What kind of powerband can I expect with this camshaft?

This camshaft is designed to deliver steady power throughout a broad operating range. It's particularly effective when paired with aftermarket intake and exhaust upgrades to maximize its performance potential across the RPM spectrum.

What supporting modifications are recommended for this camshaft?

For optimal performance, it is recommended to pair this camshaft with aftermarket airflow improvements for both the inlet and exhaust systems. This typically includes upgraded cylinder heads, intake manifolds, and exhaust headers.

Is this camshaft compatible with factory cylinder heads?

Yes, the LSR Cathedral Port design is optimized for factory cathedral port cylinder heads commonly found on GM LS engines. However, its performance is significantly enhanced when the engine's overall breathing capacity is increased with other modifications.

Product Details

This COMP Cams camshaft, part number 54-457-11, features a 223/231 degree intake/exhaust duration split with a 112-degree lobe separation angle. This specific grind is designed for GM LS GEN III and GEN IV engines, including popular displacements like 5.7L LS1 and 6.0L LS2, and is intended to provide steady power throughout a broad operating range. It utilizes a hydraulic roller design, which helps maintain consistent valve lift and timing without the need for frequent adjustments.

For this camshaft to perform at its best, it's recommended to pair it with aftermarket airflow improvements for both the intake and exhaust systems. This means considering upgraded cylinder heads, intake manifolds, and exhaust headers to help the engine breathe more freely. The LSR Cathedral Port design is optimized for the factory cathedral port cylinder heads found on many LS engines, but its effectiveness is significantly enhanced when the engine's overall breathing capacity is increased. This camshaft is a solid option for builders looking to extract more usable power from their LS-based engine, whether it's in a performance car or a truck.

This camshaft fits a wide variety of GM vehicles, including models like the Chevrolet Camaro, Corvette, and Silverado trucks, as well as Cadillac CTS and Buick LaCrosse. It's important to note that this part is not CARB approved and cannot be shipped to California. Always consult the manufacturer's installation instructions for specific details regarding required supporting modifications and proper installation procedures.
