I scraped and scraped and could not find any overbore number stamped on the top of the piston. Is it possible it is a standard bore with performance parts??? I'm also trying to pinpoint the year. Could this be a '53 or '54 (ie pre bent 8? dirt tracker???) I have enough door stops that I dont need another, but if I have a rare find - what the hell, lets rebuild it and get it on the street and in Hop Up Annual - it belongs there!! So I ask you HiTork, is this junk? Any other thoughts, anyone?
