COMP Cams Camshaft A8 287T H-107 T Thumper

COMP Cams is well-known for making performance valvetrain components, and this Mutha' Thumpr camshaft is a prime example of their work for AMC V8 engines. This hydraulic flat tappet camshaft is designed for high-performance street and strip applications, giving your AMC 290, 304, 343, 360, 390, or 401 cubic inch engine a noticeable bump in power.

This camshaft features a 235/249 degree intake/exhaust duration at .050 lift, which contributes to its aggressive nature and the characteristic rough idle you'd expect from a performance cam. To get the most out of this cam, you'll need to ensure your engine has at least 9:1 compression, a 2500+ RPM stall torque converter if you have an automatic transmission, and you should plan on upgrading your intake, gearing, and exhaust headers. It’s a solid option for building a powerful AMC V8 for weekend cruising and occasional track use.

This camshaft fits a wide range of AMC and Jeep vehicles, including models like the Jeep CJ5, Jeep Cherokee, and American Motors AMX. Make sure to check the full fitment list to confirm it's right for your specific application.
