Truck Norris Cam

The Truck Norris Cam from Brian Tooley Racing is engineered for serious truck and performance engine builders seeking maximum valve lift and duration for naturally aspirated and forced induction applications. Designed for those pushing past factory limitations, this cam profile delivers the aggressive valve timing needed to unlock additional horsepower and torque in modified truck engines. Whether you're building a street truck, competition engine, or high-performance diesel conversion, the Truck Norris Cam offers the reliability and precision that professional mechanics and enthusiasts demand.

This camshaft is precision-ground from premium billet material to exact tolerances, ensuring consistent lobe geometry and superior wear resistance across thousands of engine cycles. The aggressive lift profile and extended duration significantly improve breathing efficiency by optimizing intake and exhaust valve overlap, critical for engines running higher compression ratios or turbo/supercharger setups. Brian Tooley Racing's engineering delivers a cam grind that balances peak power output with drivability, minimizing valve train stress while maximizing scavenging efficiency. The robust construction handles the increased valve spring loads associated with performance fuel systems and modified ignition timing without compromise.

This cam suits truck owners running displacement increases, head porting, fuel injection upgrades, or forced induction modifications who require a cam grind specifically matched to those enhancements. Professional builders and experienced DIY mechanics installing the Truck Norris Cam should verify compatibility with existing valve train components, spring pressures, and pushrod geometry before final assembly. Proper valve lash adjustment and break-in procedures are essential to achieve full potential and ensure longevity. Always consult application-specific installation guides and Brian Tooley Racing technical support to confirm fitment on your specific engine platform.
