What kind of idle can I expect with this camshaft?

This COMP Cams camshaft is designed to produce a noticeable idle. It's part of the 'Xtreme 4x4' series, meaning it offers a more aggressive sound and feel than a stock camshaft, letting you know it's there.

What other modifications are recommended when installing this camshaft?

For optimal performance, it's recommended to use headers for improved exhaust flow, a rear gear ratio between 3.55 and 4.10, and a torque converter with a stall speed around 2000 RPM. These components help the engine utilize the camshaft's powerband effectively.

Does this kit include everything needed for installation?

The kit comes with the camshaft, lifters, assembly lube, decals, and installation instructions. While these are the core components, you may need additional items like new valve springs, pushrods, or gaskets depending on the condition of your engine and specific installation procedures.

This specific grind is designed to wake up the mid-range powerband in your OE roller Small Block Chevrolet engine, while still offering a noticeable idle that lets everyone know you mean business.

To get the most out of this Xtreme 4x4 camshaft, you'll want to pair it with headers for better exhaust flow, and a rear gear ratio in the 3.55 to 4.10 range. A torque converter with a stall speed around 2000 RPM will also help you launch effectively off the line. This kit includes the camshaft, lifters, assembly lube, decals, and instructions, so you have the essential components to get the job done.

While it fits many applications, it's important to note that this camshaft is not CARB approved and cannot be shipped to California. Ensure your vehicle's emissions system meets local regulations before installation.
