COMP Cams Camshaft CS 47S 285Hxl R7 Ope

If you're hitting the track in an open wheel modified car and looking for a way to manage tire spin while still putting down serious power, this COMP Cams OWM T/C Series camshaft is worth a look. It's specifically designed for racing scenarios on 1/3 to 1/2 mile tracks, especially those with tight corners or heavier surface conditions. This camshaft aims to provide a broad torque curve that helps the chassis hook up smoothly, while still offering strong top-end horsepower without excessive tire spin. It's a solid roller design, which generally means more durability and higher performance potential compared to flat tappet cams.

This camshaft features a 4/7 firing order swap, a common modification in racing to improve exhaust scavenging and power delivery. It's intended for engines in the 327-358 cubic inch range with an 11:1 compression ratio, running on gasoline or alcohol with a 4-barrel carburetor. To get the most out of this camshaft, you'll need a good intake manifold and cylinder heads that can keep up with its performance capabilities. COMP Cams engineered this line for use with their Race Series valve springs and Endure-X solid roller lifters, so pairing it with quality valvetrain components is key to unlocking its full potential.

This camshaft fits a wide range of Chevrolet Small Block engines, including popular models like the Camaro, Caprice, and C10 trucks from various years. However, it's important to note that it does not fit factory roller camshaft blocks from 1985 and newer, nor does it fit LS-based engines. For 1955-1957 Chevrolet engines, a specific oiling groove is required on the rear journal, and this particular part number does not include it. Always confirm your engine's configuration before installation.
