What is a solid roller camshaft and why would I choose one?

A solid roller camshaft uses roller bearings on the lifters to reduce friction compared to flat tappet designs. This allows for more aggressive cam profiles, higher lift, and better performance at high RPMs, making it ideal for performance-oriented engines.

What other components are typically needed when installing this camshaft kit?

For a camshaft of this performance level, you'll likely need a higher stall torque converter, appropriate rear axle gearing (4.10 or lower), and potentially upgraded valve springs and pushrods to match the camshaft's specifications. Always refer to the manufacturer's instructions for complete details.

Does this kit include everything needed for installation?

This kit includes the camshaft, lifters, assembly lube, and decals. While it provides the core valvetrain components, you may need additional items such as gaskets, timing set, and potentially upgraded hardware depending on your specific engine build.

Product Details

If you're building a Pro Street Ford with a 221, 255, 260, 289, or 302 small block engine, this COMP Cams FS 308-R10 solid roller camshaft and lifter kit is designed to give you that radical idle and serious performance you're after. This kit is intended for builds that will see 3500+ RPM and are paired with 4.10 or lower rear-end gears, making it a serious upgrade for street-driven machines that demand attention.

This kit includes the camshaft, a full set of lifters, assembly lube to ensure proper break-in, and decals to show off your new performance parts. The solid roller design means you're getting a high-performance valvetrain that can handle aggressive lift profiles and high engine speeds, contributing to improved airflow and power output. It's a well-built package that COMP Cams is known for, aiming to provide a solid foundation for your engine's top end.

When installing this kit, remember that a camshaft this aggressive typically requires a higher stall torque converter and appropriate gearing to perform at its best. It's a significant change from stock, so ensure your entire drivetrain is ready to handle the increased power and RPM range. This kit fits a wide range of Ford vehicles, including models like the Mustang, F-150, and Bronco from various years.
