Description

Capture the spirit of the golden age of hot rodding with the Competition Cams 12-213-3 Magnum 292H Camshaft. This is the legendary “Magnum” grind that defined street/strip performance for decades. Designed for Small Block Chevy (265-400ci) engines, this camshaft is not for a mild daily driver; it is engineered for the serious enthusiast who has built an engine with higher compression, lower gears, and a desire for high-RPM horsepower. If you want that classic, loping idle and a top-end charge that pulls all the way to the redline, the 292H Magnum is the proven choice that delivers reliable, brute force power.

The specs on the 12-213-3 are pure racing heritage. This is a Single Pattern Camshaft, meaning the intake and exhaust specs are identical: Duration @ .050 of 244 intake and 244 exhaust, with a balanced valve lift of .501”/.501”. This symmetrical geometry is perfect for high-compression engines and free-flowing exhaust systems, creating a massive power band that surges from 2,500 to 6,500 RPM. Unlike modern split-pattern cams that try to smooth things out, the Magnum series hits hard and keeps pulling, making it a favorite for bracket racers and pro-street builds.

How does it behave on the street? It has an attitude. With 292 degrees of advertised duration and a 110-degree Lobe Separation Angle (LSA), this cam produces a rough, choppy idle that shakes the car and lets everyone know you aren’t running stock parts. It requires a bit of RPM to wake up, but once you hit 3,000 RPM, the acceleration is violent. Tech Requirement: Because of the large duration and .501 lift, this cam requires a 2,500+ RPM stall converter, headers, intake upgrades, and rear-end gears of 3.73 or lower to operate effectively.

Why choose the 12-213-3? Because sometimes the old ways are the best ways. Competition Cams designed the Magnum series to be easier on valvetrain components than ultra-aggressive modern ramps, providing excellent reliability for high-performance engines. You get a camshaft that is durable enough for street cruising but capable of screaming down the drag strip on the weekends. If you have the compression and the gears to support it, the 292H Magnum offers a driving experience that is raw, exciting, and undeniably American.
