Replacing clutch disc and rod bearings. In the course of diagnosing the the cracked compression ring, Pete removed the rod end. He found the top portion of the bearing to be worn to the copper while the bottom end appeared to be fine. No issues w the rod journals. He surmises that this may have happened at engine initial startup. The motor came out of the 92 Aqua ZR and was a service replacement to the original motor. Pete suspects that since the service motors may have sat for some time, the top portion of the rod bearing had drained of oil, and startup of the motor without proper pre-oiling may have caused the wear.
Also, I am replacing the stock LT1 clutch disc I have been using. I have suspected that possibly the clutch could be slipping at top end after having done a series of mods that should have resulted in an increase of trap speed. Instead the trap has remained relatively flat and really isn't indicative of the power the motor is making. The disc we have removed shows signs of wear and is pretty thin. Replacing it w Centerforce sprung hub which has more "meat" to it. As you can see in the attached pics, the CF disc utilizes more of the area in the center to increase friction surface and several others like the way it works with their Fidanza FW.

Is that the Camaro clutch disc Dom ?
