If you ask this question in an informational thread, I'm sure you'll get the answer you're looking for. However, this is a buy/sell/trade thread, so unless you're selling the motor here, you posted in the wrong place.

the traxxas kit should work....although you might have to grind down the motor mount braces so the engine will fit.

I used a american cnc big block kit on mine, I fit a modded surefire.32 in it, Check out the pic:cool:
