes, ive heard that the Black Book does that. Though, it also might just be a production numbers book. Im sure someone in the know will chime in and say.
I donno anything about mags, so good luck with that too.
I believe up to 88 they had what's called a 3+4 transmission which I hear sucks butt. Is there anything about these C4 cars I need to watch for? I'm thinking of trying to get an early 90's one. But the problem is that I like the front and rear bumper from the 84-89 cars instead of the flat rear the 90-96 has. If I got a 90-96 C4. Could I just swap and put on the front and rear bumpers from an 84-89 C4? Or is there more to it?
I just hate that flat butt the 90-96 have. :mad
Sounds like you need to make some serious decisions. You've gone from a bad idea, to a worse idea... There's nothing wrong with the drivetrain in 89's, so if your happy with the body style, go for it...
And, if you want the BEST deal out there, look in the C4 for sale area here... These guys maintain their cars better then anyone out there, and they aren't trying to rip fellow forum members off!!!!
Have fun my friend.
Engines:
L83 - Crossfire - 1984 only
L98 - TPI 1985-1991
LT1 - 1992 - 1996
LT4 - 1996
LT5 - 1990 - 1995 (ZR1 only)
The suspension was entirely reengineered for 1988. Brakes, settings... you name it. Nothing is interchangable.
Dash changed in 1990 (first year airbag)
Body changed in 1991.
Wheels changed just about every year.

If you want a C4 (whatevery body style you prefer) buy one in running condition. It's the only financially-sound way to get one.
If you MUST build your own kit car, get a proven kit like the FactoryFiveRacing Cobra replica.
Doubt if you'll have the money for both for about thirty years, but you can always dream (that's how most of us got our Corvettes; dreaming)

When choosing a year you have 5 basic engines to choose from
84 crossfire
They only used this engne for two years 82-84. That's because there was a better way to build an engine.
85-91 L98 a.k.a. Tuned port
In stock form this engine is 240-250 hp with great low end torque. It's built on a gen 1 small block so there a much bigger aftermarket. More parts to chose from, more possibilities, cheaper. If you're looking for hp/$ this is probebly the way to go. Early L98's used mass-airflow fuel injection. This will adapt better to most engine modifications, the exceptions being an engine that consumes more then 255 grams/second of air or a cam thats big enough to make air flow backwards through the sensor. For radical, high power'ed L98's you'll need a speed-density system and you'll need to get it reprogrammed when you get your engine built. If you want to do a big block it is possible but when you can get a 454 ci small block I'd have to wonder what the point is.
92-96 LT1 or LT4
LT1 came in cars with auto's, LT4's came in cars with sticks, generally. LT1=300hp, LT4=330hp I don't know precicly what the differences were. This engine is more powerful then the L98's but the torque band is at a higher RPM so it doesn't give the same punch off the line. If you watch an L98 and LT1 drag racing the L98 will jump out ahead at first but the LT1 will catch up and pass it by before the 1/8 mile mark. LT1/4 may be more expensive to modify, but maybe not, depending on what you want.
90-94?95 LT5
375hp ZR1 engine. You can't afford this and neither can I.
As far as transmissions go Auto's are generally better for drag racing, manuals are better for autocross or street racing. If you plan on a lot of power be aware the auto's have a lighter duty rear end that may need upgrading.
Major improvements to consider
ABS started in 86 (might want to check that, I think it's right)
traction control started in 92 and improves almost every year
Watch for option codes
Z51 or Z07 Stiffer suspensions.
FX3 Adjustable shocks (If the servos still work)
ZR1 Only way you'll be able to afford this is to find someone who doesn't know their vette is special (not likely)
B2K Same as above but even less likely.
Hope you find this helpful. Do you're self a favor, go to barns&noble and read every book they have on corvettes and small block chevys, then go to books-a-million and do the same thing. Then take a week to think about it all, come up with questions and ask them here. No use buying something only to find out one of the features you need came out a year after your model.
Oh yea, welcome abord. :cheers:

I think it may have had better breaks too. Not sure on that one though.
