Pontiac Extreme Energy Cam PXE262H-10

The Pontiac Extreme Energy Cam PXE262H-10 from COMP CAMS is a high-performance hydraulic roller camshaft engineered for Pontiac V8 engines seeking aggressive street and strip performance. This cam is built for enthusiasts and tuners who demand increased valve lift, extended duration, and optimized overlap to unlock horsepower and torque across the powerband. Whether you're building a resto-mod, upgrading a classic Pontiac muscle car, or maximizing output on a modern LS-based application, the Extreme Energy series delivers the mechanical advantage serious builders expect.

Designed with a hydraulic roller lifter profile, the Pontiac Extreme Energy Cam features precision-ground lobes that reduce friction and wear while maintaining valve control across the rpm range. The cam's profile geometry—indicated by the PXE262H designation—provides elevated lift and duration specifications that improve cylinder filling and scavenging, critical factors in maximizing combustion efficiency and peak power output. COMP CAMS' manufacturing tolerances ensure consistent lobe geometry and hardened surfaces that resist wear, while the roller design minimizes parasitic drag on the engine block, translating to measurable power gains and improved reliability under demanding conditions.

This camshaft is ideal for Pontiac V8 engines equipped with stock or upgraded hydraulic roller lifter systems and compatible valve train components. Installation requires proper valve lash adjustment, timing verification, and verification of valve-to-piston clearance—critical steps that demand mechanical experience or professional guidance. Builders integrating the Pontiac Extreme Energy Cam should confirm compatibility with their existing intake manifold, cylinder head, and fuel management system, as aggressive cam profiles may require supporting modifications to intake flow, exhaust scavenging, and tuning parameters to realize full performance potential and maintain street driveability.
