TF for a blower motor- or a Glide??

Ok Chris I need some input on transmissions for blown motors, I've got to tell you I'm very wary of high horsepower torqueflites, but what are thoughts on building a race trans to put behind a blown smallblock, figure around 1250HP and 900+ lbs of torque, it's all low RPM's though , the motor should never see much over 7000RPM.
Car weight will be around 2800lbs final gearing TBA?
I'll probably get an ATI blower converter, I've used that company a lot in the past and I've never had any problems with them-ah I neeed some bench racing tonight :mrgreen:
