351W ci SB Ford – Flat Top Hypereutectic Pistons357 c.i., 4.030″ bore, 3.500 stroke, 5.980″ rod length, -12.0cc dome volume With 9.5 Deck
Brand: SPEEDPRO
Part Number: SPH336CP 030
Description:

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
