Description

When you install the Competition Cams 54-470-11, you’re choosing a camshaft that was engineered for serious performance in GM LS engines with rectangular port heads. With a massive lift (.621″/.624″) and extended duration (235°/251° @ .050), this cam allows the engine to breathe deeper and longer than factory profiles — translating into quicker throttle response, stronger mid-range punch and high-RPM horsepower that climbs harder.

From the moment you hit the throttle, you’ll feel a sharper edge in how the engine responds. The earlier valve opens and later valve close allow more air-fuel mixture in and better exhaust flow out — giving you better cylinder fill and higher effective compression during the power stroke. Real-world, that means quicker acceleration, better passing power and a more aggressive engine character.

As RPM climbs toward the upper peaks, the 54-470-11 keeps your LS breathing efficiently thanks to its duration and lift combination. You’ll notice that the engine stays strong where lesser cams start to fade. The 113° lobe separation angle moderates the idle tone just enough to keep it street-friendly, while still delivering that performance sound and feel that separates a built engine from stock.

Ultimately, this cam is for drivers who want more than just a mild upgrade. It’s for those building higher-flow LS engines with aftermarket heads and strong supporting mods, who want noticeable changes in how their engine drives, sounds and performs. If you’re ready for a real step up in performance, this cam delivers.
