Now comes the .50 cal :-)


One thing to remember is that horsepower isn't what breaks transmissions; torque is.

He (corvette) isn't running a TH400; He's running a TH700R4 which is good to around 300 ft/lbs of torque without being built, built it can do around 500 ft/lbs. That being said a friend of mine had a built TH700R4 behind a 383 and would regularly brake the bell housings off at the transmission, eventually we got a good bell housing that held up and the transmission grenaded.

I'm not sure how much torque a turbo 6.5 makes; but I bet it's a good bit.

I'm still not sold on STS kits; I've driven a trans am with one and I just don't feel right about it even though it all works just fine.
