Black/chrome. High Compression engine. Engine comes with 10.8:1 CR flat top forged pistons and 640GP easy-start cams. If you prefer all out high RPM horsepower numbers; this high compression engine is the one. Engine is sold as ''Long Block''; meaning these are engines without any intake components or ignition. Any high performance intake system; that will fit a stock engine; will fit the S&S 124" since S&S specially machined the heads to compensate for cylinder length. Stock compatible air cleaners and breathers will also fit. Note: Sold as ''Long Block'' engine. Carburetor / throttle housing; manifold; ignition and charging system is not included. Note: A large throttle housing and high performance ECU is required for best performance.
