What is the main difference between this camshaft and a factory camshaft?

This COMP Cams CS 280H-10 camshaft has more aggressive timing and duration (224/224 at .050 lift) compared to a stock camshaft. This allows for better airflow and increased power, especially at higher RPMs, but results in a rougher idle.

How do I know if my engine has a flat tappet or roller camshaft?

You will need to remove the intake manifold or timing cover to visually inspect the camshaft and lifters. Factory roller camshafts have a different design for the lifters and camshaft lobes. Many engines from 1985 onward switched to roller cams, though some trucks retained flat tappets longer.

What other parts are recommended when installing this camshaft?

For optimal performance, it's recommended to use a torque converter with a 2500+ RPM stall speed, headers, and appropriate rear-end gearing. You may also need new lifters and valve springs if they are not being reused from a previous performance build.

Product Details

COMP Cams is a well-known name in performance engine components, and this CS 280H-10 camshaft is built for enthusiasts looking to get more out of their Small Block Chevrolet engine. This is a hydraulic flat tappet camshaft designed for engines from 1958 through 1998, covering a wide range of popular displacements like the 350, 400, and smaller 262 to 327 cubic inch variants. It's a solid choice for street machines that demand a noticeable bump in performance.

The CS 280H-10 features a 224-degree intake and 224-degree exhaust duration at .050 lift, giving it a rough idle that signals its performance intent. To make the most of this camshaft, you'll want to pair it with a torque converter that has a 2500+ RPM stall speed, along with headers and appropriate rear-end gearing. This setup ensures the engine can effectively utilize the improved airflow and valve timing this camshaft provides, especially at higher RPMs.

It's important to note that this camshaft is intended for engines with a factory flat tappet valvetrain. Many later model Small Block Chevys, particularly from 1985 onward, came equipped with roller camshafts from the factory. You'll need to confirm your specific engine's configuration by removing the intake or timing cover to ensure compatibility. This camshaft fits a wide variety of vehicles, including many Chevrolet C/K trucks, Camaros, and Caprices from the specified years.
