The upgrade is available only on 2018-2019 F-150s equipped with the 5.0-liter V8, which normally does 395 hp and 400 pound-feet of torque. But Hennessey adds a 2.9-liter supercharger and other tweaks, including increased boost pressure, and air-to-water intercooler and a fuel-injector upgrade, that takes power to 768 hp at 7,000 rpm, making it more powerful than the Ford GT.
Other features include stainless steel cat-back exhaust, a dyno-tuned chassis and Hennessey Performance Engineering engine management calibration. You also get serial-numbered dash and engine plaques, Hennessey exterior badges and embroidery on the headrests.
There’s also a choice of sport kit or off-road upgrades. The former comes with a lowering kit, sway bars, Brembo brake system and 22-inch wheels with tires. Off-road upgrades include Hennessey front and rear bumpers with five LED lights embedded in the front ones, 20-inch 10-spoke wheels, 35-inch off-road tires and a front suspension leveling kit for an overall lift of 3 inches.
There’s no word on pricing; Autoblog has sought comment from Hennessey.
As shown in the video above, the Hennessey Ford Heritage squad now includes red-and-white livery versions of the F-150, Mustang, 2005 GT and the 2017 GT.
