Replacing casings after losing a rod through the cases. Found a good set of cases. It has a stroker kit in it by Cray Craft. Split the case and I don't like the end play on the rod. He clearanced the cases for a 727 stroker kit. Issue is he ground down the stampings off the rod and piston. The piston is a CP with xp104 under the bottom but the part number was ground off the pin goes. And there is no number on the rod. I was unsuccessful finding him to discuss. Any suggestions?
