I am running a Ford about the same HP have a Dual Disc. The Dual Disc doesn't disengage as clean kind hangs but if you change the angle of the slave move it up for a straighter angle it works great if you don't you get 5 or 6 trips on each clutch two of us in my group found this out the hard way simple fix clutch lasts well 3 seasons so far.I can post photo if you need. Single disk 6 puck works well just has 500lbs of peddle so a little hang up on disengage is nothing. Go at least stage 3 or 4 ether way. We have people running single and dual they will work fine. If you go dual disk fix the angle and save your self some time and a lot of money.
