COMP Cams Cam & Lifter Kit CB 314H-R10

COMP Cams is well-known for its performance camshafts and valvetrain components, and this Magnum 252/252 Hydraulic Roller Cam and Lifter Kit is a prime example of their expertise. This kit is designed for Chevrolet Big Block 396-454 engines originally equipped with flat tappet camshafts, offering a significant upgrade for street/bracket racing applications. It’s a popular choice for vehicles like the Chevrolet Impala, Chevelle, and Camaro from the late 60s through the mid-70s, as well as many truck applications like the C10 Pickup and C10 Suburban.

This kit features a hydraulic roller camshaft, which offers better performance and durability compared to traditional flat tappet designs. For optimal results, COMP Cams recommends a compression ratio of 10.5:1 or higher, a 3500+ RPM stall torque converter, and 4.10 or lower rear axle gearing. You'll also want to ensure you have good headers, an efficient intake manifold, and capable cylinder heads to take full advantage of the camshaft's aggressive profile. Expect a radical idle with this setup, indicative of its performance-oriented nature.

When you open the box, you'll find everything you need to get started: the camshaft itself, a set of lifters, assembly lube to ensure proper break-in, decals for that authentic COMP Cams look, and detailed instructions. This kit is a substantial upgrade for anyone looking to build a powerful street machine or a competitive bracket racer.
