Speedmaster Chevy SBC 383 ci 5.7" Flat Top Forged Pistons PCE305.1010.05

The Speedmaster Chevy SBC 383 ci forged pistons are precision-engineered components designed for small-block Chevrolet 383 cubic-inch engine builds. These flat-top pistons feature a 5.7" compression height and 4.060" bore size, making them direct replacements for 383 stroker assemblies and custom performance engine applications. The forged construction provides superior strength and durability compared to cast alternatives, critical for high-rpm and high-load engine environments.

These pistons are engineered to exact dimensional specifications (1.425" pin diameter, 0.927" ring thickness) to ensure proper fitment and seal within your SBC 383 block. Flat-top design provides efficient combustion chamber geometry while maintaining compatibility with your existing cylinder head configuration. Ideal for hot rod builders, stroker engine assemblies, and performance rebuild applications where reliability and precision are essential.
