Re: 302 Pistons
You have the ability to put them up for sale in the Classified section of the forum. Whether any one will consider buying it is a different question.
Pistons are a consumable (use once then scrap), as you generally rebuild with a larger bore piston to account for wear in order to get a good ring seal. There are over sized piston rings to rering an engine but it won't make power and suffers from ring flutter as well as excessive piston rock.
