Putting 270 ft lbs in the back, stick with stock tranny?

you might be able to get a 901 built up properly to handle your horsepower, but it will definitely cost you more then using a stock 901.

Or you can build up a T1 case using all aftermarket gears and aftermarket ring and pinion too. You could also add a Berg 5 kit all depends on what kind of money you want to spend.
