I currently have my 200 six Block at the machine shop to be bored. I had planned on totally disassembling it before dropping it off complete with crank, cam and pistons. The shop said they would pull it apart for me and let me know how much I would have to bore it. They mentioned that they would also let me know if the crank needed to be polished. I'm no engine building expert so enlighten me on what polishing the crank does for me. I have assembled several engines in my time and have never had any work done on the crank but none of the engines have been in service as long as this one (Engine is out of a 68 Mustang). I know polishing is common on newer engines and high performance / racing engines due to the tight tolerances but is this something I need to worry about on my daily driver?
