Having some experience in asphalt banked oval stock car racing, and watching the Compact Class at our local speedway, I want to add one to our racing team's lineup. Having given it some thought as to just what car to use to compete with the Pintos and Mustangs and Celicas, I want to use the "Baby Vette"!
Of all you GT lovers and experts out there, who can give me advice as to whether or not this might be a good idea?
Can a GT be (slightly) modified to kick Ford butt?
The rules for this class require relatively stock engine but of course must be built bulletproof at high RPM. It appears (with a GT) there isn't much choice for differential ratios, but there will be some options available by running it in 2nd gear, will take experimentation between ratio of 4-spd and 5-spd.
Naturally, handling is the key. I am told the GT turns sweet. Is there a lot of camber adjustment available, like the 6 degrees max allowed in this class? Upper and lower A arms may be modified, according to the rule book. "Any bushing material may be used" unquote, I see there are some options here for the GT.
Carburetor limited to 390 CFM, max.1-1/2" venturi diameter...any thoughts here?
Will spare body parts (not necessarily in great condition) be available for the GT?
I really hope you GT enthusiasts will give my idea a thumbs up and offer lots of advice and possibly even some help.
Thanks a lot!;)

3.44 3.67 3.89 4.75 5.00 5.15 and 5.28 are all available from Risee in Germany. Bring your wallet!

No adjustment in stock form. Youll need to modify the stock unit to be adjustable or build some from scratch

You'd be better off building a Manta for short-track racing. The GT's handling is not that great in stock form, especially with rules limitations. Also a GT has ALL welded-on body panels with the exception of the doors, hood and headlights. And we all know how short-track cars like to swap paint!

I've had a lot of experience with the Manta chassis on a 1/4 mile asphalt circuit, it has always been the best handling car out there in a sea of Mustangs and Pintos. Needs a lot of work to make it run with the 2300 Fords in the power department. You're giving up 400 cc's, which is a lot. If you can sneak a 2.2 Opel engine into it, then you'll probably dominate the class. We had a 2100 cc engine that could outrun 2.5 litre Super Duty Pontiacs, but we had to rev it hard.
