P.S. If IHRA came west I would be intrested in racing in their program.

I hope somebody can answer your question,but sorry I can't help you.One question that I do have about crate motors is that it has been brought up earlier in this thread that the H/CM class is a 9.5 horsepower to weight class.D/SA is also a 9.5 horsepower to weight class.I was just wondering why the index is 12.00 in H/CM and 11.85 in D/SA?How are the factors of these crate motor engines determined and why the difference in the index?
