Pick a clutch.....any clutch

Will a McLeod 75209 do the job? Used this in a 72 Cuda 416 . Not to the degree of a build you have but take a look.

I don’t think it’ll hold up for the OP’s application. It’s only rated to 500 hp. I run that clutch in my Duster behind a ~400 hp 340, it works well but I don’t think I’d put it up against 550 ft-lbs.
