Description
Description
The Competition Cams 31-601-5 Thumpr Camshaft and Enginetech Performance Hydraulic Lifters Kit is designed for Ford small block engines that need more power, stronger throttle response, and the aggressive Thumpr idle sound. This hydraulic flat tappet cam features 279/296 degrees advertised duration, 227/241 degrees duration at .050, .491/.476 lift, and a 107-degree LSA. These specifications create high valve overlap for a hard-hitting, choppy idle while increasing low and mid-range torque for real street performance gains.
With an operating range of 2,000 to 5,800 RPM, this camshaft is ideal for Ford 351W 289, and 302 engines found in classic Mustangs, Falcons, Fairlanes, street rods, and other performance builds. The tight 107 LSA and long exhaust duration help improve cylinder scavenging, throttle response, and acceleration, making the engine feel noticeably stronger compared to stock or mild camshafts.
The included Enginetech performance hydraulic lifters are built for high-quality oil control and durability, providing stable operation with the aggressive Thumpr cam profile. Together, this cam and lifter combination delivers improved drivability, better mid-range power, and the signature Thumpr exhaust tone that enthusiasts want.
This kit is an excellent upgrade for builders who want more torque, a louder and more noticeable idle, and a major improvement in overall engine attitude and performance. It is best used with higher stall converters, upgraded valve springs, tuning, intake and exhaust upgrades, and typical street-performance modifications.
If you want a camshaft that transforms the sound and feel of your Ford small block while still delivering real horsepower and torque improvements, the Comp 31-601-5 Thumpr cam and lifters kit is one of the most effective and popular choices for street and street/strip builds.
