COMP Cams Cam & Lifter Kit A8 287T H-10

This COMP Cams Mutha' Thumpr camshaft and lifter kit is built around a 235/249 degree hydraulic flat tappet design, a specific choice that impacts how the engine breathes at different RPMs. It's intended for AMC V8 engines from 290 to 401 cubic inches, covering a wide range of vehicles like the American Motors Javelin, Jeep CJ5, and Jeep J10, among many others. If you're looking to build a high-performance street or strip machine, this kit is designed to help you achieve that goal.

To get the most out of this camshaft, you'll need to ensure your engine setup can support its demands. COMP Cams recommends a minimum of 9:1 compression, a 2500+ RPM stall speed torque converter if you have an automatic transmission, and supporting modifications like an upgraded intake, rear gears, and headers. When installed, expect a noticeable, rough idle that signals its performance-oriented nature. This kit includes the camshaft, lifters, assembly lube, decals, and instructions to get you started.
