TSP PDS LT Stroker Cam – 3-Bolt

The Texas Speed & Performance PDS LT Stroker Cam – 3-Bolt is designed for high-displacement LT-based engines paired with positive displacement superchargers like Whipple, Magnuson, or LT4 setups. With its aggressive profile, wide lobe separation, and high fuel lobe, this camshaft is optimized for torque, drivability, and boost efficiency. Built to deliver serious power in stroked, boosted LT builds using a 3-bolt cam gear conversion.
