Product Details

This COMP Cams XE266HR10 camshaft features a 212 degrees intake duration and 218 degrees exhaust duration at .050 inch lift. It's a hydraulic roller camshaft designed specifically for Chevrolet 348 and 409 engines. This camshaft is a solid choice for building a street cruiser that still offers good throttle response, especially in the 409 engine, while maintaining a relatively mild idle quality.

The Xtreme Energy line from COMP Cams is well-known for providing noticeable improvements in performance. This particular grind, the XE266HR10, balances power with drivability. Its hydraulic roller design means it operates with less friction than flat tappet cams, contributing to better valvetrain longevity and potentially more consistent performance over time. While it offers improved throttle response, it's engineered to keep the idle quality mild enough for comfortable street use, making it a popular option for those looking to enhance their classic Chevy's performance without sacrificing too much comfort.

It's important to note that this camshaft is not CARB approved and cannot be shipped to California. When installing a new camshaft, always refer to the manufacturer's detailed installation instructions to ensure proper setup and to achieve the best results for your engine build. This camshaft is a significant upgrade for your 348 or 409 engine, aiming to provide a more engaging driving experience.
