What is the main benefit of a hydraulic roller camshaft over a flat tappet design?

Hydraulic roller camshafts generally offer improved performance due to reduced friction and better valvetrain stability. They also tend to have a longer lifespan and require less maintenance than traditional flat tappet camshafts.

Does this kit include everything needed for installation?

This kit includes the camshaft, lifters, assembly lube, and decals. It is recommended to also have fresh engine oil and filter, and to consult the manufacturer's instructions for any additional hardware or fluids that may be required for your specific application.

What is the intended application for the XR270HR-1 camshaft?

The XR270HR-1 camshaft is part of COMP Cams' Xtreme Marine line, meaning it's designed for a good balance of performance and drivability in applications like boats or street-driven vehicles that benefit from improved throttle response and power band.

Product Details

If you're looking to wake up your older Chevrolet small block engine, this COMP Cams Cam & Lifter Kit is a solid option. This kit is built around the CS XR270HR-1 camshaft, which is a hydraulic roller design. Hydraulic roller camshafts are known for their improved performance and reduced friction compared to older flat tappet designs, and this one is specifically tuned for the Xtreme Marine line, offering a good balance of power and drivability for a range of applications.

This kit includes everything you need to get started: the camshaft itself, a set of matching hydraulic roller lifters, assembly lube to ensure proper break-in, and decals. It's designed to work with '87 and newer General Motors small block V8 engines (305-350 cubic inches) that originally came with a factory roller camshaft. This means you're getting a well-built component that's engineered to integrate with your existing valvetrain setup, avoiding the need for extensive modifications. The camshaft specifications, with a 218-degree intake and 224-degree exhaust duration at .050 lift, are chosen to provide a noticeable improvement in throttle response and power band without making the engine too choppy or difficult to manage in daily driving or marine use.

This kit fits a wide variety of Chevrolet and Buick vehicles from the late 80s through the mid-90s, including popular models like the Chevrolet Camaro, Corvette, C/K trucks, and Buick Roadmaster. It's important to note that this camshaft 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 the longevity and performance of your new camshaft and lifters.
