Product Details

If you're building a Pontiac for bracket racing, especially a heavier car, this COMP Cams P8 276Ah-10 hydraulic camshaft is a solid option. It's designed to work well with a 2500-3000 RPM stall torque converter and requires at least 9.5:1 compression and a good amount of rear gear to perform at its best. You can expect a noticeable, choppy idle with this cam, which is characteristic of performance camshafts built for this type of application.

This camshaft is built for performance, offering an updated profile that works with a wide range of Pontiac V8 engines, from the 265 to the 455 cubic inch displacement. Its hydraulic lifter design means you don't need to worry about the maintenance associated with solid lifters, making it a practical choice for a dedicated race car. The 228/236 degree intake/exhaust duration at .050 lift is a popular choice for achieving strong mid-range power crucial for consistent bracket racing runs.

When installing this camshaft, ensure you have the necessary supporting modifications like the appropriate stall converter and rear-end gearing to match its aggressive nature. This cam is intended for off-road use and is not CARB approved, so it cannot be shipped to California.
