COMP Cams Camshaft FW 299T HR-107 BMT T

When you're looking to significantly boost the performance of your Ford 351 Windsor engine, this Big Mutha' Thumpr camshaft from COMP Cams is a popular choice. What you get in this package is the camshaft itself, ready to be installed into your engine. This isn't a mild upgrade; it's designed for street/strip applications where a noticeable increase in power and a more aggressive engine note are desired.

This hydraulic roller camshaft features a 243/257 degree intake/exhaust duration and a 107-degree lobe separation angle. To really make this cam perform, you'll need to ensure your engine setup can support it. That means aiming for at least 9.5:1 compression, a torque converter with a stall speed of 2800 RPM or higher, and a good intake manifold, appropriate gearing, and headers. Expect a very rough idle with this camshaft; it's part of its aggressive character and a sign that it's breathing deep.

This camshaft fits a range of Ford vehicles originally equipped with the 'Old' firing order and 351 Windsor engines, including models like the Ford Bronco, F-150, and E-Series vans. It's a solid option for builders looking for a significant power increase and a distinctive sound, but be prepared for the supporting modifications and the aggressive idle it brings.
