This is a brand NEW set of Big Block Chevy pistons.I'm selling them for a friend that had his short block together for over 10 years, and changed his mind to lower compression pistons..So, he took it apart and asked me to sell them for him.He said he paid $950 for them, so he could live with losing some money.He said he damaged the circlips getting out of the one side, so you will need 1/2 a set of those to use these pistons again, or maybe you have some around to use. Everything is in perfectly new shape, great high dome pistons..call me Mike 952-854-5 seven eight six...... here are the Piston Specs.
