The dish design with -13.3 cc volume helps reduce the compression ratio, which is especially beneficial for builds involving forced induction (like turbocharging or supercharging) where lower compression is needed to handle increased boost. The 4.010-inch bore and 3.622-inch stroke provide a unique displacement combination, making it ideal for applications where a balance between power and engine durability is required under higher boost levels.
