1971ls6: I believe you're referring to the "Pure Stock Musclecar Drags" series in which you must run manifolds and bias tires.

Mark: IHRA has a Pure Stock class that NHRA doesn't. Our local series runs under IHRA rules which open things up to more participation from 'different' classes. You can't use a 'stocker cam' as a traditional stocker can. But I've read here that you should have a cam ground which will check within the specs but should work better than a dead stock grind.

Can run headers with mufflers OR open manifolds.

You can check out the rule book at http://www.ihra.com/.

Thanks for the replies guys.
