Stock L-82 still in it now should I leave it or maybe go with a EX268H ?? any other advise.
you didnt say if ur 700r4 is stock, shift kit or what stage? even with, i agree ur gonna need more gear to get off the line, i'd go with something around 3.33 to 3.43, 280/290 cam sounds alittle to big to me i think ur 268 is about right, but i'm doubting ur 10.2.1 comp unless you did something to the motor like pistons and heads, for a correct answer you need to give more info on ur motor and tranny, but with a 3.43 gear with the overdrive should be fine on the hyway, butch
