I have a set of cylinders that are ported and polished, however they need to be rebored. They are on stock bore right now, looking to sell them, how much are they roughly worth, I don't want to put a rediculous price out there, and I know I can't list it and ask for people to shoot me an offer either, so I thought I would see what everyone else felt they may be worth. I would imagine they are going to have to be bored between 20 and 40 over. Appreciate any info.
