This 1970 Ford Mustang Mach 1 has been heavily modified with a 5.4L/500 HP supercharged V-8 engine from a 2011 Shelby GT500, paired with a Tremec 600 6-speed manual transmission and a Currie 9-inch rear end. The car’s chassis has also been upgraded with TCI Mustang II independent front suspension, 3-link rear suspension, front and rear sway bars, coilovers, and Wilwood 4-wheel power disc brakes.

The interior has been swapped with a Shelby GT500, with a custom electrical system to power the drivetrain and amenities. The body retains its 1970s appearance with new sheet metal, bumpers, and floors, while the paint is Harley-Davidson Electric Orange with Hot Rod Black stripes and GT500 callouts.
