You would probably be better off getting a Pro-Built 700R4. If you still wanted to get rid of the 700R4, I'd go with a TH350 instead of a TH400. They're lighter, take less power to run and when properly built they can handle the power you're talking about. Spohn sells crossmember and torque arms for the conversions and you'll probably have to get a driveshaft made which shouldn't be too much. Really all comes down to what you're going to be doing with the car.
