COMP CAM 32-602-8 BIG MUTHA THUMPR 243/257 Retro Fit Hydraulic Roller Camshaft, Redline Retro Fit Lifters & 9 Keyway Double Roller Billet Timing Set for Ford 351C 351M 400 – Radical Idle

Description

Wake Up Your Ford V8 with Modern Roller Technology Transform your Ford 351C, 351M, or 400 engine with the ultimate top-end performance package. The Competition Cams 32-602-8 Big Mutha’ Thumpr Retro-Fit Camshaft is the most aggressive in the Thumpr line, designed to provide a high-RPM powerband that excels between 2,500 and 6,200 RPM. Paired with a precision 9-keyway billet double roller timing set, this kit gives you the mechanical accuracy needed to ensure your engine timing remains rock-solid under high-performance street or strip conditions.

The Iconic Muscle Car Experience Installing this Competition Cams Big Mutha’ Thumpr profile completely changes the personality of your vehicle. At idle, you’ll be greeted by an unmistakably rough, hard-hitting lope that commands immediate attention. Once you hit the throttle, the lazy stock feel is replaced by a violent acceleration and a broad torque curve that pulls hard through the upper RPMs. You won’t just see the difference on the speedometer—you will feel the seat-of-the-pants torque and hear the aggressive rhythmic pulse that only a high-energy Big Mutha’ Thumpr grind can provide.

Unmatched Precision and Power Why settle for a “close enough” installation? The included 9-keyway billet timing set allows you to degree your camshaft with absolute precision, ensuring that the intake and exhaust valves open exactly when they should for maximum efficiency. When you combine this level of timing accuracy with the massive .579″ intake lift of the Big Mutha’ Thumpr cam, you aren’t just buying parts—you’re buying the confidence that your engine is optimized for every ounce of available horsepower. This is the definitive choice for the builder who demands a menacing sound, a heavy-hitting feel, and the technical superiority of a high-strength valvetrain.

The Redline Lifter Advantage Don’t settle for standard lifters when running the most aggressive Thumpr profile from Competition Cams. The included Redline Premium Retro-Fit Lifters feature a link-bar design that keeps the rollers perfectly aligned with the cam lobes. CNC-machined and heat-treated, these lifters are built to handle the higher spring pressures required for performance roller setups, providing peace of mind and a quieter, more reliable valvetrain.
