I dont suppose youl be hauling fire wood, cinderblocks or old cars with it.
you will be greatfull for the better milage and the current(?) or future use of an overdrive with a 342 gear set up. Your 308 differential "case" is compatible with any gear ratio bellow 373, so to choose a 342 ring and pinion will save a bit of money there, but 373 diff cases are quite common too and ought not to cost much either.
tough call . I like my 373 gears but sure wish It was more hiway friendly that 95% of the time.

Well this truck is gonna be a fast show truck. I was worried about the 373 with the th350 not having an overdrive gear. Idk if 3.08 is gonna be fun enough though. I'm considering 3.42 now then.
