The COMP Cams XE256Ph camshaft set for Ford 4.6/5.4L Modular 3V is a powerful upgrade over stock with a pleasing idle and improved low-end torque combined with a strong midrange. It uses hydraulic roller finger followers and calls for spring and phaser modifications. Custom tuning is required; stock gears and converter are acceptable for many installations.
