This really pistons me off! I always thought they were better than the stuff Keith Black/Silvolite turns out ,but there's several sets of Speed Pro Forged and Hyperutectic pistons on E-Bay right now that look nothing at all like Speed Pro products ( for 350 SBC ). Hardly no skirt and very little pin boss support. I thought they were just someone trying to sell junk off as Speed Pro, but maybe it is Speed Pro after all.
Auction #'s: 190170565437, 190170910741, 190171597095 if interested.
