    The catalog doesn't mention cube size but I do know how lower displacement will raise the range of the cam. It's like My best guess on the stall was about 700 rpm off. Cam is 219/228 and .550/.550 114

    That cam would need atleast a 3400 stall maybe 3800.

    get the gears, put the truck on the dyno then pick your stall from peak torque
    Simple: 408 on steroids!

    I plan on picking up some 4.30 s with a max tire diameter of 33. I will most likely pick up a truetrac when I do them since it's one last thing to worry about.

    Most sports require one ball, motocross requires two.

    Racing isn't a matter of life and death, it's much more important than that.

    With that much split on that cam it is going to love spray. Get your gears swapped then see how you feel, because those 3.42s are killing you especially down low. Then you can start rethinking other parts, but start with the weakest link. I think 4.30s will be a nice happy medium.

    4.56's on 33's will be the same ratio to the ground as my 4.10's on 30's. I wouldn't do anything below 4.56 especially being a 4.8. And as far as converter I would go 3400+ and no bigger than a 258mm

    I was really thinking 4.30s but i dont want to be let down when I get it done so I will move to the 4.56. I really have been thinking alot about F/I or nitrous and depending on how it runs after the gears and the stall I may supplement it for special occasions. The only thing I dont like about nitrous is it runs out....
