The later 998/999 stuff is pretty tuff. I ran a near stock 998 behind a 401 AMC in my bracket car for 12 years and never broke anything. This was a high 8 149 mph car.
PM me if you want more info.

The weak link in the 904 is the rear sprag. If it goes, it will take out the rear drum and band also. ATI used to make a heavy duty sprag for the 904, but no longer. I doubt you would have trouble with either the input or output shafts.
