I have a set of 8 JE dish pistons, custom made to work with SCJ heads. They measure 4.44 on the skirt. They are used, and come out of an airboat engine. We built a new motor with smaller bore. So we don't need these pistons any more. If you can use them, I would like to sell them. My mechanic and the machineshop we work with says they are in great shape. I don' know what they are worth, so I guess I would like to see if anyone wants to make an offer. My name is Wayne and you can call me at 402-867-2226 in Nebraska if you need more info.
