Hey guys I'm new to the forum!
I'm planning on redoing my rear diff next week and need some advice.
Stats on car:
67 GTO 400cui bore over .30, forged steel pistons, mild cam, headers, street avenger 670 carb, edel performer intake mani, TH 400 trans with 2,400rpm stall and mild shift kit.
So my question is do you think 3.73 gearing is a bit overkill? I try to avoid highway driving as much as possible (rock chips, etc) but I do drive a couple 30-40mile trips to car shows and what not. How bad is 3.73 on the highway compared to say 3.55?
Any advice would be greatly appreciated!
