My SBC is cursed! I've almost had it finished twice but keep finding something. On this tear apart I noticed that the new main bearings had wear on them even though the engine had never been run. Just cranked on while rebuilding. It looks like the flat colored coating is already wearing off. Is the wear in the pictures normal? And it seemed to be get worse towards the front. And yes I put breal in oil on them during install. The pictures are in order from front to rear. Thanks guys.
