The COMP Cams Pontiac Extreme Energy Cam PXE268H-10 is a hydraulic flat tappet camshaft specifically designed for Pontiac V8 engines, enhancing valve lift and duration while maintaining street-friendly characteristics. This camshaft is ideal for builders seeking improved mid-range torque and higher RPM power delivery without extensive modifications.
Featuring a 0.477-inch intake lift and a 0.480-inch exhaust lift, the PXE268H-10 operates within a 268-degree intake duration and a 280-degree exhaust duration. The 110-degree lobe separation angle balances vacuum and idle quality, making it suitable for street performance applications where engine braking and part-throttle response are important.
This camshaft is particularly beneficial for those restoring or upgrading vintage Pontiac V8 engines, including the 400, 428, and 455-cubic-inch variants. It allows builders to achieve a responsive engine character without requiring significant changes to the engine's geometry, making it a versatile choice for both restoration and performance applications.
