These are trw thirty over 10 1/2 cr pistons. I bought a decent amount of small block parts and these where in the mix. They were on the rods. I would not use the clips, as they look like a cylinder wall destroyer. The guy I got them from was a locale racer until they closed the track in 2005.
I thought of them as scrap till I noticed what little wear they had. I really do not see any skirt wear, and I know of a 66 Valiant that with a hp 273 needed a rebuild. I do not need another car so maybe someone else can use them. Stored here in the desert since the 80's, I have not cleaned them or done anything else. 3/16 oil ring grove and compression groves are 5/64.
$100 set plus shipping.
I still have the rods if you buy pistons, $20. Rods alone $40, and $13.50 priority ship. Tim
