The 39 box will work fine - the question is for how long! LOL.

It all depends on the application, how sticky the tires are, if he drives it hard from a dead stop, etc.. As Charlie mentioned, if you pay particular attention to clearances, bearing fitment, 2nd gear bushing fitment, find new cluster shafts, etc - then these boxes can take some level of abuse. Now 350 HP and a heavy foot . . . will be fun for awhile (ask me how I know these things!).

I totally agree on the Columbia . . . unless you spend at least a couple thousand on special parts - and know all the weak points.
