Comp Cam 31-246-3 Xtreme Energy 230/236 Camshaft with Performance Lifters and Double Roller Timing Set – Strong Torque - .519/.523 Lift, 274/286 Duration – FITS Ford 260 289 302 SBF Engines

This complete camshaft and valvetrain upgrade package pairs the Competition Cams 31-246-3 Xtreme Energy hydraulic flat tappet camshaft with Enginetech high-performance lifters and a true double roller timing set. Designed for Ford 221, 260, 289 and 302 hydraulic flat tappet engines, this kit delivers major increases in torque, throttle response, airflow efficiency and high-RPM horsepower. The 31-246-3 grind features .519"/.523" lift, 274°/286° advertised duration, 230°/236° duration @ .050 and a 110° lobe separation angle. With over .519" lift, the cam opens the valves deep into the cylinder head’s high-velocity airflow region, significantly improving both intake and exhaust efficiency. The long duration keeps valves open during peak flow, resulting in stronger mid-range torque, quicker RPM climb, better combustion efficiency and extended high-RPM performance. The 110° LSA introduces controlled valve overlap, improving exhaust scavenging and intake charge velocity. This gives the engine a sharper throttle feel, quicker response and a powerful, aggressive performance idle with a distinct lope. The included true double roller timing set reduces chain stretch, stabilizes valve events and ensures reliable long-term cam timing at elevated RPM levels. Enginetech hydraulic lifters are matched to the cam’s ramp profiles for smooth operation, proper lubrication and dependable valvetrain performance. This kit is ideal for classic Mustangs, Broncos, Falcons, Fairlanes, street rods and vintage Ford trucks running hydraulic flat tappet engines. It works well with upgraded intakes, headers, carb/EFI tuning or mild cylinder head work. If you’re looking to wake up your Ford small block with a harder-pulling, sharper-sounding and more responsive performance package, this 31-246-3 timing set and lifter kit is the right upgrade.
