Lynn,
I have good understanding of the class, I'm amazed by the performance levels that are achieved. I know it's all based on the engine factors by NHRA. So the question is, who is making the most HP with a D-port and a R-port and how much is it? Has anyone had any luck with the 1970 455 HO or is the factor just too high in comparision to the high compression 428?
