A 6.0 made 325 hp and 560 lb/ft at the flywheel, so probably 230-240 hp and 430-450 ft/lbs at the back wheels. A 250 rwhp cummins will probably be somewhere around 600-650 ft/lbs, at a lower rpm than the ford. 300 rwhp cummins will be around 680-750 ft/lbs. I am guessing more than 700-750 ft/lbs would be asking a lot of a stock clutch to put to the ground, provided you have traction. All I'm saying is if you expect a stock clutch to hold up to a 300 rwhp cummins below 2000 rpm, where the big torque is, it may or may not slip. Hard to say. And if it did slip a little below 2k rpm at full power, one could keep running a stock clutch at those power levels as long as one was careful in the lower rpms. I just thought I'd share my humble opinion BEFORE you put the motor in the truck.
It will be a nice truck when it is done.
