Product Details

COMP Cams is well-known for performance engine components, and this Xtreme Energy CS XR280R-10 solid roller camshaft kit is a prime example of their expertise. This kit is designed for street machines that demand more power, specifically those running 10:1 or higher compression ratios, 3.73-3.90 rear gears, and a 2800+ RPM stall torque converter. It's built for Chevrolet GEN 1 Small Block engines, covering a wide range of displacements from 262ci up to 400ci, including popular engines like the 350 and 327. This kit is a comprehensive package to get your engine breathing better and making more power.

Inside this kit, you'll find the Xtreme Energy 242/248 solid roller camshaft itself, along with a set of lifters, a complete timing chain set, assembly lube to ensure proper break-in, and decals. The camshaft features a 242-degree intake and 248-degree exhaust duration at .050-inch lift, making it a potent choice for maximizing performance in your street machine. It's important to note that this kit is designed for blocks with a flat tappet camshaft setup. If your engine was built from 1985 or later, it's crucial to remove the intake manifold or timing cover to confirm whether your block is a factory roller or flat tappet design, as this kit will not fit factory roller blocks. Early 1955-1957 Chevrolet 265 engines may also require a specific oiling groove on the 5th cam journal.

This kit is a significant upgrade for enthusiasts looking to extract maximum performance from their classic Chevrolet V8. While it fits a broad spectrum of GEN 1 Small Blocks, including those found in vehicles like the Chevrolet C10, Camaro, and Corvette from various years, always verify your specific engine block's configuration before installation. This is not a CARB-approved part and cannot be shipped to California.
