now would these be able to stand up to that kind of power? would i need any other parts like an input/output shaft or aftermarket sprag?
id like to use a 4l80e with a transgo hd2 shift kit and converter but i figure i can do the th350 for considerably less since i already have the th350 and a 4l80e converter alone would be $850ish on top of the $300 or so id pay for a good trans and $150 for the shift kit
