Description

These Wiseco dome-type forged racing pistons are designed for Big Block Chevy (BBC) engines, specifically the 454 CID, but are also compatible with 396, 427, and 502 BBC engines. They offer a 12.0:1 compression ratio (with a 118cc chamber), a 4.310-inch bore, and a 1.395-inch compression height. They are engineered for a 4.000-inch crankshaft stroke and 6.385-inch connecting rod length. Made from 2618 high-strength forged alloy, they feature an ArmorGlide skirt coating for reduced friction. The set includes eight pistons with .990-inch wrist pins; piston rings (1/16, 1/16, 3/16 inch) are sold separately.
