COMP Cams Camshaft CS 274Xo-8

If you're building a tight-track oval car or a street machine with a Chevrolet Small Block engine, this COMP Cams CS 274Xo-8 camshaft is a solid option. It's designed for engines in the 327 to 358 cubic inch range, assuming a 9:1 compression ratio, and offers good performance for both intake and exhaust flow. This camshaft is a popular choice for those looking to get more out of their classic Chevy V8.

This is a solid flat tappet camshaft, meaning it uses traditional lifters and requires proper break-in procedures to ensure longevity. The grind profile, with advertised durations of 244 degrees intake and 246 degrees exhaust, is tuned for a balance of power and drivability in its intended application. It's well-suited for engines running a 2-barrel carburetor setup, making it a versatile choice for a range of builds.

When installing this camshaft, remember that some early (1955-1957) 265ci engines require a specific oiling groove on the rear journal. This particular part number does not include that groove, so if your block is from that specific early range, you'll need to confirm your requirements. It's also important to note that this camshaft is not compatible with factory roller camshaft blocks, which became more common in the mid-80s and later. Always double-check your engine's configuration before ordering to ensure a direct fit.
