When I 1st put my B'cuda together(years ago)it had a over cammed thrown together 383 and parts store clutch. Even with the weak motor the clutch didn't live long at all. I replaced it with a 10.5" dual friction Centerforce. It's still there only now it's behind a 470" low deck. The street BFGs don't stand a chance through the 1st,2nd and much of 3rd so I'm not worried about the clutch. Sticky tires may prove the clutch to be a weak link(along with a few other pieces...lol) but it's just a street beater so I'm happy with the Centerforce.
