Connecting rod.
1965 225, forged crank. I finished running my rods through my blast cabinet, and gave them a good inspection. I didn't catch it before, but I have one rod that has a different part number from the rest and looks newer. The engine has "been into" by the PO. 5 Rods are 220554s and the odd ball is a 1947952. Checking the weights of the rods, they range from 1.8 the lightest to 1.11 the heaviest (the 1947952 rod). The other rods average out to about 1.10.
The light rod looks as if someone had actually tried to add weight to it. I had planned on dressing the rods (and pistons) to get them all the same weight, thus having to match the light rod. The rod bolts will be replaced also. I'm now flipping a mental coin about replacing those two rods. Opinions appreciated.
