Though I seem to remember the TR3650 trans in my Mustang was rated at 350 lb-ft, though we had plenty of guys pushing 500lb-ft or more through them and they were (seemingly) OK.

Just a thought, but a component is only as strong as its weakest link. Maybe the clutch is the limiting factor?

This is what I was wondering... which part of the transmission is rated at 332 lb-ft...

The 4.6l SOHC GT engine makes 300 crank tq stock and dynos around 260-270 wheel tq. I had a 2001 that i ran up to a 150 shot on which takes it to at or above 400 wheel tq and I never had an issue. The stock clutches were very very good, as well.

Yeah, I know they were pretty stout. I had a 2003. Was your 2001 a T5 or TR3650? I think they made the switch (to TR3650) mid-year 2001.

I had the TR-3650. I had a late year built 01 (November). It seemed like the part that broke first on the TR3650s (when they did break) was the input shaft.

Yup, input shaft issues. That was really all I ever heard of. That and there was a TSB on the 2nd gear synchro.
