Product Details
This COMP Cams Mutha' Thumpr camshaft features a 235/249 degree intake/exhaust duration at .050 lift, a common specification for aggressive street and strip performance builds. It's designed for Ford 351 Windsor engines, specifically those originally equipped with the "Windsor" firing order. This camshaft is a significant upgrade for enthusiasts looking to extract more power from their engine, but it requires supporting modifications to perform optimally.
To get the most out of this camshaft, you'll need a minimum of 9.0:1 compression, a torque converter with at least a 2500 RPM stall speed, an upgraded intake manifold, headers, and proper exhaust. Expect a rough idle, which is characteristic of performance cams of this size, indicating it's working hard to maximize airflow. The hydraulic roller design means it uses roller lifters, reducing friction and wear compared to flat tappet designs, allowing for more aggressive lobe profiles and better performance potential.
This camshaft fits a wide range of Ford vehicles, including popular models like the Ford Bronco (1981-1995), Ford F-150 (1981-1995), and Ford E-Series vans (1975-1995). It's important to note that this camshaft is not CARB approved and cannot be shipped to California. Ensure you have all the necessary supporting components and understand the rough idle characteristic before installation.
