Description

This kit for the Chevy Small Block is built around the high-performance Competition Cams 12-250-3 (XE284H). This package combines the most aggressive street-strip profile in the Xtreme Energy series with a True Double Roller Timing Set and Redline High-Performance Lifters for a rock-solid, high-revving valvetrain.

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.

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 high-output builds to ensure 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 2,300–6,400 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 XE284H, 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.
