– COMPETITION CAMS 01-427-8 PERFORMANCE CAM: Expertly ground with an aggressive .560″/.580″ lift and a 114° LSA. You should buy this to unlock a vicious power band from 3,000 to 6,000 RPM, providing the high-end horsepower needed for serious street performance.
– BILLET DOUBLE ROLLER TIMING SET: Features a CNC-machined billet steel crank sprocket and a heavy-duty double-row chain. This is a critical upgrade for maintaining absolute timing accuracy and preventing the timing flutter or chain stretch that occurs with high-mileage stock sets under high-performance stress.
– PREMIUM PERFORMANCE ROLLER LIFTERS: These units are engineered with high-capacity needle bearings and precision-ground axles. You need these to provide the critical valvetrain stability required to handle the aggressive .580″ lift and ensure your lifters remain quiet and reliable at high engine speeds.
– OPTIMIZED FOR GEN 6 454 (1996–2001): Specifically tailored for the unique oiling paths and 1-piece rear main seal architecture of late-model Chevy Big Blocks found in Silverado 2500/3500 and Sierra models.
– AUTHORITATIVE STREET IDLE: The 114° LSA creates a distinct, performance-oriented lope at idle. It tells everyone that your 7.4L is built for high-output performance while still maintaining the vacuum levels needed for power brakes.

Description
The Ultimate Performance Evolution for Your Gen 6 Big Block If you want to push your Chevy 454 into the realm of true high-performance street machines, the Competition Cams 01-427-8 is the definitive choice. This camshaft is a major step up from standard profiles, specifically engineered for the 1996–2001 Gen 6 block owner who wants a broad, aggressive power band that doesn’t fall flat at high speeds. It is the perfect upgrade for a performance-built Chevy Silverado or a high-output street rod.
Aggressive Lift for Serious Airflow The 01-427-8 is a precision-engineered hydraulic roller profile featuring a heavy-hitting .560″/.580″ lift and a stable 114° Lobe Separation Angle. This combination is the key to its athletic personality; it creates a power band that starts pulling hard at 3,000 RPM and carries that momentum all the way to 6,000 RPM. The 114° LSA ensures you still have an authoritative, performance idle while maintaining enough manifold vacuum to keep your power brakes and accessories working like they should.
What to Expect: A High-Winding Street Warrior Once installed, this cam completely transforms how your 7.4L responds. You’ll experience a violent surge in mid-to-high range power that makes the engine feel much larger and more capable than stock. The increased lift allows the Big Block to breathe deep, providing a crispness and “snap” that defines a properly tuned performance engine. Whether you are hitting the track or just want the baddest truck on the street, this cam delivers relentless, high-RPM thrust.
Why You Should Buy: The Synchronized Performance Trio This listing is the top choice for enthusiasts who demand parts that are designed to play well together. By matching this high-lift Competition Cams profile with Premium Performance Roller Lifters and a Billet Double Roller Timing Set, you are building a valvetrain that can handle 6,000 RPM with superior stability and perfect timing accuracy. You should buy this kit to gain a synchronized performance advantage, ensuring your Chevy has the strength to outclass anything in its path.
