every thing , tires, motor, carb, heads, exhaust, trans, wt. driver, the way you adj. you valves makes a dif. i dont think there is a rule of thumb on that. the starting point is to figure how many rpm's you wonted to turn in the 1/4 mile and and get the tire size and gear ratio so when you go through the lights at the end of the 1/4 youll be turning the rpm you fell like you should to be getting max. power out of you motor.. if you think you set up works best at 5500 rpm then thats what you wont to turn when you go through the trap. use your cam as a start.
