Anyone running a th400 in their a body?

I have a 727 that I run with 730 hp na then hit it with 175 hp of nitrous. Its on its third season took it apart, looks good so back together it goes. I have 2500 in my trans, how much do you have in your trans, floor and front end to make this work?
730 + 175 = 905. The OP was talking about over 1000 HP.
