The dish design with -27.8 cc volume helps lower the compression ratio, which is ideal for forced induction setups where reduced compression is required to handle higher boost levels safely. The 4.010-inch bore and 4-inch stroke provide a balanced displacement, making this piston ideal for high-performance applications that require increased power and reliability under boost.
