COMP Cams Camshaft Kit CS 280XFI HR-13

This COMP Cams CS 280XFI HR-13 camshaft kit is built around an XFI 230/236 hydraulic roller camshaft, a design choice that significantly reduces friction and allows for more aggressive valve lift compared to older flat tappet designs. This kit is intended for "hot street" applications, meaning it's designed to give you a noticeable performance edge on the street while still being manageable for daily driving, though it will likely change your idle characteristics. To get the most out of this camshaft, you'll want to ensure your intake manifold and exhaust system are also upgraded to handle the increased airflow. A stall converter of 2500 RPM or higher is also recommended to keep the engine in its power band during acceleration.

When you choose this K-Kit, you're getting a comprehensive package that includes everything you need to swap in a new camshaft and optimize your engine's valvetrain. Inside the box, you'll find the camshaft itself, a set of hydraulic roller lifters, matching valve springs, retainers, and valve locks to ensure proper valve control. It also comes with valve stem seals to prevent oil from entering the combustion chamber, a timing chain set for accurate camshaft phasing, and assembly lube to get everything started smoothly. This kit is designed for Chevrolet Gen 1 Small Block engines, covering a wide range of displacements from 262 to 400 cubic inches. It's important to verify your specific engine is a flat tappet block, as this kit is not compatible with factory roller blocks from 1985 and newer, nor is it for the LS-based engines.

This kit is a substantial upgrade for your Chevrolet Small Block, offering a significant bump in performance for those looking to build a potent street machine. While it's designed for a wide array of vehicles, including many trucks and older performance cars, always double-check your engine block's configuration to confirm compatibility. For those with a 1955-1957 Chevrolet 265 engine, a specific oiling groove on the 5th cam journal is required; contact us if you have this particular application.
