how did 1 and 2 look? Did you build the engine? what were the clearances on the bad ones? Was the crank journal out of round? What do the journals look like? more engine specs please.

Short block was built at shop, a big shop not gonna name. Oil was said to be .003 clearance. dual line pick-up about 7200-7300 rpm. 1&2 look normal and mains show little wear. Im gonna have the crank checked and rods. just wanted input on what causes one brg next to the other wear so much more. The year before i ran this crank and had normal brg wear last year i upgraded to aluminum mains and had the shop build short block with new brgs
