Product Details

If you're looking to get the most out of your Chrysler 383 or 440 big block for street performance, this COMP Cams solid roller camshaft is a serious contender. This camshaft is designed to work hard on the street, offering a significant bump in performance when paired with the right supporting modifications. It's built for those who want to push their engine's capabilities beyond stock, especially in applications where aggressive street driving is the goal.

This is a Magnum 262/262 solid roller camshaft, meaning it has a 262-degree intake and 262-degree exhaust duration at 0.050 inch lift. The solid roller design allows for more aggressive lobe profiles and higher lift, which translates to better airflow and more power. For the 383 engine, you'll want a torque converter rated for 4000+ RPM, a 750-830 CFM carburetor, and rear gears in the 4.30-4.88 range. If you're running a 440, COMP Cams recommends a 3500+ RPM converter, an 800-850 CFM carburetor, headers, and rear gears between 4.10 and 4.56. Remember, a solid roller camshaft requires a specific distributor gear upgrade to prevent premature wear.

This camshaft fits a wide range of Chrysler B and RB series engines, including the 383, 400, 413, 426 Wedge, and 440. It features a 3-bolt camshaft design for secure installation. While this cam is built for maximum street effort, it's important to note that it is not CARB approved and cannot be shipped to California. Ensure you have the necessary supporting components like a strong valvetrain and proper tuning to take full advantage of this camshaft's potential.
