COMP Cams Camshaft GM LS1 & LS6 XFI 278

This is the COMP Cams XFI 278 camshaft, part number 54-501-11, designed for GM LS-based engines. It’s built to give you a noticeable boost in mid and upper RPM power, making it a popular choice for street/strip applications where you want more performance when you get on the throttle. This camshaft fits a wide range of GM vehicles, including models like the Chevrolet Camaro, Corvette, and Silverado, as well as Cadillac CTS and Escalade, and Buick LaCrosse, among many others with 4.8L to 7.0L LS engines.

The XFI 278 camshaft features a specific grind profile that focuses on delivering strong performance in the mid-range and top end of the RPM band. To get the most out of this camshaft and ensure proper operation, you'll need to make a few supporting modifications. COMP Cams recommends an intake upgrade to help the engine breathe better, and you'll also need to upgrade your valve springs to handle the increased lift and duration. A programmer is also required to properly tune the engine management system for the new camshaft profile.

When installing this camshaft, it's important to follow the manufacturer's instructions closely. Because this is a performance camshaft, it's designed for a more aggressive driving style. While it’s not CARB approved and cannot be shipped to California, it offers a significant improvement for enthusiasts looking to extract more power from their LS engine. Make sure you have the necessary tools and knowledge for installation, or consider having a professional mechanic handle the job to ensure optimal performance and reliability.
