What kind of idle can I expect with this camshaft?

This camshaft is designed to provide a slightly noticeable idle. It balances performance gains with a streetable idle characteristic, making it suitable for highway cruiser applications.

What compression ratio and torque converter are recommended for this camshaft?

This camshaft performs best in engines with a static compression ratio of 9.5:1 or higher. It also works well with aftermarket torque converters that have a higher stall speed.

Is this camshaft compatible with stock valve train components?

Product Details

If you're looking to get more out of your Ford Small Block engine, especially for a highway cruiser build, this COMP Cams Magnum series camshaft is a solid choice. It's designed to offer a noticeable performance increase over stock without being overly aggressive on your valve train components. This camshaft is particularly well-suited for engines with a static compression ratio of 9.5:1 or higher, and it really shines when paired with an aftermarket torque converter that has a higher stall speed.

The Magnum grind family is known for delivering strong high-RPM power. While it will give you a slightly noticeable idle, it's engineered to avoid unnecessary wear on your valve train parts. This makes it a great option for performance engines that are already set up with mild ratio rocker arms and traditional performance valve springs. It's a well-built component that balances improved performance with reasonable wear characteristics.

This camshaft is intended for Ford 221, 255, 260, 289, and 302 Small Block engines. Please note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and compatibility details.
