Running KB Claimer pistons .465 dome true 14-1 comprssion (alky). Engine is down on power, did compression test cold and only had 150 psi. So i warmed the engine and it dropped to 120 psi!!! Shouldnt it easily be 200-220? With these pistons/alky/bore the ring end gap factor is .03248 comp ring gap which i set at .033. Engine has 7 races on it but only 2 since it sat for 3 years. Im guessing the rings are gone? Anyone else run these pistons/have this issue? Thanks
