How much Horsepower are you making?

I'm actually working on that myself too. I'm running a dode truck hemi flywheel and pressure plate and then a 70's clutch disc with the correct spline for my 833. Not sure about it yet because I haven't got the parts yet but the truck hemi clutch is 10.5" anso is the 70's unit so I'm hopinwith some dumb luck I can mate the 2.

I tried the Truck Flywheel in mine and it wouldnt fit inside the stock bell housing. I used the mopar performance one. I have done 2 Hemi 4 speed cars and used the Center force dual friction disk and had bad vibration problems. I thought it was the flywheel because the pressure plate and disk were from my 340 and had no problems. After taking the pressure plate with me to the machine shop just in case they told me that they dont even sell the centerforce anymore beacuse of the vibration problems they have and told me it was probably that and not the flywheel. Sure enough the flywheel was out .25 g and the pressure plate was out 50 g. I asked him why he thought the centerforce was fine in the 340 and not the hemi he said maybe it was because the hemi has a much lighter rotating assembly. I ended up buying a hays and all has been great since.
