COMP Cams Camshaft GM Gen V LT1 Ltav 27

If you're looking to get more power out of your GM Gen V LT1 engine, this XFI AFM camshaft from COMP Cams is a solid option. It's designed to work with the factory direct injection, Variable Valve Timing (VVT), and Active Fuel Management (AFM) systems found in these engines, meaning you can leverage the OE technology for performance gains. This camshaft is compatible with a wide range of vehicles, including models like the Chevrolet Camaro, Corvette, and Silverado, as well as GMC Sierra and Yukon, and Cadillac Escalade.

This camshaft features four different lobe profiles, specifically engineered to maintain AFM compatibility while optimizing intake and exhaust valve events. The result is an increase in torque and horsepower across the entire RPM range, offering noticeable improvements in responsiveness and mid-range power compared to stock. For modified LT1 applications with AFM, this cam provides outstanding top-end power, with only slight low-end losses if the PCM is properly tuned. To ensure proper operation and to limit the camshaft's movement range, you'll need to install the COMP Phaser Limiter Kit (Part #5456) and have the PCM tuned.

This camshaft is suitable for stock to highly modified applications. Remember that this part is not CARB approved and cannot be shipped to California. For optimal performance and to ensure the camshaft functions correctly within the VVT system, a PCM tune is essential after installation.
