Product Details

If you're building a street/strip Ford with a 351 Cleveland, 351 Modified, or 400 Modified engine, this COMP Cams Magnum camshaft is a solid choice for unlocking more power. It's designed to work with a hydraulic roller valvetrain, offering improved performance and durability over flat tappet designs. This camshaft is intended for applications that already have higher compression ratios, an aftermarket intake manifold, and headers, meaning it's part of a system built for more aggressive driving.

For this camshaft to perform as intended, you'll want to pair it with a 4-speed manual transmission or an automatic transmission with a 3000 RPM stall converter, along with a rear gear ratio of 4.10 or lower. These specifications help keep the engine in its power band, especially during spirited driving or track use. The 245/245 duration on both intake and exhaust sides indicates a camshaft that's well-suited for a wide range of performance modifications, providing a noticeable bump in horsepower and torque.

This camshaft fits a variety of Ford vehicles from the late 60s through the early 80s, including popular models like the Ford F-150, Ford Mustang, and Mercury Cougar. It's important to note that this camshaft is not CARB approved and cannot be shipped to California. Ensure your vehicle's setup aligns with the recommended specifications for optimal performance and longevity.
