COMP Cams Cam & Lifter Kit CB XR280 R10

If you're building a street machine that needs a serious bump in performance, this COMP Cams Cam and Lifter Kit is designed to get you there. This kit features the XR280 R10 solid roller camshaft and matching lifters, specifically tuned for Chevrolet Big Block engines like the 396, 427, and 454 cubic inch V8s. It's built for applications that already have a healthy stall speed torque converter, around 2800 RPM or higher, and are running a compression ratio of 10:1 or more, paired with rear gears in the 3.73 to 3.90 range. This combination is what it takes to really make this cam shine.

This isn't just a camshaft; it's a complete system. You get the solid roller camshaft, the necessary lifters designed to work with it, assembly lube to ensure a smooth break-in, and even some decals to show off your performance parts. Solid roller setups like this offer a significant advantage in terms of reduced friction and the ability to achieve higher RPMs compared to traditional flat tappet designs. This translates to more power and a more aggressive engine character, making it a popular choice for hot rods and muscle cars looking for that extra edge.

When installing a solid roller camshaft, it's crucial to follow the included instructions carefully, especially regarding the break-in procedure for the lifters. This kit is intended for Chevrolet Big Block engines originally equipped with flat tappet camshafts, and it's a substantial upgrade for those seeking to push their engine's capabilities. Remember, this kit is not CARB approved and cannot be shipped to California.
