so my clutch and tremec 3650 is just about done... ive got a aluminum driveshaft, aluminum flywheel and clutch waiting to be put in but while i have the tranny out i want to get a new one to put in considering i have over 400ftlbs of torque... what would i need to swap in a tko 500 or 600.. the 500 is 2100 and the 600 is only 100 bucks more
