Tom, that explains it, this theory might not work with my KC Nascar based engine being a bit bigger in the ports and camshaft, I dont envisage it will have much below 4000rpm, however I have been told KC does a good job of producing engines that pull quite well from 2500rpm up. Is there a tendency to have it coming in higher up on less streetable engines, as a 427 which I have owned pull better down low?
