Product Details

This COMP Cams A8 280H-10 camshaft is built with a 230 degrees duration at 0.050 inch lift on both the intake and exhaust sides, making it a solid choice for street machine builds. It’s designed for AMC V8 engines like the 290, 304, 343, 360, and 390, as well as Jeep 4.0L applications, offering a noticeable change from stock performance.

To get the most out of this camshaft, you'll want to pair it with a higher-flowing intake manifold, a torque converter rated around 2500 RPM, and lower rear-end gears. This setup helps ensure the engine can effectively utilize the camshaft's improved breathing characteristics, especially at lower RPMs. The resulting rough idle is a characteristic often desired in performance street applications, signaling a more aggressive engine profile.

This camshaft is intended for builds aiming for a 9:1 compression ratio. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper setup and any additional components needed.
