What is the primary benefit of the XE256H-10 camshaft?

The main advantage of this camshaft is its strong torque output in the low and mid-range RPMs. It's designed to make your engine feel more responsive when accelerating from a stop or cruising, while still providing a good idle.

Does this camshaft come with all the necessary parts for installation?

This product listing is for the camshaft itself. It's important to note that flat tappet camshafts require specific break-in procedures and often benefit from new lifters, valve springs, and pushrods for optimal performance and longevity. Please consult the manufacturer's installation instructions for a complete list of recommended components.

What is the difference between the 'Old' and 'Windsor' firing orders mentioned?

The 'Old' firing order refers to an earlier design for Ford Small Block engines, while the 'Windsor' firing order is the standard for the 351 Windsor. This camshaft is designed to work with either of these specific firing orders, ensuring proper engine operation.

Product Details

This COMP Cams Xtreme Energy camshaft is designed for Ford 351 Windsor engines, specifically those with the "Old" firing order or the "Windsor" firing order. It's a hydraulic flat tappet camshaft that aims to give you a noticeable boost in torque right from the low end of your RPM range and through the mid-range, while still maintaining a smooth idle. This makes it a solid choice for street-driven vehicles where you want improved responsiveness without sacrificing everyday drivability.

The XE256H-10 features a 212 degrees of intake duration and 218 degrees of exhaust duration, with a .050 inch lift of .212" intake and .218" exhaust. This particular grind is well-known for its ability to pull strong from lower RPMs, making it feel more potent when you're accelerating from a stop or cruising at lower speeds. It's built with COMP Cams' Xtreme Energy technology, which is their approach to creating camshafts that offer improved performance characteristics.

When installing this camshaft, remember that it's a flat tappet design, which requires careful attention to lubrication during break-in to ensure the tappets and cam lobes wear in properly. It's a popular upgrade for a wide range of Ford vehicles, including trucks like the F-150 and Broncos from the 80s and 90s, offering a tangible improvement in low-to-mid range power.
