I have several iron heads that are NHRA Stock Eliminator legal. Looking at the flow #'s, all fall off around .500 (+_/-) .15. Using these heads in a bracket motor, can I get the best bag for the buck by using a roller cam and taking advantage of the faster ramp speeds? The FT stocker cams are very steep and very detrimental to the lifter, cam and valve train. I also won't need to keep the factory valve spring specs. I just want to be able to maintain or exceed my present ET/MPH. A cheap, dependable bracket car.
