STD Flat Top Hypereutectic Pistons Sph405Cp STD suit Chrysler 360 V8
Product Information
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
- Application: Chrysler Mopar small block LA 360 C.I.D. V8.
- Bore (in): 4.000 in.
- Bore (mm): 101.600mm
- Piston Style: Flat top, with four valve reliefs
- Piston Material: Hypereutectic aluminum
- Compression Distance (in): 1.637 in.
- Piston Head Volume (cc): +10.00cc
- Wrist Pin Style: Press-fit
- Pin Diameter (in): 0.984 in.
- Piston Ring Thickness: 5/64 in. x 5/64 in. x 3/16 in.
- Quantity: Sold as a set of 8.
- Notes: DurOshield® coated piston skirt.
