I do not think that IHRA would have a problem with the grill or louvers.
Even NHRA allows non Z-28 Camaros to use Z-28 trim.
Aluminum drive shaft is allowed in IHRA stock.
Pullies should be OK.
Cold air kit needs to be looked at by IHRA tech as some direct replacement units are OK.

Good luck.

thats good news. My control arms are both non-adjustable.

Do you think I fit more in with Stock Fuel injected or Modified stock, im trying to see who i can contact at IHRA for more info. What division is FL in IHRA?

so they add 170 pounds to the car's weight no matter what?

I only weigh 160.

Tweaker - You need a crash course in class racing. Classes are determined by horsepower to weight ratios. Each engine has a horsepower rating assigned by NHRA or IHRA. Each car would get a hp/weight factor depending on the listed shipping weight of each vehicle. This is what determines your class. (170 lbs driver weight is added to shipping weight to determine minimum racing weight. It doesn't matter how much you weigh.) You are then allowed to do certain modifications depending on your category. Stock can do so much, Super Stock even more. You then must be able to run on or below the ET index for your class. The problem is that you would probably not be able to run your index without building your car to the limit of the rules. (acceptable cam and valvetrain, blueprinting, gear ratio etc.). If they run a bracket program with the IHRA race, you'd be far better off there.

im assuming id get killed in super stock, can't you use electronics in that class? i dont have any :P

[Mike Carr]

Super Stock allows transbrakes and air/electric shifters. No delay boxes or throttle stops. Check your Private Messages, I sent you some info that should help a lot.

Dont be discouraged i went through all of this a couple of years ago, once you take your bumps and bruises it is an absolute riot. Get a rule book and find some class racers and ask a LOT of questions
