Overview
The GT/FX shows what a Coyote swap looks like when the shop upgrades every other part to match. Fat Fender Garage, a custom truck builder in Gilbert, Arizona, revealed the 1956 Ford F-100 on November 3 for SEMA 2026. Notably, the builder reports more than 15,000 hours of design, engineering and fabrication.
Power comes from a Gen 3 Ford 5.0-liter Coyote V8 topped with a 3.0-liter Whipple supercharger. According to the release, the engine makes 800 horsepower and 750 pound-feet of torque. Then Ford’s 10R80 10-speed automatic sends the output to the rear wheels.
No price has been announced. The builder frames the truck as a showcase, including its chassis, interior and FF Performance Parts line. For another Ford truck with a Coyote under the hood, read about the twin-turbo Coyote Maverick. Our SEMA 2026 guide for truck owners also shows where this reveal fits.

What the Coyote Swap Delivers Under the Hood
The Coyote swap makes 800 horsepower because Fat Fender Garage added a 3.0-liter Whipple supercharger to a Gen 3 5.0-liter V8. Torque measures 750 pound-feet, according to both the builder and Car and Driver. Ford’s 10R80 also handles the shifting.
The exhaust matches the output. For example, the shop built a three-inch system with Borla XR-1 Raceline mufflers, JMD resonators and electric cutouts. In addition, custom valve covers dress up the engine bay.
One detail needs a flag. Meguiar’s lists the truck at 725 horsepower in its SEMA booth release. However, the builder, Car and Driver, Motor1 and Carscoops all report 800 hp, so this article uses 800.
Chassis, Brakes and Tires Support the Coyote Swap
The F-100 rides on the FF1 Performance Coilover Chassis instead of the original frame. According to the shop, the chassis and suspension prioritize body control, sharp cornering response and stability under acceleration and braking. To me, this chassis is the real headline.
Car and Driver lists Wilwood disc brakes for stopping power. Six-piston calipers sit up front, and four-piston calipers sit at the rear. HRE wheels also carry Toyo Proxes Sport 2 tires, measuring 315/35R-20 at the rear.
The tire size tells you the truck’s purpose. A 35-series sidewall suits pavement, not rocks. The Shelby two-door F-150 also trades trail ability for road speed.
Body and Cabin Changes
Fat Fender Garage gave the body the same attention as the chassis. First, the shop fabricated the all-steel body by hand. Fat Fender Garage pancaked the roof and hood, sectioned the cab by two inches and widened the front and rear fenders. A grafted-in GT350 rear diffuser and chin splitters also add a track-day look.
Per the builder, the factory grille is the only major exterior piece left unmodified. For me, leaving it alone is the smartest choice on the truck, because the F-100 stays recognizable. Behind the cab, the bed also gets flared double walls and a tailgate with a push-button drop.
Inside, the shop fitted a black interior with custom-upholstered bucket seats and a leather dash pad. A concealed climate-control system also pushes air through one hidden vent. Modern gauges, audio and door actuators then complete the cabin.
What This Means for You
If you own a classic Ford truck, the GT/FX shows where the work goes. First, treat a Coyote swap as a whole-truck project. The builder paired the engine with a new chassis, six-piston front brakes, a 10-speed and a three-inch exhaust. However, a 15,000-hour show build sets the ceiling, not the minimum, for your truck.
Planning a smaller swap of your own? Start your shop-gear list with an engine hoist, a load leveler, jack stands and a torque wrench. Every swap begins with the old engine coming out, so those tools come first. Next, price the brakes and the transmission before you buy the engine.
This kit suits a home garage. A load leveler comes with the Goplus 2 Ton Folding Engine Lift. TONDA Jack Stands 3 Ton arrive as one pair. EPAuto 1/2-inch Drive Click Torque Wrench covers 10 to 150 ft/lb. Read the Goplus hoist reviews first, because it rates 4.0 stars against 4.6 for the stands and the wrench.
Shop gear for an engine swap
If you want a classic Ford for the trail, this build is the wrong template. None of the four reports mentions off-road use. The 315/35R-20 rear tires also point to pavement.
Final Thoughts
As a show truck, the GT/FX earns the attention. However, a Coyote swap alone does not make a 1956 F-100 interesting. Instead, the new chassis, the brakes and the hand-built body make 800 hp believable.
I do not call it a trail truck, and I do not think it needs to be. Fast cars were my passion before off-roading took priority, so I still enjoy watching a shop treat an old Ford like a supercar project.
Fat Fender Garage has not announced a price. Until it does, use this build as a checklist for a serious swap. Then enjoy it for what it is, a supercharged classic Ford.

Is the GT/FX an off-road truck?
No source describes it as one. Instead, the builder pitches supercar-style handling, and the rear tires measure 315/35R-20. Treat it as a road truck and a show truck.
