COMP Cams Camshaft H8 XE284H

COMP Cams is a well-known name for performance valvetrain parts, and this XE284H camshaft is a solid option for Holden V8 owners looking to get more out of their engines. This is a hydraulic flat tappet camshaft designed for street and strip applications, meaning it's built to handle both daily driving and occasional track use. It's specifically intended for Holden 252 to 308 cubic inch V8 engines from 1970 through 1988.

The XE284H features a 240-degree intake duration and 246-degree exhaust duration, which is a notable step up from stock and contributes to its aggressive performance profile. COMP Cams recommends a stall speed of 2800 RPM or higher for this camshaft, and it really likes to be paired with headers and appropriate gearing to make the most of its capabilities. Be aware that this camshaft will result in a rougher idle compared to a stock camshaft, which is typical for performance grinds like this.

When installing this camshaft, remember it's not CARB approved and cannot be shipped to California. It's a good idea to have a fresh set of lifters and potentially valve springs to match the camshaft's specifications for optimal performance and reliability.
