COMP Cams Camshaft Kit CB XR274 R-10

If you're looking to build a strong, reliable power plant for your Chevrolet Big Block engine, this COMP Cams Xtreme Energy XR274 R-10 Solid Roller Cam Kit is a solid option. This kit is designed for power touring applications and is known for delivering dependable power while being relatively easy on your engine's components. It's a popular choice for enthusiasts looking for an improved performance feel without going overboard on complexity.

This comprehensive kit includes everything you need to get your camshaft upgrade done right. You'll find the XR274 R-10 solid roller camshaft itself, along with a full set of lifters, valve springs, retainers, and valve locks. It also comes with valve stem seals, a timing chain set, and assembly lube, ensuring you have the necessary parts for a proper installation. COMP Cams even includes decals and instructions to guide you through the process. This kit is intended for Chevrolet Big Block 396-454 engines that originally came with flat tappet camshafts, and it requires a torque converter with at least a 2500 RPM stall speed to perform optimally.

While this kit is built for performance and reliability, it's important to note that it produces a rough idle, which is typical for solid roller camshafts of this nature. It's a trade-off for the significant power gains and the easy-on-parts reliability it offers. This kit is compatible with a wide range of Chevrolet vehicles from the late 1960s through the mid-1980s, including popular models like the Chevrolet Impala, Chevelle, and C10 Pickup, among many others originally equipped with these Big Block engines.
