I was just informed from Centerforce that the Centerforce dual friction clutch cannot handle the power of a Y-block. He asked me how much HP I had and from past experience I know better then to tell the truth so I doubled it to 1000 HP. He said that 500 is the limit. 500 was not a problem when I talked with them years ago and now 3 junk clutches later. I had the same experience with a driveshaft yoke that now has the splines twisted. I was assured at the time that I didn't need a Strange billet yoke for a 500 HP Y-block.
