364 ci Chev LS2 – DishTop Hypereutectic Pistons364 c.i., 4.000″ bore, 3.622″ stroke, 6.098″ rod length, -7.0ccdome volume
Brand: SPEEDPRO
Part Number: SPH857CP STD
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 minimize 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 pistonsto 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
