COMP Cams Camshaft Kit CB XR296H-R12

If you're looking to get more out of your Chevrolet Big Block engine, this Xtreme Marine Camshaft Kit from COMP Cams is a solid option. It's specifically designed as a hydraulic roller camshaft upgrade for engines originally equipped with flat tappet camshafts, like many 396, 427, and 454 cubic inch V8s. This kit is a popular choice for performance builds, especially in marine applications like jet boats where improved throttle response and power are key, and it's also well-suited for bracket racing.

This is a complete K-Kit, meaning it includes everything you need to swap out your old camshaft and get your engine running with the new setup. Inside, you'll find the XR296H-R12 camshaft itself, along with hydraulic roller lifters, valve springs, retainers, valve locks, and valve stem seals. It also comes with a timing chain set to ensure your engine's timing is spot on with the new cam profile. COMP Cams even includes assembly lube and instructions to help guide you through the installation process. The camshaft profile, with its 242 degrees of intake duration and 248 degrees of exhaust duration at .050 lift, is tuned for a good balance of power and drivability in performance applications.

This kit is built for performance and is a significant upgrade over stock flat tappet systems. It's important to note that this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for proper installation and break-in procedures to ensure you get the most out of this performance camshaft kit.
