What kind of torque converter do I need for this camshaft?

This camshaft is designed for drag racing and requires a torque converter with a stall speed of 4500 RPM or higher to perform optimally. Using a lower stall speed converter may not allow the camshaft to reach its full potential.

Is this camshaft compatible with my stock valvetrain components?

While this camshaft is designed to be easy on parts, it's a solid roller type, which often requires specific lifters, pushrods, and valve springs that are compatible with solid roller applications. Always consult the manufacturer's detailed specifications and installation guide for recommended valvetrain components.

Can this camshaft be used in California?

No, this camshaft is not CARB approved and cannot be legally shipped to or installed in California due to emissions regulations.

Product Details

This is the COMP Cams FS 306A-R4 Solid Roller Camshaft, specifically designed for Ford 221, 255, 260, 289, and 302 small block engines. If you're building a drag racing machine and want a camshaft that's known for being easy on your engine's components while still delivering strong performance, this is a solid option. It's an automatic transmission-friendly cam, but you'll need a torque converter with a stall speed of 4500 RPM or higher to get the most out of it.

The '271/271' in its name refers to the duration at 0.050-inch lift, indicating a fairly aggressive profile that works well for drag racing applications. This camshaft is a solid roller type, which generally allows for more lift and duration compared to hydraulic flat tappet cams, leading to better airflow and power potential. COMP Cams is a well-known name in performance camshafts, and this part is built to handle the demands of racing.

Keep in mind that this camshaft is not CARB approved and cannot be shipped to California. For optimal performance and to ensure it's easy on your valvetrain, it's recommended to pair this camshaft with a high-stall torque converter. Always refer to the manufacturer's installation instructions for specific details regarding break-in procedures and component compatibility.
