– PRECISION Competition Cams SPECS: Features the legendary 12-205-2 (252H) grind. Specs include 252° Advertised Duration, 206° Duration @ .050″, and a lift of .425″/.425″. This is the sweet spot for high-velocity intake charges and massive low-end torque.
– HIGH-PERFORMANCE SPRINGS & STEEL HARDWARE: Includes a matched set of valve springs engineered for the 252H profile, paired with heavy-duty steel retainers. These provide the necessary seat pressure to eliminate valve float and ensure the valves snap shut accurately at high RPM.
– 7.794″ PUSH RODS: Includes a full set of 5/16″ diameter one-piece hardened push rods. This specific length is the factory standard for SBC flat-tappet engines, ensuring correct rocker arm geometry and preventing energy-robbing deflection under load.
– TRUE DOUBLE ROLLER TIMING SET: Features a high-strength double-row chain and heat-treated gears. This setup provides 3x the strength of a stock chain, maintaining perfect valve timing and preventing the “chain slap” common in high-mileage engines.
– PREMIUM REDLINE LIFTERS: High-performance hydraulic flat-tappet lifters designed with precision-machined oiling holes for maximum lubrication. These are built to survive the critical break-in period and provide years of quiet, maintenance-free service.

Description
Unlock True Small Block Performance Upgrade your street machine with a camshaft and lifter combination designed for maximum low-to-mid-range torque. The Competition Cams 12-205-2 High Energy Camshaft is specifically engineered for street engines with an 8:1 to 9:1 compression ratio, making it the ideal choice for performance rebuilds. This kit transforms your vehicle’s power delivery, providing a noticeable increase in both gas mileage and throttle response throughout the 800–4,800 RPM range, ensuring your Chevy stays ahead of the curve.
Optimized Valvetrain Stability To handle the increased performance, this kit includes High-Performance Valve Springs matched with Steel Retainers and Guides. These components are essential for preventing valve float at higher RPMs and ensuring consistent seat pressure. When paired with our 7.794″ Hardened Push Rods and Premium Redline High-Performance Lifters, you get a perfectly synchronized valvetrain that remains stable, quiet, and reliable under the most demanding street conditions.
Precision Timing and Strength To complete this ultimate 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 Street Sound Expect a smooth, stable idle that doesn’t sacrifice that classic V8 muscle feel. The 110-degree lobe separation angle provides plenty of engine vacuum to support power brakes and stock accessories, making it a “no-compromise” street cam. It offers a refined, crisp tone that hints at the power underneath without the aggressive, rough lope that makes daily driving difficult. It is the perfect “sleeper” camshaft for those who want their truck or car to sound professional and perform efficiently.
