SPEED PRO PISTONS
This item is for eight (8) .030 over bore Speed Pro (Sealed Power) hypereutectic flat top pistons with 2-valve reliefs and a cast piston ring set (Hastings/MAHLE) for Chevrolet 350ci (5.7L) small block V-8 engines. P/N (8) H631CP-030 + 139-030.
If you\'re looking for pistons with an unbeatable combination of performance and value, then Speed-Pro hypereutectic pistons are for you. These pistons are manufactured from aluminum alloy that contains 16 percent silicon for greater strength and wear resistance. They\'re also molded in the latest permanent-mold technology to ensure the precise fit and tight bore clearances that today\'s top engine builders demand. Hypereutectic pistons are ideal for use in high performance street, bracket, and oval track racing—and will work perfectly with normal ring end gaps.
