main Bearing wear
Hi guy's, I've got a couple of questions and would appreciate any help you can give me. Im rebuilding my 76 corvette motor and after pulling the crank I notice some wear on the bearings which Im sure is normal but the rear larger bearing appears to be worn a little more so than the other bearings. all rod and main journals look really good with the exception of the rear which has two small nicks that I can see but cannot feel. The rear bearing is not scratched but like the rest, there is some bearing face wear. Does the rear usually wear a little more than the rest? The pistons are 030 over and the rods and mains are 010 over. This motor has been sitting for the last 20 years but was supposedly rebuilt just before it was taken out. I don't know if the bearings were replaced but it sure doesn't look like it. Bill.
