COMP Cams Camshaft CS 281Tk-R6

If you're building a Chevrolet Small Block for oval track racing, this COMP Cams CS 281Tk-R6 solid roller camshaft is designed to give you the performance edge you need. It's specifically tuned for limited late model applications, working well with 2-barrel and 4-barrel carburetors, and is intended for engines ranging from 331 to 355 cubic inches. This camshaft fits a wide variety of Chevrolet Gen 1 Small Block engines, including popular displacements like the 350, 327, and 283, but it's important to note it's not compatible with factory roller blocks from 1985 and newer or LT1/LT4 engines. For those building a classic 1955-1957 engine, be aware that these earlier models require a specific oiling groove on the rear journal, which this particular camshaft does not have; you'll need to contact us directly for a cam with that feature.

This camshaft features a solid roller design, which generally allows for more aggressive profiles and higher RPM operation compared to flat tappet cams. The lift and duration figures are optimized for competitive oval track use, aiming for strong mid-range power and a broad torque curve suitable for sustained racing. COMP Cams specifies that this camshaft must be used with a melanized or nitrided distributor gear to prevent premature wear and ensure proper function; using cast or steel gears without these surface treatments will void the warranty.

When installing this camshaft, it's crucial to confirm your engine's original configuration. Many trucks and SUVs retained flat tappet camshafts well into the 1990s, while performance cars like Camaros and Corvettes transitioned to roller cams earlier. You may need to remove the intake manifold or timing cover to verify whether your block is factory roller or flat tappet. This camshaft is not CARB approved and cannot be shipped to California.
