COMP CAM 12-210-2 High Energy 218/218 268H Camshaft Kit | .454"/.454" | High-Performance Lifters | True Double Roller Timing | FITS Chevy SBC 283 327 350 400 5.7 5.7L | Aggressive Street Performance

Unlock Aggressive Street Performance If you are looking to move beyond "entry-level" upgrades, the Competition Cams 12-210-2 (268H) is the definitive choice for the serious street enthusiast. As a flagship profile in the High Energy series, the 268H is engineered for engines with a 9:1 to 10:1 compression ratio. It delivers a substantial increase in power from 1,500 to 5,500 RPM, transforming your Chevy into a much more aggressive machine that pulls hard through every gear. Superior Valvetrain Integrity High-performance camshafts require lifters that can keep up with faster ramp rates and increased lift. This kit includes Premium Redline High-Performance Lifters, which are manufactured with advanced metallurgy to withstand the mechanical stress of a performance flat-tappet build. These lifters feature precision-machined oiling ports to ensure a constant film of lubrication between the lobe and the lifter face, preventing premature wear and ensuring a successful break-in. Precision Timing and Strength To complete this ultimate valvetrain overhaul, we have added a True Double Roller Timing Set. This heavy-duty upgrade replaces standard single-row chains that are prone to stretching and timing drift. The double-row design offers superior strength and durability, ensuring your engine's timing remains rock-solid even under high-load conditions. With precision-machined gears and a pre-stretched chain, this timing set provides the mechanical accuracy needed to get the most out of your new Competition Cams profile. The Signature "Muscle Car" Tone This is the camshaft that provides the classic, unmistakable V8 sound. The 268H offers a noticeably lopey, high-performance idle that signals serious power under the hood. While it sounds aggressive at a stoplight, the 110-degree lobe separation angle is carefully designed to maintain enough manifold vacuum for power brakes and stock accessories. It provides the perfect balance: a street-legal "sleeper" sound that backs it up with real-world acceleration.
