Show original supplier description
The COMP Cams Big Mutha Thumpr NSR camshaft is engineered for Ford 4.6L and 5.4L 3V Modular engines, including popular models like the F-150, Expedition, Mustang, and Navigator. This camshaft boasts an aggressive profile with 281 degrees of advertised intake duration and 314 degrees of advertised exhaust duration, paired with a .450-inch valve lift on both intake and exhaust. Its 109-degree lobe separation angle and 750-6800 RPM operating range are designed to deliver significant power gains. This camshaft set is designed to give your Ford 3 valve engine an aggressive, extremely rough idle, transforming it into a performance machine. It requires a stroker motor and/or ported heads for optimal performance. Major horsepower gains are achievable up to 6800 RPM, and it is recommended for use with 3.73+ gears and a 2500 stall converter (or 3000-3400 stall suggested for some applications). Extensive testing has confirmed repeatable power gains of 25+ rear wheel horsepower. Installation requires a cam phaser upgrade and custom tuning. Specifically, the COMP Cams Cam Phaser Limiter Kit (#5449) is necessary to safely modify the factory variable cam timing (VCT) system, allowing for aggressive camshaft lobe technology without losing VCT benefits. While compatible with stock valve springs, it's crucial to ensure proper tuning and phaser modification for optimal performance and durability.
