COMP Cams Xtreme Energy 4&7 Swap Camshafts 12-663-47

Smart engine builders understand the benefits of a 4&7 firing order swap camshaft, which exchanges the 4 and 7 camshaft lobe timing in small and big block Chevy engines. While some builders have realized significant horsepower gains, all of them experience the exceptionally smooth torque curve possible with this new firing order technology. Dyno, Spintron, and track-tested, these camshafts do not require any engine block, ignition, or valvetrain modifications and can be custom-ground to the engine builder's exact specifications. Regardless of the cam specs that you require, these camshafts are engineered to achieve the maximum power possible using advanced lobe designs.Brand: COMP Cams
