Description
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.
Precision Valvetrain Geometry To ensure your engine’s valvetrain is perfectly aligned, we have included Competition Cams High Energy 7.794″ Pushrods. Correct pushrod length is critical for maintaining proper rocker arm geometry. These one-piece, heat-treated steel pushrods are engineered to withstand the fast ramp rates and high-lift stress of the 286H Magnum cam, ensuring that every bit of lift is transferred precisely to the valves without deflection or power loss.
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.
Why This Kit is the Professional Choice The reason to buy this kit is complete valvetrain synchronization. Instead of mixing and matching parts that might not be compatible, you are getting a professionally curated package where every component is designed to work together. From the superior metallurgy of the lifters to the rigid strength of the pushrods and the rock-solid timing set, every part is a safeguard for your high-performance engine.
