How much HP can a stock 700R4 in decent shape handle before it self destructs?

Transmissions dont "take" horsepower but TORQUE. And a stock transmission can take up to about 400 lb. ft. as far as I know.

If I plan on making more than 450ft.lbs., what automatic trans should I consider?

Check out transmissioncenter.net. I am going with one of their "Raptor" 700R4 trannies. They claim up to 600hp, and are very personable people. The price isn't to bad either.
