Shipping weight is 3122. get that from NHRA stock car class guide. 14.19 factor, 220 hp

3122/295= 10.58 natural J/CM
10.5 x 295 +170= 3268# race weight

I/CM 3120# race weight

in IHRA Crate motor, no diff bwtween stick and auto. run off same weight break and index.

Need to clarify the shipping weight through IHRA though. NHRA lists one weight for automatic car, a lighter weight for stick car if you were building a reg stocker.
I used the heaviest weight.
