Carrillo BBC5111-060 Big Block Chevy Forged Dome Pistons 4.310 Bore

These pistons are engineered for serious performance applications requiring strength, precision, and optimal compression characteristics.

Key Specifications:

• 24.35cc dome design for increased compression
• 4.310" bore diameter
• Designed for 4.000" stroke
• 6.135" connecting rod length
• 9.8:1 compression ratio with 118cc cylinder heads
• Forged construction for maximum strength and durability

Carrillo pistons are precision-machined from aerospace-grade forged aluminum alloy, providing superior strength-to-weight ratio compared to cast pistons. The dome design increases compression for improved power output and throttle response. These pistons are ideal for high-performance street applications, drag racing, and other demanding motorsports environments where reliability under extreme conditions is essential.

The compression ratio specification assumes 118cc combustion chamber heads and the stated stroke and rod length combination. Actual compression ratio will vary based on final engine configuration including head volume, gasket thickness, and deck height.
