Description
Description
The Magnum Muscle Advantage The Chevy 12-326-4 is the flagship of the Magnum series, designed for the driver who wants a high-performance street machine with drag strip capabilities. This high-lift, long-duration hydraulic flat tappet cam provides a consistent, heavy-hitting power delivery that transforms a standard 350 or 400 into a high-output beast. You should buy this kit for the ultimate balance of old-school muscle and modern manufacturing precision.
High-RPM Control and Protection The High-Performance Valve Spring Kit is the final piece of the puzzle. Factory springs lack the seat pressure required to control a high-lift cam like the 286H, which can lead to valve float. This kit features springs paired with steel retainers and heat-treated locks, providing the high-tensile strength needed to keep your valves under control while protecting your engine from failure as you approach the 6,200 RPM mark.
Precision Valvetrain Geometry To ensure your engine’s valvetrain is perfectly aligned, we have included 7.794″ High Energy 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.
Rock-Solid Timing Accuracy To ensure your engine’s power remains consistent, this kit includes a True Double Roller Timing Set. 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.
