COMP Cams 260-455 Oldsmobile Duration 276/282, Lift .505/.505 Hydraulic Roller Camshaft

This is the COMP Cams Xtreme Energy hydraulic roller camshaft, specifically designed for Oldsmobile 260, 307, 350, 403, 400, 425, and 455 V8 engines from 1967 and newer. If you're building a street machine and looking to wake up your engine's performance, this camshaft is a solid choice. It's engineered to provide a noticeable bump in power and torque, especially when paired with the right supporting modifications.

The Xtreme Energy series is known for its aggressive lobe profiles that help your engine breathe better. This particular cam features a duration of 276 degrees on the intake and 282 degrees on the exhaust, with a lift of .505 inches on both. These specs mean it's designed for improved airflow and cylinder filling, translating to more power. To get the most out of this camshaft, you'll need to ensure your engine is set up to handle it. That means headers are a must for better exhaust scavenging, low-ratio rear gears to keep the engine in its power band, and a torque converter with at least a 2200 RPM stall speed to match the cam's operating range.

When installing this camshaft, remember it's a hydraulic roller type, which generally offers less friction and more precise valve control compared to flat tappet cams. This can contribute to better performance and longevity. Make sure you have all the necessary supporting components ready, as this cam is intended for modified engines. It's important to note that this camshaft is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and break-in procedures.
