The COMP Cams B455 XE274H-10 Xtreme Energy hydraulic cam targets midrange power for Buick 400, 430 and 455 engines. It delivers stronger midband torque but benefits from supporting modifications such as headers and a 2200-stall torque converter to realize its potential. This cam is intended for builders seeking a noticeable step in midrange performance when paired with compatible hardware.
