Product Details

This COMP Cams Mutha' Thumpr camshaft and lifter kit features a 235/249 degree hydraulic roller design, specifically tuned for Ford 429 and 460 Big Block engines. It's built for high-performance street and strip applications, requiring a minimum of 9:1 compression and a 2500+ RPM stall speed torque converter to operate effectively. This kit is designed to work with upgraded intake systems, gears, and headers, and you can expect a noticeable, rough idle characteristic that signals its aggressive nature.

The kit includes the camshaft itself, a set of hydraulic roller lifters, assembly lube to ensure proper break-in, and decals for your engine bay. COMP Cams is a well-known name in performance engine building, and this kit represents their focus on delivering significant power gains for enthusiasts looking to push their Ford Big Block beyond stock capabilities. The hydraulic roller design offers improved valvetrain efficiency and durability compared to flat tappet setups, allowing for more aggressive cam profiles and higher RPM operation.

To get the most out of this cam, ensure your engine is prepared with the necessary supporting modifications. This includes an appropriate intake manifold, exhaust headers, and a torque converter with a stall speed above 2500 RPM. Proper tuning and a compression ratio of at least 9:1 are also crucial for optimal performance and reliability. This kit fits a wide range of Ford and Mercury vehicles from the late 60s through the late 70s, including models like the Ford LTD, Mercury Marquis, and Lincoln Continental.
