The new rev-happy 5.2-liter V-8 in the Mustang Shelby GT350 is one of the most compelling reasons to visit a Ford dealership in 2016. Code-named Voodoo and sharing its basic architecture with the Mustang GT’s 435-hp, 5.0-liter Coyote engine, this new powerplant is an altogether wilder animal, producing 526 horsepower at 7500 rpm and 429 lb-ft of torque at 4750. Fittingly, Ford’s Voodoo V-8 assembly begins with the car’s most-hyped part, the flat-plane crank, which helps allow for the higher engine speeds—and a wicked yowl—that set the GT350 apart from lesser 'stangs.
