I have heard around 600rwhp. But it also depends how you drive. I think it can handle your setup with ease.

I had a stock 4L65E in the tahoe withh the radix at 6# and it was fine. I did tear it up by dropping the truck and changing the pinion angle too much. So I bought a built 65E and put it behind 9#'s of radix and 4:10/Eaton and no problems yet. I drive it like I stole most of the time.

A factory 65e will not last to long behind alot of power. Go ask that question on silveradoss.com they can telly oyu exactly at what point it iwll fail pretty much. There are few freak trans out there. I wouldnt trust it with anything more than bolt ons. If you spray it say bye bye to it or if you put FI on it. Putting a transgo hd-2 shift kit and servos with a decent size aftermarket cooler will make it live a longer and happier life but it wont last forever if you drive it hard.
