Comp Cam 31-331-4 Magnum 253/253 Camshaft with High Performance Lifters – Radical Idle – Strong Mid-High RPM – .540/.540 Lift, 305/305 Duration – FITS Ford 260 289 302 SBF Engines

Description

This high-performance kit features the Competition Cams 31-331-4 Magnum hydraulic flat tappet camshaft paired with Enginetech high-performance hydraulic lifters, creating a powerful upgrade for Ford 221, 260, 289 and 302 small block engines. Designed for serious street/strip use, the 31-331-4 camshaft dramatically increases airflow, improves throttle response and adds an unmistakably aggressive performance idle.

The Competition Cams 31-331-4 is engineered with 305°/305° advertised duration, 253°/253° duration at .050″, .540″/.540″ lift and a 110° lobe separation angle. These specifications place this cam well above mild performance profiles and into a category designed for high-RPM strength and major airflow gains. The .540″ lift allows the valves to open significantly deeper than stock, pushing the engine into the cylinder heads’ most efficient airflow range. The extended 253° @ .050 duration keeps the valves open longer at higher lift, dramatically boosting cylinder filling, combustion efficiency and upper-RPM horsepower potential.

The 110° lobe separation angle creates substantial overlap, improving exhaust scavenging and giving the engine a deep, choppy, race-inspired idle that demands attention. This cam responds best with higher compression, upgraded cylinder heads, performance intake and exhaust, proper carburetor or EFI tuning, and a performance torque converter or deeper rear gears. When paired with the right supporting mods, the 31-331-4 delivers explosive mid-range acceleration and extremely strong top-end power.

The included Enginetech hydraulic lifters are matched to this camshaft’s lift and duration requirements, offering smooth movement, consistent oil control and the long-term durability needed for higher spring pressures and more aggressive ramp rates. With this combination, you get a fully compatible cam and lifter package designed to perform together from break-in to full-throttle use.

This kit is ideal for builders looking to transform a classic Ford small block into a more powerful, more responsive and more aggressive performance engine. If you want a camshaft that delivers serious airflow gains, harder acceleration, higher RPM power and a fierce performance idle, the Competition Cams 31-331-4 Magnum cam and Enginetech lifter kit is an outstanding upgrade.
