Description

This master performance kit for your Chevy Small Block is built for the high-revving enthusiast, featuring the legendary Competition Cams 12-250-3 (XE284H). We have engineered this package for serious street-strip performance by combining this aggressive profile with 7.794″ High Energy Pushrods, Redline High-Performance Lifters, and a True Double Roller Timing Set.

Product Description

The Xtreme Energy Advantage The Competition Cams 12-250-3 is the pinnacle of the Xtreme Energy series for street-strip applications. Utilizing advanced fast-ramp technology, this cam snaps the valves open quickly to build massive “area under the lift curve.” This results in significantly better throttle response and more top-end power than traditional lazy-lobe cams. You should buy this kit to give your Chevy the absolute maximum performance possible from a hydraulic flat-tappet setup while still maintaining the vacuum needed for power brakes.

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 XE284H 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.
