COMP Cams Camshaft CS 268A-R10

COMP Cams is well-known for performance engine components, and their Magnum series camshafts are a popular choice for builders looking to get more out of their Chevrolet Small Block engines. This CS 268A-R10 solid roller camshaft is designed for Chevrolet Gen 1 Small Blocks, fitting a wide range of displacements from 262 up to 400 cubic inches. It's a versatile option that provides good vacuum, excellent throttle response, and a noticeable idle, working well with stock manifolds and torque converters rated for 2000 RPM and higher. This camshaft is optimized for use with Melanized or Nitrided distributor gears; using cast or steel gears without similar surface treatments will void the warranty.

This solid roller camshaft offers a 224-degree intake and 224-degree exhaust duration at .050 lift, making it a strong performer for street and strip applications. It's important to verify your engine's configuration before installation. This camshaft does not fit LT1/LT4 engines or factory roller small blocks from 1985 and newer, as GM gradually introduced roller camshafts into many engines during that period. You'll need to remove the intake or timing cover to confirm if your block is a factory roller or a flat tappet design. Additionally, 1955-1957 Chevrolet 265 engines require a specific oiling groove on the rear journal, and this particular part number does not fit those early models. If you have one of these specific early engines or are unsure about your block's configuration, please contact us for assistance.

For optimal performance and to maintain warranty coverage, it is crucial to use a Melanized or Nitrided distributor gear. Using incompatible distributor gears can lead to premature wear and will void the warranty. This camshaft is a significant upgrade for those looking to enhance their classic Chevrolet V8's performance, offering a noticeable improvement in power and responsiveness.
