Ford 302 Nitrous HP Cam- HYR NX 274HR14

The Ford 302 Nitrous HP Cam - HYR NX 274HR14 by COMP CAMS is a specialized camshaft engineered for small-block Ford engines running nitrous oxide systems. This cam is purpose-built for enthusiasts and serious mechanics who demand reliable power delivery under the extreme cylinder pressures and rapid combustion cycles that nitrous augmentation creates. Unlike general-purpose performance cams, this nitrous-optimized profile ensures consistent valve timing, aggressive lift, and dwell characteristics that maximize horsepower while maintaining engine stability during chemical boost events.

The 274HR14 designation indicates a mid-to-aggressive lift and duration profile specifically calibrated for nitrous applications, where rapid fuel combustion demands precise valve overlap and quick exhaust scavenging. COMP CAMS' engineering addresses the unique demands of nitrous systems: tighter tolerances, optimized lobe geometry, and increased durability to handle repeated high-pressure spikes without premature valve float or lobe wear. The cam's solid lifter design and high-lift profile ensure maximum port flow during the critical intake and exhaust strokes, translating nitrous charge into measurable horsepower gains while resisting the stress that liquid nitrogen injection imposes on mechanical components.

This camshaft is ideal for 302 cubic-inch Ford engines—the legendary small-block platform used in Mustangs, Fairlanes, and custom hot rods—particularly in builds where N₂O systems ranging from 75 to 150+ horsepower are planned. Installation requires proper valve spring selection, lifter compatibility checks, and accurate valve lash or preload adjustment to ensure reliability. Mechanics should verify existing engine internals (rockers, pushrods, timing chain) are compatible with the aggressive lift profile before installation. This cam pairs best with intake and exhaust manifolds optimized for flow, fuel system upgrades, and properly tuned nitrous controllers to extract full potential without sacrificing durability or drivability.
