COMP Cams Shaft Rocker SBC AFR 190-195-21

If you're rebuilding the top end of your Chevrolet Small Block engine, especially one fitted with AFR 190-210 heads, a shaft-mount rocker system like this one from COMP Cams is a serious upgrade for performance. This setup properly positions the rocker arm over the valve, which is crucial for efficiently transferring the camshaft's power to the valve train. By using a horizontal shaft as the fulcrum instead of a traditional stud mount, the system gains significant rigidity. This increased stiffness translates directly into better valve train stability, allowing your engine to rev more freely and make more horsepower.

The construction here is solid. You're getting rocker arms made from strong 2024 aluminum, paired with an 8620 hardened steel shaft. This combination is designed using advanced computer technology and has been tested in demanding racing conditions. The rigidity this system adds not only benefits the valve train but also contributes to overall cylinder head stability. The specific ratios included are 1.6 on the intake and 1.5 on the exhaust, tailored for optimal performance with the AFR heads mentioned.

This kit is a well-built component for anyone looking to maximize the performance potential of their SBC engine. It's designed to be a direct fit for the specified cylinder heads, simplifying installation compared to some other performance valvetrain components. Make sure to consult the manufacturer's installation instructions for proper setup and any specific hardware requirements.
