What is required to install this camshaft?

This camshaft requires an engine computer re-tune (programmer) to function correctly and achieve its performance potential. It's also recommended to inspect and potentially replace valvetrain components such as valve springs, lifters, and pushrods during installation.

What kind of performance gains can I expect?

This camshaft is designed to improve power in the mid-range and high RPM bands, making it suitable for street/strip use. The specific gains will depend on your engine's existing setup and the quality of the tune.

Does this camshaft fit engines with VVT or AFM?

No, this camshaft is specifically designed for GM LS-based engines that do not have Variable Valve Timing (VVT) or Active Fuel Management (AFM) systems.

Product Details

This is the COMP Cams XFI 222/234 hydraulic roller camshaft, designed for GM LS2 and LS3 engines that do not have Variable Valve Timing (VVT) or Active Fuel Management (AFM). It's a well-built camshaft that focuses on bringing out more power in the mid-range and at higher RPMs, making it a popular choice for street/strip applications where you're looking for improved performance beyond stock.

The XFI series uses advanced lobe designs to achieve a good balance between performance and drivability. This particular grind, the 222/234, refers to the intake and exhaust duration at 0.050 inches of lift, which gives you a solid indication of its performance characteristics. Because this camshaft changes the engine's breathing significantly, you'll need to have the engine's computer reprogrammed (tuned) to take full advantage of its capabilities and ensure everything runs smoothly. This is a common requirement for any significant camshaft upgrade.

This camshaft fits a wide range of GM vehicles, including popular models like the Chevrolet Camaro, Cadillac CTS, and Pontiac G8. When installing a camshaft, it's always a good idea to inspect and potentially replace other valvetrain components like valve springs, lifters, and pushrods to ensure optimal performance and longevity. Always refer to the manufacturer's installation instructions for specific details and recommended supporting modifications.
