The Wiseco K477B105 is a Professional-grade Quick 16 Series forged piston set engineered for Big Block Chevrolet 582 cubic inch engines. Featuring a semi-hollow +40cc dome, 4.605 in. bore, and a 1.060 in. compression height, these pistons are purpose-built for high-performance street and drag race applications using 24° conventional cylinder heads.

Forged from 2618 high-strength aluminum alloy and precision-machined at Wiseco's Mentor, Ohio facility, each piston delivers the tensile strength and thermal resilience required for serious power builds. The semi-hollow dome design optimizes combustion efficiency while reducing reciprocating mass.
