The COMP CAMS Pontiac V8 Xtreme Hydraulic Roller Cam XR276HR-10 is a high-performance camshaft designed specifically for naturally aspirated Pontiac V8 engines. It aims to enhance mid-range and peak horsepower while maintaining street-friendly idle characteristics. This camshaft is ideal for muscle car restorations, street rod builds, and performance upgrades.
Engineered with Xtreme Energy technology, the XR276HR-10 features a hydraulic roller design that maximizes valve lift and duration. With an intake lift of 0.502 inches and an exhaust lift of 0.510 inches, this camshaft opens and closes the valves more aggressively than stock profiles. The 276-degree intake and 282-degree exhaust duration at 0.050-inch valve lift optimize power production across a broad RPM range.
This camshaft is compatible with Pontiac V8 engines equipped with hydraulic roller lifters, ensuring reliable performance in both street and strip applications. It functions seamlessly with factory and aftermarket aluminum heads and iron blocks, making it a versatile choice for performance enthusiasts. The precision-ground, induction-hardened profile guarantees consistent lobe geometry and extended longevity.
