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 kit is engineered for the serious enthusiast who wants 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 Because this cam features high-intensity lobes and a massive RPM ceiling, we have paired it with Redline High Performance Lifters. These lifters are precision-engineered with advanced oil metering to ensure they stay stable and quiet even as you approach 6,500 RPM. Rebuilding your engine is a lot cheaper than buying a new truck, and by choosing this matched cam-and-lifter pair, you are ensuring your valvetrain has the durability to handle the most aggressive "Nostalgia" profile Competition Cams offers.
