Strength of a stock 4r70w.

What are these rated for?

I've done a quick search among multiple forums. What I'm seeing is no more than 350-400 on a stock converter. If you want to go higher than that people are saying total rebuild with stronger clutches, bands, and valve body as well as a multi-clutch torque converter. People are saying the single isn't locking up and eating itself at 450hp.
