I have a 87 notch with a iron 370 swapped into it. I'm awaiting a front mount 76mm kit. I'm curious what gear I should be running in it? I am running a 275/40/17 tire on the rear an a t56 transmission. It currently has 3.31 gears in it. The gears are way to tall for the current cam only ls1, but I'm not sure how it will be with the boosted setup. I'm shooting for a 650whp daily driver that will rarely see track time because no cage.
Thanks
Thanks

i use 6krpm as a reference because thats where i shift with a stock bottom end. with your motor being forged, youll obviously spin higher which means youll get more mph out of each gear. With 650whp in a foxbody, youll be over 140mph in the 1/4 mi and you dont want to be shifting into 5th gear. 3.31s are perfect.

Although the current 3.31 would still work well, especially as the vehicle is quite light
