Description
Wake up your heavy truck, 4×4, or daily cruiser with the Competition Cams 12-234-2 Xtreme Energy (XE256H). If you use your Small Block Chevy (265-400ci) for towing, hauling, or just navigating city traffic, you don’t need high-RPM horsepower—you need torque. The XE256H is engineered with Competition Cams’ advanced “Xtreme Energy” technology, which uses aggressive lobe profiles to snap the valves open faster than stock cams. This results in unparalleled throttle response and a massive boost in low-end power that you can feel the instant you touch the gas pedal.
The specs tell the story of a cam built for utility and efficiency. The 12-234-2 features a Duration @ .050 of 212 intake and 218 exhaust, with a valve lift of .447”/.454”. This geometry places the power band squarely between 1,000 and 5,200 RPM. While stock cams feel lazy and sluggish off the line, the XE256H provides the immediate “grunt” needed to get heavy vehicles (like Suburbans, K5 Blazers, and C10s) moving effortlessly. It is the perfect upgrade for anyone looking to improve towing capability and often helps increase fuel efficiency by optimizing engine airflow.
How does it drive? It is smooth, civilized, and incredibly responsive. With a 110-degree Lobe Separation Angle (LSA), this camshaft produces a smooth idle with just a hint of muscle tone, but its primary focus is drivability. It generates excellent manifold vacuum, ensuring your power brakes, steering, and HVAC controls function perfectly. Best of all, it is designed to work seamlessly with stock torque converters and standard rear-end gears, meaning you don’t need to spend thousands on supporting modifications to enjoy it.
Why choose the XE256H? Because it brings modern performance technology to your classic engine. Competition Cams designed this profile to be the ultimate “set it and forget it” upgrade. It offers significantly more area under the lift curve than a standard RV cam, giving you more power without the drawbacks of a rough idle. Whether you are restoring a vintage pickup or refreshing a family cruiser, the 12-234-2 is the smartest investment you can make for real-world driving performance.
