Description
Description
This kit includes the Competition Cams 31-602-5 Thumpr hydraulic flat tappet camshaft and Enginetech performance hydraulic lifters. It is designed for Ford 289, 302, and 5.0L small block engines that need a major improvement in sound, throttle response, and overall performance. The camshaft features 287 and 304 degrees advertised duration, 235 and 249 degrees duration at .050, .500 and .486 lift, and a tight 107-degree lobe separation angle. These aggressive specifications create the classic Thumpr lopey idle while improving cylinder scavenging and delivering strong mid-range torque.
Operating best in the 2,200 to 6,200 RPM range, this camshaft provides harder acceleration, quicker throttle response, and a more exciting driving experience. The cam uses the early Ford firing order of 1-5-4-2-6-3-7-8 for correct engine timing and stable performance. The Enginetech hydraulic lifters included in the kit are engineered for flat tappet performance builds and provide smooth lifter action, proper oil control, and improved valvetrain stability under higher lift conditions.
This cam and lifter set is ideal for street rods, classic Mustangs, and performance engines wanting a more aggressive idle and stronger mid-range power. If you want a camshaft that significantly improves the sound and performance of a small block Ford engine, the Comp Cams 31-602-5 Thumpr cam with Enginetech lifters is one of the most effective upgrades available.
