I recently spoke to a guy who has been doing Babbit bearings for 40 years and has never peened them. Nor does he have failures. He drills dimples into the cast iron into which the metal runs and act as a key to prevent the bearing turning in he block. I read a lot here about peening them but what is the consensus on keying them in? I have seen engines where that was done when last rebuilt decades ago so I know it works.
