Am in the process of putting a TK0 600 in and found out that torque is what the suppliers are interested in, horsepower doesn't count much. With the high torque situation I have it required the TK0 600(600 ft lbs) and I'll add it's really pricey. I have heard rumors this trans might be in the late model supercharged stangs but would probably not be much cheaper from a salvage yard. After puking the whole bottom of the case on two rock crushers the price looks better and better.
