Description

Step back into the golden era of horsepower with the Competition Cams 12-212-2 Magnum 280H Camshaft. This is the cam that defined street performance for a generation of muscle car builders. Designed for Small Block Chevy (265-400ci) engines, the 280H Magnum is engineered for the enthusiast who wants a car that sounds aggressive and pulls hard all the way to the redline. It is the perfect choice for a lighter street car—like a Camaro, Nova, or Corvette—equipped with headers, a 4-barrel carburetor, and a desire to go fast on Saturday nights.

The secret to the Magnum’s success is its “Single Pattern” geometry. The 12-212-2 features an identical Duration @ .050 of 230 intake and 230 exhaust, paired with a balanced valve lift of .480”/.480”. This symmetrical design creates a massive, consistent power band from 2,000 to 6,000 RPM. While modern cams try to be subtle, the Magnum is bold. It sacrifices a little bit of low-end smoothness to deliver a rush of mid-range and top-end horsepower that keeps pulling when other cams fall flat. It is specifically designed to work best with higher compression engines and aftermarket intake manifolds.

How does it drive? It gives you the true “Hot Rod” experience. With 280 degrees of advertised duration and a 110-degree Lobe Separation Angle (LSA), this cam produces a rough, choppy idle that lets everyone know you have something serious under the hood. It has a distinct “lope” that sounds healthy and muscular. On the street, it feels eager and responsive once you get the RPMs up. Tech Note: To really enjoy this cam, we recommend a 2,000+ RPM stall converter and rear-end gears of 3.23 to 3.73 to get the car into the power band quickly.

Why buy the 12-212-2? Because it is a proven winner. Competition Cams designed the Magnum series to be easier on valve springs and lifters than ultra-aggressive modern profiles, offering you excellent reliability alongside high performance. If you want a camshaft that is durable enough for daily driving but wild enough for the drag strip, the 280H Magnum is the classic choice that never goes out of style.
