Description
Description
Turn your Chevy 396–454 big block into a true Thumpr with this complete valvetrain package featuring the Competition Cams 11-600-8 Thumpr hydraulic roller camshaft, Redline Performance link-bar lifters and a billet steel double roller timing set.
The 11-600-8 grind delivers .547″/.530″ lift, 283°/303° advertised duration, 227°/241° @ .050 and a tight 107° lobe separation angle. This combination is designed to dramatically improve airflow and cylinder filling while delivering the aggressive Thumpr series exhaust note. The high lift opens the valves deep into the head’s high-efficiency flow zone, while the extended duration keeps them open long enough at peak velocity to build serious torque and horsepower from about 1,900–5,500 RPM.
The 107° LSA creates significant overlap, which sharpens throttle response and produces the classic Thumpr choppy idle that sounds radical at every stoplight. With proper compression, gearing and converter, this cam delivers a very hard-hitting mid-range and strong street/strip performance while still being usable on pump gas.
Redline Performance link-bar hydraulic roller lifters are included to match the cam’s aggressive lobe design. The billet steel double roller timing set uses hardened gears and a dual-roller chain to keep cam timing precise, reduce stretch and protect your investment at high RPM.
This kit is an excellent choice for big block–powered muscle cars, street rods and trucks where you want maximum sound and attitude along with real performance gains. If you want your Chevy 396–454 to hit hard, pull strong and have that unmistakable Thumpr lope, this Competition Cams 11-600-8 package with Redline lifters and a billet steel timing set is exactly what you’re looking for.
