I’m fairly certain that if a car has an NHRA class that you have to run it instead of the IHRA class. I didn’t see a clarification listed in the S3 rules but I think Gene has posted it on here before.

I’ve only ran a couple of NMCA races and have ran B/SA each time instead of B/FIA, also with an LT1. IHRA HP rating is more favorable in most cases.
