COMP Cams Nitrided Camshaft CS 285B-6

If you're building a drag car, puller, mud bogger, or an oval track machine with a Chevrolet Small Block engine, this COMP Cams CS 285B-6 camshaft is designed to give you excellent torque and a manageable idle. It's a solid flat tappet design that works well in engines ranging from 327 to 350 cubic inches, and it's particularly suited for applications needing around 10.5:1 compression and lower rear-end gears. This cam is known for its versatility, offering great torque for quarter-mile to 3/8-mile racing, and it pairs well with a 3800+ RPM stall torque converter or a 4-speed manual transmission.

The camshaft features a nitrided finish, which is a surface hardening process that significantly improves wear resistance and durability for the critical flat tappet lobes. This means it can handle the demands of performance use and contribute to a longer service life. COMP Cams has engineered this camshaft to be a strong performer for a wide range of Chevrolet Small Block Gen 1 engines, excluding factory roller blocks from 1985 and newer, as well as LS-based engines.

When installing this camshaft, remember to confirm your engine block is a flat tappet design, as many later model Small Blocks transitioned to roller lifters. For early 265 cubic inch engines from 1955-1957, ensure the 5th cam journal has the necessary oiling groove; contact COMP Cams for details if needed. This camshaft is a popular choice for enthusiasts looking to extract more performance from their classic Chevy V8.
