Pontiac V8 Hi-Energy Hyd Cam - 252H10

The COMP CAMS Pontiac V8 Hi-Energy Hydraulic Flat Tappet Camshaft (model 252H10) is a high-performance cam engineered for small-block and mid-block Pontiac V8 engines seeking reliable power gains without sacrificing streetability. This hydraulic flat-tappet design delivers 0.425 inches of lift on both intake and exhaust, paired with a 252-degree duration specification and 110-degree lobe separation angle, making it a proven choice for muscle car restoration and performance upgrades.

The 252H10 specification balances aggressive cam timing with hydraulic actuation, which uses engine oil pressure to automatically adjust valve clearance and reduce mechanical complexity compared to solid-tappet designs. The 800 to 4800 RPM operating range positions this cam as a mid-range performer—optimal for street-driven Pontiacs and weekend track cars where low-end torque and mid-range responsiveness matter more than peak RPM horsepower. The Hi-Energy profile is COMP CAMS' designation for elevated lift and duration relative to OEM Pontiac specifications, meaning noticeable power delivery gains across the powerband without extreme valve events that demand premium fuel or radical engine tuning.

This camshaft suits Pontiac V8 owners restoring original muscle cars, upgrading tired stock engines, or building budget-conscious performance combinations where hydraulic actuation simplifies lifter replacement and reduces valve train noise. Pontiac V8 camshaft selection is application-specific, so verify your engine block code and intake manifold compatibility before purchase. The 252H10 pairs well with stock or mildly modified intake and exhaust systems and does not typically require transmission or gear ratio changes for street operation.
