– COMPETITION CAMS 12-672-4 “30-30” GRIND: Precision-engineered to replicate the legendary 302/327 Z28 solid lifter sound. You should buy this to get the most aggressive “rumpity-rump” idle available in a hydraulic street cam with modern horsepower gains.
– ULTRA-HIGH RPM RANGE (2,300–6,500 RPM): Designed for maximum top-end performance and high-speed breathing. You should buy this because it continues to pull hard where other cams peak and fall off.
– VALVE LIFT SPECS (.483″ INTAKE / .477″ EXHAUST): High-lift geometry designed to shove the valves deep into the cylinders. You should buy this to drastically increase high-RPM airflow and top-speed horsepower.
– HIGH-PERFORMANCE VALVE SPRINGS: Specifically rated for the aggressive lift and RPM of this “30-30” grind. You should buy these to eliminate valve float and ensure your engine pulls cleanly all the way to 6,500 RPM.
– STEEL RETAINERS & HARDENED LOCKS: High-strength valvetrain hardware. You should buy these to replace weak factory pieces and guarantee valve security during extreme high-RPM driving.

Description
The Reigning King of Nostalgia Performance Step into the top tier of the Nostalgia Plus series with the Competition Cams 12-672-4 Camshaft. This total valvetrain package is specifically designed to replicate the legendary “30-30” Duntov solid lifter profile used in the high-winding 302 and 327 powerhouses of the late 1960s. While it captures that iconic, high-strung personality, this modern hydraulic flat tappet grind eliminates the constant maintenance of a solid cam while delivering even more mid-range torque and top-end scream.
Maximum Attitude and High-RPM Dominance The Competition Cams 12-672-4 is the most aggressive in the line, and it will completely redefine your Chevy. When you fire this engine up, you get a heavy, hard-hitting, and choppy professional idle that leaves no doubt about the power under the hood. You should buy this because it is a “top-end” specialist—with an operating range pushing all the way to 6,500 RPM, it transforms your Small Block into a high-revving masterpiece that thrives in the upper reaches of the tachometer.
Professional Grade Valvetrain Stability To handle this cam’s aggressive profile and 6,500 RPM potential, this kit includes High-Performance Valve Springs, Steel Retainers, and Hardened Locks. These components provide the exact seat pressure needed to prevent valve float, keeping your valvetrain stable when you’re pushing the engine to its limit. Paired with Redline High Performance Lifters, you get superior oil metering and durability that protects your cam lobes from the stresses of high-lift performance.
Total Timing and Geometry Precision Accuracy is everything in a high-revving Small Block. This kit includes a True Double Roller Timing Set to eliminate timing chain slack and a set of 7.794″ Length Pushrods to maintain rigid valvetrain geometry. By replacing everything from the timing gears to the valve locks in one shot, you eliminate the mechanical “weak links” that cause power loss and engine wear. Rebuilding your engine is a lot cheaper than buying a new truck, and this is the professional way to give your Chevy a high-performance second life with zero compromises.
