Selling a set of Probe Forged SRS flat top pistons for 347. They are part number 10660-030. You can look up the full specs on Probe's site but some of the specs are -4cc flat top pistons, has valve reliefs for inline and twisted wedge heads, .912" wrist pin and 1.090 compression height. These only have a few hundred miles on them and are in great shape. CHP sells them for $499 new. I'm looking to get $400 obo for them. They are currently at a machine shop being removed from the rods. Would also sell the rods for an extra $200 also. They are CAT Forged H-beam rods. 2.123" rod journal and .912" wrist pin. You can check my feedback on the corral.net under the same name since I don't have any feedback on here.
