COMP Cams Camshaft B455 XE274H-10

If you're looking to get more mid-range power out of your Buick 400, 430, or 455 V8, this COMP Cams Xtreme Energy camshaft is a solid option. It's designed to wake up the engine in that crucial RPM range where you spend a lot of time driving. This camshaft fits a wide variety of Buick models from the late 60s through the mid-70s, including popular cars like the Electra, LeSabre, and Riviera, as well as performance models like the GS 400 and GS 455.

This is a hydraulic flat tappet camshaft, meaning it uses standard lifters and oiling systems, making installation more straightforward than some other types. The XE274H-10 grind offers a good balance for street use, providing a noticeable improvement in acceleration and pulling power without being overly aggressive. To really take advantage of what this cam has to offer, you'll want to pair it with a good set of headers and a torque converter with at least a 2200 RPM stall speed. This setup will help the engine breathe better and keep it in its power band.

When installing this camshaft, remember that it's not CARB approved and cannot be shipped to California. Ensure you have the necessary supporting modifications, like headers and the appropriate torque converter, to get the most out of this well-built camshaft.
