Contact NHRA. They can tell you which engine combinations can be used in your car for specific stock and/or super stock classes. Engine blueprint specs can also be sourced from them.

Got to NHRA.com and you can view all the classification guides. I/S is 12.00 to 12.49 #/hp.

http://www.nhra.com/competition/classification.aspx - click on the 1971 Chevrolet and download the word file. This will tell you the #/hp rating if the various combinations.
