Edelbrock Musi 555 C.I.D. 697 hp Pro-Flo 4 long block crate engines are powerful, big cubic inch packages featuring the ultra-efficient Edelbrock E-CNC cylinder heads. The heads are ported where it counts to achieve optimal airflow for maximum horsepower and torque in high performance street and light-duty racing applications. The key advantage of these cylinder heads is their increased airflow for big power, and the exhaust port exits are in the stock location, which allows for the use of readily available off-the-shelf headers.
