Carrillo BC1112-030 Small Block Chevy Dome Pistons Bore - 5cc 4.155

The Carrillo BC1112-030 is a high-performance dome piston set engineered for Small Block Chevy applications. Designed for serious engine builders seeking maximum compression and power output, these pistons feature a +5cc dome design optimized for 23-degree cylinder heads.

Key Specifications:

• Bore Size: 4.155 inches
• Stroke: 4.000 inches
• Rod Length: 6.000 inches
• Compression Ratio: 13.9:1 (with 62cc combustion chamber)
• Dome Volume: +5cc
• Head Compatibility: All 23-degree cylinder heads

Carrillo pistons are precision-machined from high-grade aluminum alloy and built to withstand extreme cylinder pressures and temperatures. The dome design increases compression ratio for improved thermal efficiency and power output, making these pistons ideal for high-performance street engines, race applications, and forced induction builds where maximum compression is desired.

Important Note: This compression ratio calculation is based on a 62cc combustion chamber volume. Actual compression ratio will vary with different chamber volumes, gasket thickness, and deck height. Professional engine building and proper clearance checking is recommended for all high-compression applications.
