Pontiac Extreme Energy Cam PXE274H-10

The Pontiac Extreme Energy Cam PXE274H-10 by COMP CAMS is a performance-focused hydraulic roller camshaft engineered for street and light performance applications on Pontiac V8 engines. This cam is designed for enthusiasts who want to unlock additional horsepower and torque without requiring extensive engine modifications or exotic fuel requirements. Whether you're restoring a classic Pontiac or upgrading an existing build, this camshaft delivers the aggressive lift and duration profile necessary to transform your engine's breathing characteristics and overall responsiveness.

Built with COMP CAMS' proven hydraulic roller design, the Pontiac Extreme Energy Cam PXE274H-10 features precision-ground lobes and premium-quality steel construction that withstands sustained high-RPM operation. The PXE series profile balances aggressive valve overlap with stable idle characteristics, making it street-friendly while still delivering meaningful power gains across the mid to upper RPM range. The hydraulic roller design minimizes friction losses compared to solid lifter designs, improving mechanical efficiency and reducing parasitic drag on the crankshaft. This engineering translates to better fuel economy during cruise and more aggressive pull during acceleration.

This cam is ideal for Pontiac V8 engine platforms utilizing stock or modified hydraulic roller lifter configurations, making installation straightforward for most builds. Mechanics and weekend warriors benefit from the bolt-in compatibility with existing Pontiac engine blocks and timing components—no special clearancing or custom fabrication required. Paired with a quality intake manifold, carburetor or fuel-injection tuning, and a properly jetted or tuned ignition system, the Pontiac Extreme Energy Cam PXE274H-10 delivers noticeable improvements in throttle response and overall engine character. Weighting 9.38 lbs, this cam is a direct replacement for stock Pontiac camshafts, making core swap or fresh builds equally straightforward.
