im running a 1988 notch mustang with full race suspension ( weights about 2700 lbs) with a 331 stroker motor with Nitrous. the cam im runnin maxes out at 6500 rpm, the rear has not yet be decided either 4:10 or 4:30? i just dont want to run out of rpm's in the quater, i know this all has to do with gearing ? what is your thought on this? if you need anymore info i will be happy, what would the diff in the launch be if i went from the 3.27 to the 2.87,
