Ever since its introduction, GM's Gen III (LS1,-2,-6) engine has quickly become the ''preferred choice'' among many engine builders and performance enthusiasts. Right from the factory, the GM Gen III engine boasts a surprisingly efficient induction design, reduced weight and impressive power output. As the leading developer of high performance Gen III valve train technology, COMP Cams has engineered a full line of products proven to release the incredible horsepower and torque hidden inside while never sacrificing ever-critical reliability. Regardless of the application, COMP Cams has the GM Gen III engine products that deliver the performance you demand.

In their never-ending quest to raise the bar of street-able performance, the design engineers at COMP Cams have added three brand-new solid roller profiles to their already impressive lineup of Gen III-specific cams. Engineered specifically to take advantage of the phenomenal efficiency of the FAST LSX Intake Manifold, the newest members of the XFI line of Gen III camshafts deliver some of the most aggressive lobe profiles that have ever been designed for street driven Gen III-powered vehicles - resulting in massive increases in horsepower output, throttle response and upper rpm capability over the factory hydraulic roller patterns.

The XFI Street Solid Roller Series features 3 camshaft patterns for applications ranging from high performance street to high rpm drag/road race. These patterns are designed specifically to be run in 1997 to current LS1, LS2 and LS6-based engines with the new COMP Cams Endure-X Gen III Solid Roller Lifters and Part #26921 Dual Valve Springs. The LSX Intake Manifold is recommended for best performance with all patterns.
