Ok, I'll start with a little background. I'm helping a buddy with his 53 Chief engine that he has someone start on 4-5 years ago and couldn't seem to finish. Long story short a lot of these parts were already bought and I have no idea of the provenece although I suspect they may be Eastern stuff. The problem I'm having is when I torque the crankpin nut up the forked rod drags slightly againts the inside of the flywheel at TDC. I pulled it back apart and checked it againts an original and the rod is thicker in that area. I'm thinking of taking a die grinder and remove a little material. Maybe .060 - .080.
Anybody run into this problem before?
