Product Details
When you're looking to wake up the performance of your AMC V8, this complete camshaft kit from COMP Cams is a solid option. This kit includes the camshaft itself, lifters, valve springs, retainers, valve locks, valve stem seals, a timing chain set, assembly lube, and even decals and instructions to help you get it installed. It's designed for AMC 290, 304, 343, 360, 390, and 401 cubic inch engines, covering a wide range of American Motors and Jeep vehicles from the late 60s through the early 90s.
This is the Mutha' Thumpr 287T H-107 T camshaft, a hydraulic flat tappet grind intended for high-performance street and strip use. To get the most out of this camshaft, you'll want to ensure your engine has at least 9:1 compression, a 2500+ RPM stall speed torque converter if you have an automatic transmission, and that you're running a good intake, headers, and appropriate gearing. Expect a noticeable, rough idle that lets everyone know you mean business. COMP Cams is well-known for their performance valvetrain components, and this kit bundles everything you need to make a significant upgrade to your engine's breathing and powerband.
This kit is a comprehensive package for anyone serious about extracting more power from their AMC V8. Remember that this camshaft is not CARB approved and cannot be shipped to California. Always refer to the included instructions for the most accurate installation procedures and recommendations.
