AMC 290-401 Hydraulic Cam - 270H

The AMC 290-401 Hydraulic Cam - 270H from COMP CAMS is a precision-engineered hydraulic roller camshaft designed specifically for classic AMC V8 engines ranging from 290 to 401 cubic inches. This camshaft is ideal for automotive enthusiasts and professional mechanics who seek reliable, street-friendly performance while ensuring durability and engine longevity.

The hydraulic design of the camshaft eliminates the need for solid lifter conversions, simplifying installation on stock or mildly modified engine blocks while maintaining OEM-level reliability. The 270H designation indicates a moderate lift and duration profile that is optimized for mid-range torque delivery and improved throttle response. COMP CAMS employs a meticulous manufacturing process to ensure tight tolerances on lobe profiles and bearing surfaces, contributing to consistent valve actuation.

This camshaft is particularly beneficial for owners of vintage AMC models such as the Javelin, Gremlin, Rebel, and Ambassador, who desire increased power without the need for extensive frame-off restorations or complete engine rebuilds. Proper installation requires verification of valvetrain geometry, timing chain inspection, and lifter pre-oiling to ensure optimal performance.
