COMP Cams Camshaft CB 305Qio10

COMP Cams has built a reputation for making serious performance engine parts, and this 4-pattern hydraulic roller camshaft is a prime example of their work. This isn't your average camshaft; it's built for engines that are heavily modified, whether you're setting up a street/strip machine or a dedicated bracket racer. It's particularly well-suited for larger displacement engines, like those 572 cubic inch and up, where more aggressive valve timing can really wake things up.

The camshaft features a hydraulic roller design, which means it's designed for smoother operation and less friction compared to flat tappet cams. The '4-Pattern' designation refers to its unique lobe design, offering a specific lift profile that's optimized for performance. With intake duration at 253 degrees and exhaust at 263 degrees (measured at .050 inch lift), this cam provides a significant increase in valve overlap, which is crucial for making power in high-RPM, high-modification applications. This cam is designed to work in Chevrolet Big Block engines originally equipped with flat tappet camshafts, and it fits a wide range of vehicles including the Chevrolet Impala, Chevelle, and C10 Pickup from the late 60s through the early 80s, as well as some later 90s C2500 Suburbans.

When installing a camshaft like this, especially in an engine that's being heavily modified, it's important to ensure all supporting components are up to the task. This includes valve springs, pushrods, and potentially the entire valvetrain. Always refer to the manufacturer's installation instructions for specific details on break-in procedures and component compatibility to get the most out of this performance camshaft.
