What is the recommended break-in procedure for this camshaft?

Proper break-in is crucial for hydraulic flat tappet camshafts. You must follow the manufacturer's specific procedure, which typically involves running the engine at 2000-2500 RPM for about 20 minutes immediately after installation to properly seat the lifters.

Does this camshaft require special valve springs or lifters?

This is a hydraulic flat tappet camshaft, so it uses hydraulic flat tappet lifters. While it's designed to work with stock-style valvetrain components, it's always recommended to check the manufacturer's specifications for compatible valve springs to ensure optimal performance and longevity.

Can this camshaft be shipped to California?

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

Product Details

This COMP Cams Xtreme Energy camshaft, part number 31-234-3, features a 212-degree intake and 218-degree exhaust duration with a .050 lift of 224 degrees. It's a hydraulic flat tappet design intended for Ford 221 through 302 cubic inch small block V8 engines. This camshaft is well-suited for builds aiming for improved torque in the low and mid-range RPM bands, while still maintaining a manageable idle quality.

The XE256H-10 is a popular choice for a wide range of Ford vehicles, including models like the Bronco, F-150, and Fairlane from the 1960s and 70s, as well as later models up to the early 90s. Its design focuses on creating a strong pull from off-idle up through the mid-range, making it a solid option for street-driven vehicles where low-end grunt is more important than peak horsepower. The hydraulic lifters mean it doesn't require the same level of adjustment as a solid lifter cam, simplifying maintenance.

When installing this camshaft, remember that it is designed for flat tappet applications. Ensure your engine's valvetrain components are compatible and that you follow the manufacturer's break-in procedure carefully to properly seat the lifters and prevent premature wear. This camshaft is not CARB approved and cannot be shipped to California.
