Draker Posted February 18 Report Share Posted February 18 I’ve dropped an L20b at the machine shop to find out what needs done. I know at a minimum it’ll need pistons due to a ring ridge at the top of all cylinders. I’m guessing 40 over? The problem is the machine shop is unable to locate replacements. I’ve done some digging (Jason grey post) and found some potential options from an L28 at 86mm. Maybe something from a z20. My problem is really sourcing the pistons.. seems like everything has dried up, including rock auto. eBay is looking promising, but quality seems like a big question mark?? The goal for this motor is to just be reliable. minor performance gains are appreciated, but not looking for a high compression build. More displacement is good, slightly higher compression is also fine. Not looking to be a race fuel build. any recommendations, or parts sources? Quote Link to comment
