Description
Description
Dominate the street with the Mutha Thumpr series from Competition Cams. The 08-601-8 is the aggressive “big brother” profile, engineered specifically for non-EFI engines that demand a radical personality. This kit pairs the legendary high-lift camshaft with premium Redline high-performance lifters and a 9-keyway billet steel double roller timing set. It’s a comprehensive valvetrain overhaul designed for maximum mechanical aggression and rock-solid timing accuracy.
The Mutha Thumpr is defined by its brutal, high-overlap idle. With a tight 107-degree lobe separation, it produces a deep, rhythmic, and “choppy” exhaust note that mimics a dedicated race engine. You won’t just hear the difference; you’ll feel the vibration through the floorboards. It transforms your Chevy into an intimidating powerhouse that commands attention at every stoplight, providing the ultimate auditory statement for any hot rod enthusiast.
Expect a violent surge in performance within the 1900–5600 RPM power band. With a heavy .522/.509 lift, this cam moves massive air volumes for explosive mid-range torque and crisp throttle response. The Redline lifters and billet timing set ensure your valvetrain remains stable and synchronized under high-load conditions. Every time you roll onto the throttle, the engine responds with an immediate, snarling urgency that turns raw fuel into pure adrenaline.
Why settle for a standard cam when you can have a legend? The Mutha Thumpr is for the builder who refuses to blend in. It offers the absolute maximum “thump” possible while maintaining the driveability needed for weekend cruising. By including the adjustable 9-keyway timing set, we give you the precision tools to degree your cam perfectly for peak horsepower. This is the complete package for show-stopping sound and hard-hitting Chevy performance.
