488's
pinion is a little larger so it will be stronger for the hp and big tires your running

go 4:10 if power is no issue,less chance of breakage

nope you are all wrong with a motor that needs that high of rpm to produce power you will want as low gears as you can get. that motor is a rever not a 4x4 motor and to make up for useing a drag motor you will need low low gears.

I guess for mud that would be fine but would really suck on trails especially with a 3000 stall.
