What kind of idle can I expect with this camshaft?

To maximize performance, it's recommended to pair this camshaft with an engine that has at least 9:1 compression, a torque converter with a 2800+ RPM stall speed, headers, and appropriate rear-end gearing. You will also need to follow the manufacturer's installation instructions.

Is this camshaft compatible with my 1975 Oldsmobile Delta 88?

Product Details

This COMP Cams Xtreme Energy camshaft is designed for Oldsmobile 260 through 455 cubic inch V8 engines, specifically for street and strip applications. You'll get the camshaft itself, ready to be installed in your engine. It's built to offer a noticeable bump in performance over stock, but it comes with a rougher idle and requires some supporting modifications to really shine.

To get the most out of this camshaft, you'll want to ensure your engine has at least 9:1 compression. It also pairs well with a higher stall torque converter (2800+ RPM), headers, and appropriate rear-end gearing. These components work together to help the camshaft breathe better and make more power, especially at higher RPMs. It's a well-built piece from COMP Cams, known for their performance valvetrain components.

This camshaft is intended for enthusiasts looking to wake up their Oldsmobile V8 for weekend fun. Keep in mind that due to its aggressive nature, it's not recommended for daily drivers where a smooth idle is a priority. It fits a wide range of vehicles, including models like the Oldsmobile Cutlass Supreme, Delta 88, and Buick Electra, among many others from 1967 onwards.
