COMP Cams Hustler 603/604 Crate Engine Hydraulic Roller Stage 2 Camshaft

This COMP Cams Hustler 603/604 Stage 2 hydraulic roller camshaft is designed for racers looking to get more power out of their '87 and newer GEN 1 Chevrolet 305-350 small block engines that came with a factory roller camshaft. You'll receive the camshaft itself, ready for installation into your engine. This camshaft is intended to provide a noticeable horsepower gain over the original equipment cam, giving your engine a more aggressive feel and sound, especially at idle, which may indicate it's not a factory piece.

The 603/604 designation refers to the camshaft's lobe separation angle and intake/exhaust duration, key specs that determine how the engine breathes and performs. This Stage 2 grind is a popular choice for those seeking improved performance without requiring extensive modifications to the rest of the engine. It's built to work with factory roller valvetrain components, simplifying the installation process for mechanics familiar with these small block Chevy engines. While it offers a significant performance upgrade, be aware that it is not CARB approved and cannot be shipped to California.

When installing this camshaft, it's important to follow the manufacturer's recommended procedures to ensure optimal performance and longevity. This upgrade is a solid option for anyone wanting to extract more power from their classic small block Chevy, giving it that racer's edge.
