COMP Cams Camshaft Kit CB XE284H-10

COMP Cams is well-known for performance engine components, and their Xtreme Energy line is designed for enthusiasts looking for a noticeable bump in power. This K-Kit, part number K11-250-3, is a complete camshaft and valvetrain package specifically for Chevrolet Big Block engines originally equipped with flat tappet camshafts, like the 396, 427, and 454 cubic inch V8s. If you're building a street/strip machine that needs more grunt and you're aiming for a 2800+ RPM stall speed, this camshaft kit is a solid option.

This kit includes everything you need to swap out your old camshaft and valvetrain for an improved setup. You get the XE284H camshaft itself, which has a 240/246 degree duration at .050 lift, along with hydraulic flat tappet lifters, valve springs, retainers, valve locks, and valve stem seals. To ensure a proper installation, it also comes with a timing chain set and assembly lube. This comprehensive package helps ensure that all the components are matched for optimal performance and reliability. The kit is designed for engines with a 9.5:1 or higher compression ratio and will result in a rough idle, which is characteristic of aggressive camshaft profiles like this one.

This kit fits a wide range of Chevrolet vehicles originally equipped with these Big Block engines, including models like the Chevrolet C10 Pickup, Chevrolet Impala, and Chevrolet Camaro from the late 60s through the mid-70s. It's important to note that this camshaft kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's instructions for detailed installation procedures and any specific requirements for your application.
