Condition: New
– COMPETITION CAMS 01-602-8 BIG MUTHA’ THUMPR: Features an aggressive .569″/.554″ lift and a 107° LSA. You should buy this to get the loudest, choppiest “thumping” idle available while moving your power band to 2,500–6,200 RPM.
– BILLET DOUBLE ROLLER TIMING SET: Includes a CNC-machined billet steel sprocket and a heavy-duty double-row chain. This is critical for preventing chain stretch and maintaining perfect timing accuracy with high-lift performance cams.
– PREMIUM PERFORMANCE ROLLER LIFTERS: Designed with high-capacity needle bearings to handle the rapid ramp speeds of the Big Mutha’ Thumpr. These lifters provide the valvetrain stability required for high-RPM reliability.
– OPTIMIZED FOR GEN 6 454 (1996–2001): Specifically built to fit the unique oiling and bolt patterns of late-model Chevy Big Block engines. This is a no-compromise performance solution for modern heavy-duty blocks.
– RADICAL EXHAUST NOTE: The tight lobe separation creates maximum overlap, resulting in a “nasty” exhaust note that mimics a full-blown drag racer. This cam is designed for owners who want to command attention.

Description
The Meanest Sounding Big Block on the Street If you want your Chevy 454 to have a “nasty” idle that stops traffic, the Competition Cams 01-602-8 Big Mutha’ Thumpr is the ultimate choice. This is the most radical grind in the Thumpr family for the Gen 6 Big Block. It is engineered for the driver who wants that heavy-hitting, choppy race-car sound paired with a power band that excels in the higher RPM ranges.
Maximum Overlap for Maximum Attitude The 01-602-8 features a tight 107° Lobe Separation Angle and long exhaust duration. This specific geometry creates the signature “Thumpr” sound while pushing your power band from 2,500 to 6,200 RPM. It is designed for street/strip applications where you want high-winding performance and an unmistakable presence at any car show or cruise-in.
Built for Strength and Precision Because of the aggressive .569″/.554″ lift, this kit includes Premium Performance Roller Lifters to handle the high intensity of the cam lobes. We’ve also added a Billet Double Roller Timing Set to ensure your timing remains rock-solid under high stress. This is a synchronized system built to turn your Silverado, Suburban, or Sierra into a high-performance machine.
Why You Should Buy: The Ultimate Bolt-In Identity Installing this kit completely transforms the personality of your truck. You get a massive increase in mid-to-high RPM horsepower and the most aggressive idle possible for a street-driven Big Block. Rebuilding your engine is a lot cheaper than buying a new truck—invest in a kit that gives your Chevy the power and sound it deserves.
