PDS Stage 3 Torque Cam

The PDS Stage 3 Torque Cam from Brian Tooley Racing is designed for serious engine builders and performance enthusiasts who want to maximize low-to-mid range torque output without compromising overall powerband versatility. This camshaft is ideal for naturally aspirated and forced-induction small-block applications, where controllable, street-friendly torque delivery is essential.

Featuring optimized lobe profiles and timing events, the PDS Stage 3 Torque Cam builds cylinder pressure early in the combustion cycle, generating significant torque across the critical 2,000–5,500 RPM range. Its design emphasizes overlap and valve lift characteristics that enhance fuel and air scavenging while maintaining stable idle quality and valve train geometry. Constructed with hardened cast-iron or billet lobes, this camshaft ensures durability under high-lift spring pressures and aggressive valve acceleration demands.

Engine builders tuning a daily driver or a weekend warrior will appreciate the predictable drivability and responsive throttle feel provided by the Stage 3 Torque profile. Proper installation requires upgraded valve springs, rocker arm geometry verification, and dyno tuning to unlock its full potential and prevent valvetrain interference.
