Product Details

This COMP Cams CB 285C-R8 camshaft is a solid roller type, specifically designed for Chevrolet Big Block engines ranging from 396 to 454 cubic inches. It's built for demanding applications like jet boats with A impellers, flat bottom hulls, and river racing, where consistent performance under stress is key. This camshaft is intended as a replacement for engines originally equipped with flat tappet camshafts, offering an upgrade path for those seeking improved performance.

The camshaft features a 252-degree intake duration and a 262-degree exhaust duration at .050 inch lift, with a .630 inch intake lift and .630 inch exhaust lift. These specifications are tailored for high-RPM power bands common in marine and racing environments. The solid roller design means it uses roller lifters, which reduce friction compared to flat tappet designs, allowing for more aggressive cam profiles and better valve train stability at high speeds. This camshaft fits a wide range of Chevrolet vehicles, including popular models like the 1967-1975 Chevrolet Bel Air, 1967-1972 Chevrolet Biscayne, and 1973-1974 Chevrolet Blazer, among many others.

When installing this camshaft, remember that it is designed for specific engine configurations and intended uses. It's important to ensure your engine's valve train components, such as lifters, pushrods, and valve springs, are compatible with a solid roller camshaft and the lift and duration specifications of this particular grind. Proper installation and component matching are crucial for achieving the performance benefits and ensuring the longevity of your engine.
