Ford is soon to unveil an all-electric crossover inspired by the Mustang and expected to be called the Mach E. This is most emphatically not it. But for some, at least, it's even better.

Called "UNKL," this 1969 Ford Mustang Mach 1 was unveiled at SEMA this year, boasting a series of upgrades from the experts at Ringbrothers. And as you might have guessed, that starts under the hood, where the Wisconsin-based tuner has shoehorned in a truly massive engine: the Jon Kaase Boss V8 displaces a gargantuan 520 cubic inches – that's 8.5 liters – and kicks out 700 horsepower.

All that muscle is transmitted to the rear wheels through a six-speed Tremec gearbox reworked by Bowler and a QA1 carbon-fiber driveshaft. The huge-block engine breaths out through a custom stainless-steel exhaust by Flowmaster (at whose booth the vehicle was displayed).

It all rides on an Aluma-Frame front and QuadraLink rear suspension by Detroit Speed Engineering, with tubular arms, adjustable RideTech coilover shocks, a cast aluminum cradle, and a custom steering rack. And it rolls on HRE forged alloys measuring 19 inches up front and 20 at the back, shod in Michelin Pilot Sport 4S tires and packing Baer brakes.

The wide body was custom fabricated to add an inch on each side, with body panels recrafted out of steel and carbon fiber, and billet aluminum accessories trading on Ringbrothers' speciality. It's all coated in a special BASF paint called Big Boss Blue with a race-inspired livery. And the interior is fitted with Recaro seats, more billet aluminum trim, Ididit steering column, Classic Instruments guages, and a Vintage Air climate-control system.

It's a heck of a build, and a suitable tribute to the uncle that was the company owner's early inspiration in developing an evident love for muscle cars.
