4BT. NV4500. 1750 rpm, 35" MTR's, 65mph, = 3.73 gears

Right??? all sound good there??? I've tried several calculators and this is what I'm getting.

second the rpm, my spreadsheet came up with 1752, but whose's spliting hairs.

and that's where I want to be on the hwy for mpg, right?

that should be pretty good, rpm-wise.

One thing, actual tire height will make a difference, and if they are MTR's, it will make a pretty significant difference, they run small.

3.54's with 285/75 r16's was right on the money. measures out right at 33"

so yes 3.73's with 35's is a good combo. i have that in my dodge now and i tow alot and the combo is almost perfect for when loaded and when emptymileage and power balance
