454 ci BB Chev - Dome Top Hypereutectic Pistons467 c.i., 4.060" bore, 4.000 stroke, 6.135" rod length, +10.5cc dome volumeBrand: SPEEDPROPart Number: SPH426CP 060Description: 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 toretain standard ring gaps in the top groove
