Description
Description
This complete performance valvetrain package includes the Competition Cams 31-331-4 Magnum hydraulic flat tappet camshaft, Enginetech high-performance hydraulic lifters, a true double roller timing set, Stage 2 dual valve springs with retainers and a set of 6.876-inch push rods. Designed for 1969–1991 non-roller Ford 302 engines, this kit provides dramatic performance gains, stronger acceleration, louder and more aggressive idle tone and significantly improved upper-RPM horsepower.
The Competition Cams 31-331-4 camshaft features 305° advertised duration, 253° duration at .050, .540″/.540″ lift and a tight 110° lobe separation angle. These specifications place this grind in the serious street/strip range. The .540″ lift opens the valves deep into the most efficient airflow zone of the cylinder heads, maximizing breathing capability. The long duration at .050 keeps the valves open longer at higher lift, increasing cylinder filling and combustion efficiency at elevated RPM. The tight 110° LSA increases overlap, improving scavenging and producing a loud, rough performance idle that clearly signals a high-output engine.
The included double roller timing set stabilizes valve events by minimizing chain stretch and maintaining precise cam timing. The Stage 2 valve springs and retainers deliver the strength required to control the valvetrain at higher lift and RPM. The 6.876″ push rods restore proper geometry for non-roller 302 engines while providing added stiffness necessary for higher spring pressures. Enginetech hydraulic lifters ensure proper lubrication, stable operation and long-term reliability under aggressive ramp profiles.
Perfect for classic Mustangs, Broncos, Falcons, Fairlanes, F-series trucks and hot rods, this package is built for engine builders who want stronger mid-range performance, exceptional top-end pull and an unmistakably aggressive idle tone. The Competition Cams 31-331-4 Magnum kit with timing set, Stage 2 springs and push rods is a proven way to elevate the performance of any classic Ford 302 hydraulic flat tappet build.
