Probably been a subject discussed bunches but I will be working on my Banjo rear for my 39 ford pickup with 3 speed top loader , and am wondering if anyone on here has ran a 325 or 3.54gear , and how it worked out. I have yet to determine my current gear but 38 ford pickup had 3.78 or optional 4.11 , not sure about 39 though. Have looked for the gear ratio stamping but just cant see it. Will really search later today. i just want a little more highway speed, not intending to run on interstate .
