A stock 4L80e with a shift kit will hold 800whp. A brake makes things a little more complicated. You'll need to re-evaluate what the transmissions main purpose is and then decide how much you want to spend.

Primary street car I would 4L80e and footbrake the car. Mostly track I would probably go TH400 since you can get the same upgrades that you would also need on the 4L80e but usually a little cheaper.
