The dish design helps control compression ratio, and the -21.5 cc dish volume indicates a moderate reduction in compression, often used in high-performance builds that require adjustments for fuel type, forced induction, or to optimize the engine's overall power output. The bore size of 4.065 inches combined with a 4.125-inch stroke provides a well-balanced setup for performance applications.
