Description
Description
This complete performance kit includes the Competition Cams 31-601-5 Thumpr hydraulic flat tappet camshaft, Enginetech hydraulic lifters, a true double roller timing set, and a set of 6.876-inch performance push rods. It is designed for Ford small block 221, 260, 289, and early 302 engines that need a major upgrade in sound, torque, and driving performance. The camshaft features 279 and 296 degrees advertised duration, 227 and 241 degrees duration at .050, .491 and .476 lift, and a 107-degree lobe separation angle. These specifications create high valve overlap for the aggressive Thumpr lopey idle while improving cylinder scavenging and stronger mid-range torque.
Operating in the 2,000 to 5,800 RPM range, this camshaft delivers quicker throttle response, stronger acceleration, and a noticeable improvement in overall engine feel. The cam uses the early SBF firing order of 1-5-4-2-6-3-7-8 for correct operation. The included double roller timing set helps maintain accurate cam timing by reducing chain stretch and improving long-term durability. Enginetech hydraulic lifters provide smooth operation and stable oil control with this aggressive profile.
The 6.876-inch performance push rods complete the package by maintaining proper valvetrain geometry and offering increased strength for high-lift applications. This kit is ideal for classic Ford builds, street rods, and performance engines wanting a deeper idle, better torque, and a major upgrade in sound and drivability.
If you want a camshaft kit that truly transforms a small block Ford engine, this combination of Thumpr camshaft, lifters, timing set, and 6.876-inch push rods delivers a noticeable improvement in sound, power, and overall performance.
