Description
Description
This performance upgrade kit pairs the Competition Cams 11-601-8 Mutha’ Thumpr hydraulic roller camshaft with Redline Performance link-bar lifters to deliver a dramatic improvement in power, throttle response and sound for Chevy 396–454 big block engines.
The 11-601-8 features .558″/.542″ lift, 291°/311° advertised duration, 235°/249° @ .050 and a tight 107° lobe separation angle. These aggressive specs open the valves higher and keep them open longer, maximizing airflow and cylinder filling. The result is stronger mid-range torque, harder acceleration and a noticeably more responsive big block.
The tight 107° LSA increases overlap, producing the legendary Thumpr-series choppy idle that gives any big-block Chevy a loud, unmistakable muscle-car tone. This cam is engineered for engines equipped with performance heads, headers, intake upgrades and proper tuning.
Redline Performance link-bar hydraulic roller lifters are included to match the cam’s aggressive ramp design. These lifters provide stable roller control, excellent lubrication and reliable long-term performance in high-lift applications.
For big-block Chevy owners looking for real power gains, sharper throttle feel, a harder-hitting mid-range and the strongest performance idle on the street, this 11-601-8 cam and lifter combo is the perfect choice.
