What kind of idle can I expect with this camshaft?

This camshaft is designed for limited high-performance street use and will produce a mild, rough idle. This is a common characteristic of performance camshafts, especially on carbureted engines, and indicates the cam is working to improve engine breathing.

What supporting modifications are recommended for this camshaft?

For optimal performance, COMP Cams suggests pairing this camshaft with an aftermarket intake manifold, headers, a torque converter with a 2500+ RPM stall speed, and rear end gears in the 3.40 to 4.10 range. These modifications help the engine take full advantage of the camshaft's improved airflow.

Is this camshaft compatible with my California-registered vehicle?

No, this camshaft is not CARB approved and cannot be shipped to California. It is important to check local emissions regulations before purchasing and installing any aftermarket engine components.

Product Details

This is the COMP Cams C43 280H-R10 hydraulic roller camshaft, designed for Chevrolet 4.3L (262 cubic inch) V6 engines originally equipped with a flat tappet cam. If you're looking to get more out of your V6 for limited high-performance street use, this retro-fit roller cam is a solid option. It's built to work with a range of vehicles, including models like the Chevrolet Astro, S10 Blazer, and GMC Sonoma from the mid-80s through the late 90s.

This camshaft features a 224/224 degree duration at 0.050 inch lift and is intended for applications where you've already upgraded to an aftermarket intake, headers, and are running a torque converter with a 2500+ RPM stall speed, along with rear end gears in the 3.40 to 4.10 range. Expect a mild, rough idle with this cam, which is typical for performance camshafts on carbureted engines. The hydraulic roller design offers improved performance and durability over older flat tappet systems.

For optimal performance and to ensure proper operation, it's recommended to pair this camshaft with the appropriate supporting modifications. This includes a stall converter and gear ratio as mentioned, and it's important to note that this camshaft is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for detailed guidance on setup and break-in procedures.
