What kind of idle sound can I expect with this camshaft?

This camshaft is designed for a radical race idle. You should expect a very noticeable, aggressive idle sound that is characteristic of high-performance street or race engines.

What compression ratio is recommended for this camshaft?

To achieve optimal performance and power from this camshaft, a compression ratio of at least 11:1 is recommended. This helps ensure efficient combustion with the aggressive cam profile.

What are the key differences between a solid roller and a hydraulic roller camshaft?

Solid roller camshafts use a solid lifter and roller assembly, which allows for more aggressive lobe profiles and higher RPM potential due to reduced friction. Hydraulic roller cams use a hydraulic lifter, which self-adjusts valve lash and typically offers a quieter, smoother operation.

Product Details

This COMP Cams FC 308R-10 camshaft is a solid roller design, meaning it uses roller lifters to reduce friction and allow for more aggressive lobe profiles. It's built for Ford 351 Cleveland, 351 Modified, and 400 Modified engines, and is intended for serious pro-street applications where a radical race idle is acceptable. This camshaft is designed to work best with a 4000+ RPM stall torque converter or a four-speed manual transmission, and requires at least 11:1 compression to achieve its full potential.

The Magnum 262/262 lobe separation and duration figures indicate a cam that will generate significant power in the upper RPM range. This isn't a cam for a daily driver; it's for a vehicle built for performance on the street or strip. You can expect a very noticeable, aggressive idle sound. Because it's a solid roller, proper valve spring selection and regular oil changes are crucial for longevity.

This camshaft fits a wide range of Ford and Mercury vehicles from the late 60s through the mid-80s, including popular models like the Ford Mustang, Ford F-150, and Mercury Cougar. Ensure your engine's rotating assembly can handle the demands of a high-performance solid roller camshaft, and always follow the manufacturer's recommended break-in procedure to ensure proper seating of the lobes.
