The dish design with a -30 cc volume reduces the compression ratio, which is particularly useful for applications involving forced induction (e.g., turbocharging or supercharging) where lower compression is needed to handle higher boost levels. The 4.125-inch bore and 4.125-inch stroke provide a balanced displacement ideal for performance builds, especially when optimizing for power and reliability under boost.
