As I continue to learn and realize how little I know I have come up with a few questions. 1) When someone says something like "I have a 260 cam", where do they get the 260 from? ie. Which number in the cam specs does that represent? 2) It seems that smaller intake runners on a head produce more TQ and larger produce more HP. Is this correct? 3) What does "CNC" mean? 4) Will a TBI unit produce as much power as a carb. of approximately the same size? Say a 730 CFM TBI vs. a 750 CFM carb.??? I'm sure there will be more to come. Thanks for the help.
