The Buick 400-455 Hi Energy Hyd Cam - 252H10 by COMP CAMS is designed for classic muscle car builders and restoration specialists aiming to enhance performance in big-block Buick engines. This hydraulic roller cam is tailored to deliver aggressive valve timing and lift characteristics, setting it apart from stock engine configurations.
