If you haven't seen the new CP forged piston Jay Ivey developed, take a look. (Assuming the picture actually uploads for me!) The forging and machining are nothing short of exquisite and the finish is impeccable. Most significantly, these pistons represent a major net reduction in engine rebuild costs and make another contribution to long term reliability. They are supplied at minimum weight - no further balancing required - and without wrist pins. Just slide in your existing ones and snap in the Spirolocs!! Available from Ivey Engines and all your friendly FF1600 engine builders nationwide!!
