I agree with what everyone else said. I don't believe the alum radiator and alum srive shaft are legal in NHRA and the roller rockers (unless factory) aren't either. There have been several arguments on this forum regarding that.

as far as pistons, I would figure most IHRA racers probably have what is in the NHRA guide. I would be suprised if that many don't.

NHRA no longer separates fuel injected cars out either. They run with the original classes.

What kind of car do you have?
