COMP Cams Camshaft Kit CB 304H-R10

When you're looking to get serious about performance for your Chevrolet Big Block engine, this K-Kit from COMP Cams is a comprehensive package. What you get in this box is everything needed to swap out your old camshaft setup for a much more aggressive hydraulic roller system. Inside, you'll find the CB 304H-R10 camshaft itself, a set of lifters, valve springs, retainers, valve locks, and valve stem seals. It also includes a timing chain set to ensure proper synchronization, assembly lube for flat tappet applications, and even some decals and instructions to guide you through the process.

This particular camshaft, the CB 304H-R10, is built for street/strip applications and is designed to work with engines requiring 10:1 or higher compression ratios. For best results, COMP Cams recommends pairing it with a torque converter rated for 3000+ RPM stall speed, 4.10 or numerically higher rear end gears, and aftermarket intake and headers. Expect a very rough idle with this setup, which is characteristic of high-performance cams that prioritize top-end power. This kit is a solid option for those looking to significantly change the powerband and sound of their 396 to 454 cubic inch Chevrolet Big Block.

This kit is designed to fit a wide range of Chevrolet Big Block engines originally equipped with flat tappet camshafts, covering many popular models from the late 60s through the mid-80s, including vehicles like the Chevrolet Impala, Chevelle, and C10 Pickup. It's important to note that this part is not CARB approved and cannot be shipped to California.
