The FE will hold 500 hp. However like mentioned above, if you plan to do any sled pulling you need to go dual disc
2003 2500 HO 6spd, 500hp on the dyno in Muncie. Con FE now slips.
I am not trying to bash South Bend. I do think that they don't or didn't give a good explaination on there website which clutch is good for what hp or pulling and drag racing.
