This is a knuckle motor that came with a basket case my daddy bought last summer. It has .40 over FL cylinders. The wrist pin bushings were wore out. Here is a pic of the piston twisted all the way over. Surprisingly the cylinders were not scored at all, the bores were glassy smooth. Everything must have just centered up and ran!
I marked the piston and cylinder alignment with a paint marker. This is a pretty neat deal, I have never seen wrist pin bushings so worn out.
