Well I have finally put my motor in and my clutch chatters. I did not put a new throwout bearing in "wish I did". So here is the big question since I have to pull the tranny off I was just going to replace the old stock clutch.So which clutch is the better buy the Petro works performance clutch or the center force dual friction clutch.I have stock rims tires but the new motor is 10.2 high compression and rv2 cam all from sammypro. I did not mill the motor at all it is still all standard sizes. So let me know which is better Petroworks clutch or Centerforce clutch.
