Steven at 42autosports does a mild build and helps with programming of the 8l90e. He adds some clutches to a couple of the clutch packs and modifies the valve body. I know he is working on getting some upgraded clutch material.
These transmissions are really strong stock. I would expect it to last a long time at 650hp and probably wouldn’t bother with a build even at your higher goals at least until it fails.
