Re: IHRA Pure Stock Classification?
If I'm not mistaken the classification follows NHRA's numbers and can be found on their web site. Regarding which class it will fall under then you can look at the IHRA web site to see the rule book. The indexes will also be listed there once you determine the class. The rules are pretty close to traditional Stocker rules except you must either run a full exhaust (or no exhaust but with stock manifolds), cam must remain OEM for lift AND duration, no electric water pump, and a couple other small items.
