The Speedmaster PCE281.1728 is an aluminum bare cylinder head designed for Mopar and Chrysler big-block 383 and 440 engines. Featuring 265cc intake runners and 74cc combustion chambers, this head is engineered to support improved airflow and efficient combustion for performance-oriented builds on compatible B and RB series big-block applications.
Constructed from aluminum for reduced weight compared to cast-iron factory heads, this bare cylinder head allows builders to spec their own valvetrain components for a fully custom assembly. Whether you are refreshing a classic muscle car powerplant or building a high-performance street or strip engine, the PCE281.1728 delivers a strong foundation for your Mopar big-block project.
