Hi Everyone: I'm restoring a 29 Commander with a straight 8. Problem: I picked up my engine block and parts from a machine shop that had the stuff for over a year and hardly got any work done on it. The pistons and wrist pins were removed from the connecting rods and he (the machinist) didn't know which way the pistons fit on the rods. I have since located a competent machinist and the block, crank, head, and cam are finished. The problem still remains as to which way the pistons fit on the connecting rods. There is a small oil hole on the crank end of the rods that faces either toward the front or rear. This hole points upward at an angle at the base of the rod where the "I" beam portion begins. Would appreciate hearing from anyone who can help me out on this. Thanks, Bruce.
