COMP Cams Cam & Lifter Kit CS 270H-R10

This COMP Cams Magnum hydraulic roller camshaft and lifter kit is built around a 215/215 duration profile, meaning it's designed for mild street performance. You'll get a slightly noticeable lope at idle, which is a classic sound for a street-oriented performance cam. It's intended to work well with a stock torque converter and aftermarket intake and headers, making it a solid choice for builds aiming for a bit more power without needing extensive modifications or a full drivetrain overhaul. The kit is engineered for Chevrolet Gen 1 Small Block engines, covering a wide range of displacements from 262 up to 400 cubic inches.

Inside this kit, you'll find the camshaft itself, a set of hydraulic roller lifters, assembly lube to ensure proper break-in, and decals for your engine bay. The hydraulic roller design means less friction and wear compared to flat tappet cams, and it allows for more aggressive lobe profiles, contributing to improved performance and reliability over time. This kit is a popular choice for those looking to upgrade their engine's breathing characteristics for better throttle response and a modest power increase, especially when paired with appropriate rear gear ratios like 3.40 to 4.10.

It's important to verify your specific Chevrolet Small Block is a flat tappet block before installation, as this kit is not compatible with factory roller blocks from 1985 and newer, or LT1/LT4 engines. Many trucks and SUVs retained flat tappet cams well into the mid-90s, so checking the intake manifold or timing cover is the best way to confirm. For 1955-1957 Chevrolet 265 engines, a specific oiling groove on the 5th cam journal is required; contact COMP Cams for details if your engine falls into this category.
