Wiseco K477B115 BBC Quick 16 Forged Piston 40cc Dome 1.060 CH

The Wiseco K477B115 is a forged aluminum piston designed for the Big Block Chevy (BBC) Quick 16 drag racing application. Featuring a 40cc dome and a 1.060" compression height, this piston is purpose-built to deliver consistent, high-performance results in bracket and heads-up racing classes governed by the Quick 16 format.

Wiseco's forged pistons are manufactured using a proprietary forging process that produces a denser, stronger grain structure compared to cast pistons — resulting in superior strength-to-weight ratio and resistance to detonation under high-cylinder-pressure conditions. The dome configuration increases the static compression ratio, making this piston ideal for naturally aspirated and power-adder Big Block Chevy builds where maximum cylinder pressure is desired.

Key Features:

• Application: Big Block Chevy (BBC) Quick 16 drag racing
• Dome Volume: 40cc positive dome for elevated compression ratio
• Compression Height: 1.060" for precise deck height and rod/stroke geometry compatibility
• Construction: Forged 2618 aluminum alloy for superior strength and thermal resistance
• Manufacturing: CNC-machined to tight tolerances for consistent ring seal and minimal friction
• Ring Groove: Compatible with standard BBC performance ring packages
• Finish: Includes Wiseco's ArmorGlide skirt coating to reduce friction and improve break-in
