What kind of idle can I expect with this camshaft?

This COMP Cams camshaft is designed for performance and will produce a rougher idle compared to a stock camshaft. It's best suited for street machines where a noticeable idle is acceptable.

What other modifications are recommended when installing this camshaft?

For optimal performance, it is recommended to use headers and lower rear-end gears with this camshaft. A torque converter with a 2200+ stall speed is also suggested for street machine applications.

Does this camshaft come with lifters?

Yes, this is a hydraulic camshaft, meaning it includes hydraulic lifters. These lifters do not require manual adjustment like solid lifters, making them more convenient for street use.

Product Details

This COMP Cams Magnum camshaft features a 230/230 degree duration at 0.050 inch lift, making it a solid choice for street machines that have been upgraded with a 2200+ stall torque converter. It's designed for Oldsmobile 260 through 455 cubic inch V8 engines, covering a wide range of applications from 1967 and newer, including popular models like the Oldsmobile Cutlass Supreme and Delta 88.

Because this camshaft has a rougher idle and is intended for higher RPM use, it pairs well with headers and lower rear-end gears to help you get the most out of its performance profile. The hydraulic lifter design means you won't need to adjust valve lash as often as with a solid lifter cam, offering a good balance of performance and streetability for modified vehicles.

When installing this camshaft, remember that it's designed for use with headers and a higher stall speed torque converter. It's important to check the manufacturer's installation instructions for any specific break-in procedures or other requirements to ensure optimal performance and longevity.
