The dish design with -27.8 cc volume helps reduce the compression ratio, making this piston ideal for applications that involve forced induction (such as turbocharging or supercharging) or other high-performance builds where a lower compression ratio is necessary to prevent detonation. The 4.005-inch bore combined with a 4-inch stroke offers a balanced displacement suitable for boosting performance while maintaining engine reliability under higher power levels.
