This premium valvetrain upgrade pairs the Competition Cams 31-238-3 Xtreme Energy hydraulic flat tappet camshaft with Enginetech high-performance hydraulic lifters and a true double roller timing set. Designed for Ford 221, 260, 289 and 302 small block hydraulic flat tappet engines, this kit delivers significant improvements in torque, throttle response, airflow efficiency and top-end horsepower while maintaining dependable street drivability. The Competition Cams 31-238-3 features .493"/.500" lift, 262°/270° advertised duration, 218°/224° duration at .050 and a 110-degree lobe separation angle. These specs place the cam squarely in the street/strip performance category. The high lift opens the valves deeper into the cylinder head's flow stream, increasing volumetric efficiency. The added duration keeps the valves open longer for improved cylinder filling and combustion, leading to stronger mid-range torque and improved high-RPM performance. The 110° LSA introduces controlled overlap, enhancing exhaust scavenging, throttle response and overall engine character while still maintaining suitable vacuum for power brakes. The included true double roller timing set provides precise timing control through its dual-roller chain and machined sprockets. This helps maintain accurate valve events, reduce timing drift and support the aggressive lobe profile. Matched Enginetech hydraulic lifters ensure proper lubrication, smooth travel and long-term reliability. Perfect for classic Mustangs, Broncos, Falcons, Fairlanes, F-series trucks and street rods, this camshaft kit is ideal for builders looking to significantly increase performance without sacrificing everyday usability. The Competition Cams 31-238-3 kit with lifters and a double roller timing set is a proven combination for classic Ford small-block engines seeking more power, more response and a more exciting performance sound.
