– COMPETITION CAMS 01-456-8 MARINE CAM: Expertly ground with an aggressive .566″/.566″ lift and a 112° LSA. You should buy this to unlock an extreme marine power band from 2,800 to 6,200 RPM, delivering the massive top-end horsepower required for high-performance hulls.
– PREMIUM PERFORMANCE ROLLER LIFTERS: Built with high-capacity needle bearings and precision-ground axles. You need these to provide the superior stability required to handle the high ramp speeds of the .566″ lift, preventing lifter “pump up” and ensuring long-term durability during high-speed runs.
– 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. This is a high-output performance solution built for modern marine durability.
– INTIMIDATING PERFORMANCE IDLE: The 112° LSA produces a sharp, rhythmic lope that sounds incredible through marine headers. It provides a true “race-boat” personality while maintaining the vacuum necessary for consistent starting and low-speed docking.
– MAXIMUM TOP-SPEED POTENTIAL: By shifting the power band up to 6,200 RPM, this cam allows your engine to process a massive volume of air, resulting in higher GPS top speeds and the ability to pull more aggressive prop or impeller pitches.
