wrist pin perhaps? has there been a prior rebuild?
edit: Upon further investigation, I know I'm wrong... the scrape is in the wrong position... I'm putting my vote on broken ring...

the pistons are fairly clean engine only about an hour of runtime, I'm figuring a ring as well. I have a NA motor I'm going to use with my perp drilled crank and re-sized rods on the NA pistons.
