i know for gasser's 4.56s are perfect for 35's. ive got an '86 6.2 with 700r4 3.08's and 35's. after driving at higher speeds, that ratio sucks. instead of regearing my 10b's, im going to swap in 3/4ton stuff since this is going tobe a work horse (i dont have a trailer, its gona be for loads to dump, mulch, collecting car parts, you know the drill). im thinking 3.73s or 4.10s right? those are stock ratios so i could snatch a set up pretty cheap. what do you think? i dont really plan to go bigger than the current 35's.
