Dual Energy 219/229 Hydraulic Flat Cam for Chevrolet Big Block 396-454 | CCM11-209-4

The COMP Cams Dual Energy Camshaft (11-209-4) is engineered for street applications where a balance of power and efficiency is key. The Dual Energy design features more exhaust duration and lift than intake, making it an ideal choice for engines using factory restrictive exhaust ports or full-length exhaust systems. It offers a flat torque curve, which translates to great streetability while providing a significant boost in mid-range and upper-rpm horsepower.
