FWIW, during the Rocky Mountain Nationals in Edmonton, Tech was using the NHRA guide. if you asked a question regarding a combination HP factor, those sheets came up, with no reference to NHRA. This, even though certain combinations can be found on the IHRA web site with lower HP factors than NHRA. IE 94-97 LT1, 74-76 Chev 400, and the 1965 327-250. Not sure if it was for this race only . or if they are standardizing between the 2 HRA's
