COMP Cams Camshaft CS 290Xo-6

This is the COMP Cams CS 290Xo-6 Oval Track camshaft, a solid flat tappet camshaft designed for Chevrolet Small Block engines. It's built for applications with 360+ cubic inches, 12:1 or higher compression, and a 4-barrel carburetor with good intake and exhaust flow. This camshaft is a popular choice for builders looking to get more performance out of their Gen 1 Small Block Chevy, fitting a wide range of vehicles like the Chevrolet Camaro, Corvette, and C10 trucks from the 1980s and early 1990s.

The CS 290Xo-6 features a 260 degrees of intake duration and 266 degrees of exhaust duration at 0.050 inch lift, with a .550 inch lift on both intake and exhaust. This profile is well-suited for engines that see a lot of track time or demanding street use where improved airflow and power are key. It's a well-built component that can make a notable difference when paired with the right supporting modifications like a good intake manifold and exhaust system.

It's important to confirm your engine's configuration before ordering. This camshaft does not fit LT1/LT4 engines, factory roller small blocks from 1985 and newer, or LS-based engines. Also, 1955-1957 Chevrolet 265 engines require a specific oiling groove on the rear journal that this particular camshaft does not have. Always refer to your vehicle's service manual or inspect your current setup to ensure proper fitment.
