with a 235 75 R15 tire, 3.25 gear ratio, your engine will turn 2459 rpm at 65 mph. 2837 rpm at 75 mph
3.08 gear will be 2330 rpm at 65 mph, and 2688 rpm at 75 mph.
I should mention these aren't totally accurate. But I would assume they're close, as my calculator factors in a 302 cid....still a V8

That sounds just about right as far as what I'm running. 25 - 2600 rpm at 70 mph.
My B/B has enough torque to pull 3-0s, any lower and it would be really revving on the freeway. I haven't tried to really light em up from a standstill yet. Stop light to stoplight could probably use 3-25s for a better holeshot. It all depends on what you want.

2 thirds of the way down talks about the Ford Explorer rear end. It's a fairly simple swap.

Thanks, Guys. The Explorer rear end is more trouble than it's worth. Sticking with the F100 direct swap. The guy who sells these will put in whatever gear ratio I want. I'd like to drive this truck fairly normally, so I'm looking for a good all around ratio. If I drive to Reno Hot August nights, I'd like a smooth highway drive!
