5.7 Hemi Truck Norris Cam w/VVT

The 5.7 Hemi Truck Norris Cam with VVT from Brian Tooley Racing is engineered for serious truck builders and performance enthusiasts seeking to unlock additional horsepower and torque from their 5.7-liter Hemi platform. This camshaft is specifically designed for trucks running stock or mildly modified Hemi engines where maximizing low-to-mid-range power delivery is critical. Whether you're building a daily-driven performance truck or a weekend warrior, the Norris grind delivers the aggressive valve timing needed to transform your engine's breathing characteristics without requiring extensive supporting modifications.

This cam features VVT (Variable Valve Timing) compatibility, which means it works seamlessly with your truck's factory electronic VVT system for superior drivability across the entire RPM range. The Norris grind utilizes optimized lobe profiles to increase intake and exhaust valve lift while extending duration, promoting better cylinder filling and scavenging. Brian Tooley Racing's proprietary lobe geometry reduces valve spring pressure requirements compared to aggressive solid lifter designs, protecting your factory valvetrain components while delivering noticeable seat-to-seat improvements. The cam's precision-ground lobes and quality steel construction ensure reliability and consistent performance over thousands of miles.

This camshaft is ideal for truck owners running 5.7 Hemi engines with factory VVT systems—particularly RAM 1500, RAM 2500, and Dodge truck applications. Installation requires camshaft replacement during top-end work and is straightforward for experienced builders using standard Hemi timing procedures. The Norris Cam pairs excellently with mild bolt-on upgrades like intake manifolds, fuel system enhancements, and quality exhaust systems for cumulative gains. Verify your specific Hemi engine year and VVT configuration before purchase to ensure compatibility with your truck's valvetrain setup.
