It's built for high-performance street and strip applications, aiming to give your engine a more aggressive feel and sound.
The camshaft features a 234/249 degree duration at 0.050 inch lift, which contributes to its rough idle and strong performance characteristics. To get the most out of this camshaft, it requires a minimum of 9:1 compression, a torque converter with at least a 2500 RPM stall speed, and supporting modifications like an upgraded intake, rear gears, and headers. These components work together to help the engine breathe better and handle the increased performance.
When installing this camshaft, be aware that it's intended for performance builds and will result in a noticeable, rough idle. It's not CARB approved, so it cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and compatibility details.
