/6 904 to sb 904

My trans guy say's for the money-like $65-the 6 cylinder torque convertor is the best. He claims its a few hundred rpms better than the V8 ones and just as strong. Thats what I have and its not no high stall by any means but I also have the 2.74 first gear and 3.91's in back and a ok 318 so I like how it takes off.
