Bob,
Through all the 60 years I've been racing I have always heard the Corvette ratings were higher on like combinations because of the Stock Exhaust manifolds and the Stock Pan configuration. For the life of me I can't see how a Exhaust Manifold difference in all classes that allow aftermarket headers is even a consideration for HP variations. Now a Stocker with a Stocker pan.. I can see that there could be a difference...In Super Stock and Super Stock GT where aftermarket pans are allowed I don't see any reason to add HP to "like" engine combinations. Is NHRA Tech going back to some wheelbase considerations like in the old days with Ford and Mopar??
