SPEED PRO Hypereutectic Flat Top Pistons Set/8+MOLY Rings for Ford BB 460 .020

This item is for eight (8) .020 bore Speed Pro (Sealed Power) hypereutectic flat top pistons and a moly piston ring set (Hastings/MAHLE) for Ford 460ci big block V-8 engines. P/N (8) H535CP-020 + 2M598-020. These pistons may be used as a performance upgrade in 460ci engines originally equipped with dished pistons.

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.
