Description

The Magnum Muscle Advantage The Competition Cams 12-326-4 is the flagship of the Magnum series, designed specifically for the driver who wants a high-performance street machine that isn’t afraid of the drag strip. This is a high-lift, long-duration hydraulic flat tappet cam that demands attention. Because it is a single-pattern grind, it provides a consistent, heavy-hitting power delivery that transforms a standard 350 or 400 into a high-output beast. You should buy this kit if you want the ultimate balance of old-school muscle and modern manufacturing precision.

Rock-Solid Timing Accuracy To ensure your engine’s power remains consistent under the stress of high-RPM pulls, this kit includes a True Double Roller Timing Set. Standard single-row chains are prone to stretching, which causes “timing drift” and robs you of torque and horsepower. This heavy-duty double-row design is 3x stronger than stock, keeping your camshaft and crankshaft in perfect synchronization. This is critical for maintaining peak performance and ensuring your ignition timing stays exact throughout the entire power band.

Aggressive Power Band and Feel This is a high-performance cam engineered for a serious power band of 2,200–6,200 RPM. On the road, this cam feels “electric”—once you cross the 2,500 RPM mark, the engine undergoes a violent transformation, pulling with increasing intensity all the way to the redline. It is the perfect choice for vehicles with a 2,800+ stall converter and performance rear-end gears. You should buy this to make your car feel hundreds of pounds lighter through sheer acceleration.

Superior Valvetrain Integrity To handle the high-revving demands and aggressive ramp speeds of the 286H, this kit includes Premium Redline High-Performance Lifters. These lifters are manufactured with advanced metallurgy to withstand the mechanical stress of high-lift lobes. Featuring precision-ground faces and specialized oiling ports, they ensure a constant film of lubrication—the most critical factor for a successful break-in and long-term durability in a high-output Small Block build.
