I'm running the stock rear end in mine, with an FI (Megasquirt) stock 5.0L - so maybe 250 HP at the crank. I have a World Class T5 from a 2.3L 4 cyl Mustang in mine, which has lower gearing than the ones found behind the 5.0's. I find the gearing to be a little too low for my liking. I wouldn't mind getting some taller gearing.
I've heard that the stock rear ends will hold up, unless you start doing lots of burnouts and donuts etc. I'm surprised, given this, that yours has lasted, being a drift truck.
