What kind of idle can I expect with the COMP Cams CS 304H-R10 camshaft?

This camshaft is designed for aggressive street/strip performance and will produce a very rough idle. It's best suited for applications where idle quality is not the primary concern.

What supporting modifications are recommended for this camshaft?

For optimal performance, it is recommended to use a 3000+ RPM stall torque converter, 4.10 gears, an aftermarket intake manifold, and headers. These components help the engine breathe and utilize the camshaft's aggressive profile.

Does this camshaft come with lifters or other valvetrain components?

This product is for the camshaft only. It is designed to work with factory roller lifters in compatible engines. Other valvetrain components like valve springs and retainers may need to be upgraded separately to match the camshaft's specifications.

Product Details

If you're building a street/strip Small Block Chevy and want a noticeable bump in performance, this COMP Cams CS 304H-R10 hydraulic roller camshaft is a solid option. It's designed for engines from 1987 and newer with factory roller camshafts, covering a wide range of Chevrolet and Buick vehicles like the Camaro, Corvette, Caprice, and Roadmaster. This camshaft is intended for applications where you're running a 3000+ RPM stall torque converter, 4.10 gears, and aftermarket intake and headers, aiming for a significant increase in powerband. Expect a very rough idle with this aggressive profile.

The CS 304H-R10 features a 244 degrees of intake and exhaust duration at .050 lift, which is a substantial amount of time the valves stay open. This duration, combined with its hydraulic roller design, allows for better airflow and higher RPM capability compared to flat tappet cams. The hydraulic roller setup also reduces friction and wear on the camshaft lobes and lifters, contributing to a more durable valvetrain. COMP Cams is well-known for producing reliable performance camshafts, and this one is built to handle the demands of spirited driving and occasional track use.

To get the most out of this camshaft, it's recommended to pair it with an aftermarket intake manifold and headers to help the engine breathe more freely. The aggressive nature of this cam means it will have a rough idle, so it's best suited for vehicles where that characteristic is acceptable. Ensure your engine has the necessary supporting modifications, such as the recommended stall converter and gear ratio, to take full advantage of the performance gains this camshaft offers.
