I have a the disassembled 327 that came with my K5 taking up room in the garage. When I pulled the motor out, I figgered I could rebuild it someday down the line. It's supposedly one of the high nickel blocks, 4 bolt main, and I've never built a SBC before. BUT, the thing is, it's already been bored .060 over. I had some minor compression issues, but that may have been due to the fact that a couple of the piston rings came off in two pieces when I pulled the pistons out. The bores show no signs of scoring, could I just re-hone? Is .060 the max that a cyl. can be bored out? Should I hang onto this block, or list it as a lost cause?
