SPEEDPRO SB 350 CHEV FLAT TOP PISTON

These ruggedly durable pistons are made with exclusive high strength FM425 alloy, and enhanced with 16.5% silicon for excellent tensile strength and scuff resistance. This advanced metallurgy permits tighter bore clearances, which help minimise noise on cold engine start-up. These pistons are the ideal choice for street performance applications and late-model replacement.

More Sealed Power hypereutectics benefits:

Higher strength than cast or forged at operating temperature Finely dispersed silicon particles provide a highly resistant wear surface and reduces scuffing Lower material growth allows pistons to be fit tighter, improving cylinder sealing for less blow-by and more power High silicon content allows elimination of groove inserts in certain applications Designed to retain standard ring gaps in the top groove Piston Specifications :
