Unlock the full performance potential of your Ford small block with this Competition Cams 31-242-3 Xtreme Energy camshaft and Enginetech high-performance hydraulic lifter package. Perfect for 221, 260, 289 and 302 hydraulic flat tappet engines, this cam is engineered to deliver a dramatic improvement in throttle response, mid-range torque and upper-RPM horsepower—while maintaining enough street manners for reliable everyday driving. The 31-242-3 features aggressive performance specifications: .509"/.512" valve lift, 268°/280° advertised duration, 224°/230° duration at .050 and a 110° lobe separation angle. With more than half an inch of lift, the cam opens the valves deep into the cylinder head's high-velocity airflow zone, improving intake charge volume and exhaust evacuation. The extended duration keeps valves open longer during peak flow, enhancing combustion efficiency and producing a noticeably stronger and more responsive engine throughout the 1,600–5,800 RPM range. The 110° LSA adds controlled overlap that improves exhaust scavenging, giving the engine a sharper, more aggressive personality. This overlap also results in a crisp performance idle with a healthy lope, offering unmistakable sound and attitude while still preserving enough vacuum for power brakes and stable street operation. Whether your engine uses stock components, mild bolt-ons or upgraded heads, this cam delivers: quicker throttle response, more mid-range punch, stronger pull through higher RPM and a richer performance exhaust note. It is an excellent choice for classic Mustangs, Falcons, Fairlanes, Broncos, street rods and vintage Ford trucks running hydraulic flat tappets. Matched Enginetech high-performance hydraulic lifters ensure smooth valvetrain motion, stable lubrication and long-term durability under the cam's aggressive profile. Together, this cam and lifter set provides a reliable, high-value upgrade that transforms the driving experience of classic Ford small block engines. If you want your Ford small block to sound meaner, pull harder and feel significantly more powerful—this 31-242-3 Xtreme Energy camshaft kit is the ideal choice.
