COMP Cams Camshaft Set F4.6 3V Mod. Th2

This is the COMP Cams Thumpr NSR camshaft set, part number 127010, designed for Ford 4.6L and 5.4L 3-valve Modular engines. If you're looking to get more out of your engine, this camshaft upgrade can offer a noticeable improvement in power and torque, especially in the mid-range and above 4500 RPM, while still maintaining a good idle. It's a popular choice for owners of vehicles like the Ford Mustang, F-150, Expedition, and Lincoln Navigator who want to enhance their engine's performance.

This hydraulic roller camshaft features a 226/246 duration profile, which is engineered to work with your stock valve springs, converter, and gears, simplifying the installation process. However, to get the most out of this camshaft and ensure proper operation, it requires a cam phaser upgrade and custom engine tuning. This combination allows the camshaft to perform optimally, delivering those sought-after power gains without sacrificing drivability.

When installing this camshaft, remember that it's not CARB approved and cannot be shipped to California due to emissions regulations. It's a substantial upgrade that changes the engine's breathing characteristics, so proper tuning is essential for both performance and longevity. Make sure you have the necessary supporting modifications, like the cam phaser upgrade and tuning, ready before you begin the installation to ensure a smooth and successful build.
