When Ford rebooted the Shelby GT350, the company didn’t just put a different badge on existing engine. Instead, Ford Performance engineers went into the lab with the Coyote 5.0-liter and came out with a magical new powerplant — the 5.2-liter Voodoo engine. At the time, it was the longest stroke flat-plane crankshaft engine produced.

Designed to delivery the fat midrange and scintillating rev range that a road-course-oriented Mustang needs. With 526 horsepower on tap and an 8,200-RPM redline, the Voodoo engine is a potent performer right off the dealer lot. However, we enthusiasts are never satisfied with stock, so if you want to push your 5.2-liter engine with more RPM or by strapping on a power adder, Ferrea Racing Components has the valvetrain upgrades to ensure that it howls for many moons into the future.

If you want to push your Voodoo 5.2-liter engine harder than Ford Performance engineers ever intended, Ferrea has the valvetrain upgrade for you in the form of its Ford Voodoo 5.2-liter 2015-2017 (GT350) Dual Spring kit (PN KT4032; $2500.80).
