When the '96 Mustang came out with the 4.6-liter V-8, some performance enthusiasts were scared away by its technology. But those days are long gone. Ford added horsepower and torque to its 2- and 4-valve V-8s over the years, and the number and quality of available aftermarket performance parts has exploded. Ford took things to the next level with the new 3-valve Mustang GT engine and the 5.4-liter GT and Shelby GT500, adding even more high-performance options.

In this updated edition of How To Build Max-Performance 4.6-Liter Ford Engines, Sean Hyland gives you a comprehensive guide to building and modifying Ford's 2-, 3-, and 4-valve 4.6- and 5.4-liter engines. You will learn everything from block selection and crankshaft prep, to cylinder head and intake manifold modifications. He also outlines eight recommended power packages and provides you with a step-by-step buildup of a naturally aspirated 405-horsepower Cobra engine. This is the definitive guide to getting the most from your 4.6- and 5.4-liter Ford.
