– COMPETITION CAMS 01-451-8 MARINE CAM: Expertly engineered with .547″/.547″ lift and a 2,200–5,800 RPM range. You should buy this to gain superior top-end horsepower and a power curve specifically optimized for high-performance jet and pleasure boats.
– BILLET DOUBLE ROLLER TIMING SET: Features a CNC-machined billet steel crank sprocket and a heavy-duty double-row chain. This is a mandatory marine upgrade to maintain exact cam timing and eliminate the chain stretch that occurs during sustained high-RPM operation in open water.
– PREMIUM PERFORMANCE ROLLER LIFTERS: These high-output lifters feature high-capacity needle bearings and precision-ground axles. You need these to provide the rock-solid valvetrain stability required for the aggressive .547″ lift, ensuring your engine remains quiet and durable under extreme marine loads.
– OPTIMIZED FOR GEN 6 454 (1996–2001): Designed specifically for the late-model Chevy Big Block architecture. This is a plug-and-play high-performance solution that respects the unique oiling and 1-piece seal requirements of your Gen 6 block.
– AGGRESSIVE MARINE IDLE: The 112° LSA provides a performance-oriented lope at idle. It gives your boat an intimidating sound profile at the marina while still allowing for reliable low-speed maneuvering in no-wake zones.

Description
The Ultimate High-RPM Evolution for Your Gen 6 Big Block For the boater pushing for maximum top-end performance and explosive mid-range pull, the Competition Cams 01-451-8 is the definitive step up. This camshaft is precision-ground for 1996–2001 Gen 6 Chevy blocks and is specifically engineered to thrive in the high-stress, water-cooled environment of performance marine engines. It is a favorite for jet boats running an “A” impeller and performance cruisers looking to significantly extend their power band.
Dominating the High-RPM Range With a symmetrical .547″/.547″ lift and a broader 2,200–5,800 RPM range, the 01-451-8 shifts the power focus higher than standard marine cams. The 112° Lobe Separation Angle is critical here; it helps the engine work against restrictive marine exhaust backpressure while maintaining excellent cylinder pressure. The result is an engine that sounds menacing at the dock with a rhythmic lope, but transforms into a high-winding powerhouse once you hit open water.
What to Expect: High-Velocity Response This kit is built for speed. You will notice a dramatic increase in top-end horsepower and a throttle response that feels “electric” in the upper RPM reaches. While it demands a higher operating range, it still maintains enough manifold vacuum for essential accessories. This is the hardware you need to maintain higher sustained speeds and achieve a faster, more aggressive plane under heavy load.
Why You Should Buy: The Performance Synergy By pairing this aggressive Competition Cams profile with Premium Performance Roller Lifters and a Billet Double Roller Timing Set, you are building a valvetrain designed for longevity at 5,000+ RPM. You should buy this kit to ensure your Chevy has the synchronized internal strength and absolute timing accuracy to handle high-lift ramp speeds without failure, giving you the confidence to hold the throttle pinned across the lake.
