Hello Members. I have for sale a set of V8 4-valve relief stock pistons which came from a 66 273. This set includes the wrist pins and retainer springs. I do not have the rods. The part number for these pistons is as follows: 2463265 which is found on the inside of the piston on one side. The other side carries a number as follows: 463266. I am asking $$ ten bucks apiece plus shipping and PayPal Fees. Please see enclosed pics. PM me at sgrip65 if you are interested. Thanks
