Product Details

This COMP Cams CRB 306S-10 camshaft is a mechanical flat tappet design, intended for serious street and strip performance. It's built for Mopar B and RB series engines, specifically those with displacements like the 383, 400, 413, 426 Wedge, and 440. This camshaft is a solid option if you're aiming for significant power gains and are willing to make the necessary supporting modifications.

For optimal performance with this camshaft, COMP Cams suggests specific setups. For a 440 engine, you'll want a torque converter rated around 3500 RPM and an 800-850 CFM carburetor, paired with a compression ratio of 10.5:1 or higher. If you're running a 383 engine, the recommendation is even more aggressive, calling for a 4000+ RPM converter to effectively utilize the camshaft's powerband. This indicates it's designed for high-RPM operation and requires a robust drivetrain to match.

This camshaft is a well-built component for enthusiasts looking to push their Mopar V8's performance. It's important to note that this part is not CARB approved and cannot be shipped to California. Ensure your vehicle's setup can handle the demands of a high-performance camshaft like this one.
