If it's clean it might be worth more if it saves someone from buying a whole set and overboring their engine. Joe sold me a set of 6 nice stock bore pistons for the aforementioned $5 each 15 years ago. I ran them 23,000 miles and they just keep humming along. At that time I couldn't get stock bore ones from Mahle and I didn't want to bore the block after only 65,000 miles. The engine is sitting on the garage floor during restoration and I am having a hard time deciding if it is time to bore it or not?
