that be a good combo .

lots and lots of nv4500 swaps out there done .

nv4500 swap with 33.0 tire @ 75mph

3.08 = 2350 4th / 1760 5th o/d
3.42 = 2610 4th / 1960 5th o/d
3.73 = 2850 4th / 2130 5th o/d
4.10 = 3130 4th / 2350 5th o/d

here ya go play more if you want . every box can be changed for speed / feet / mph distance . huge drop down window for trans options . http://www.grimmjeeper.com/gears.html
