Any body know why some small block chevy rods copper colored on the little end?
I just bought a set of reconditoned rods and one of them is like this. I've came across a few of these rods before and always wondered
why they did this just did'nt know who to ask. I have asked guys around here and just get funny looks.

Just a guess here, we send a lot of air hard die steels out for heat treat. Most of them come back with the copper-like finish. These steels are wrapped in a stainless steel foil during the processing. I think the rods that you see with the color have been through that type of heat treat.

A veteran engine builder who used to prep stock rods for us answered that question clearly by saying, " Think of that as 'rod bondo'." 4barrel is right, but that engine builder wanted to stay away from those rods with alot of that stuff as much as possible. Sometimes we would take in over a dozen rods so he could try to find eight acceptable ones.
