What are yalls thoughts on either the Namura Piston or a Wiseco Piston? Ill need to get some pictures up, but i have major grooves on the stock piston now and also, when i took out the piston. The wrist pin just slid right out, there must not have been a pin holding it in place. I also noticed that the wall inside the jug was a bit different. I'm sure it was from the wrist pin, which made a nice groove on one side and then looking at the other side. It looks as if it was actually machined that way. Needing much help here! Thanx everyone in advance
