World-famous custom car builder and high-quality billet parts manufacturer Ringbrothers unveiled its newest, one-of-a-kind Ford Mustang, the 1969 Mach 1 known as “UNKL” in the Flowmaster (Holley) booth at the 2019 SEMA Show. “UNKL” is the first Mach 1 to leave the Spring Green, Wisconsin, shop after a series of memorable Mustang builds. The widened body and unique race-inspired theme make the most of road and race technology in one car. “UNKL” is powered by a 520-cubic-inch Jon Kaase Boss engine making 700 horsepower. A reworked Bowler six-speed Tremec transmission backs the high-powered engine, and a QA1 carbon-fiber driveshaft transfers power to the rear wheels. The Mach 1’s growl comes from a custom stainless-steel Flowmaster exhaust. Prestone coolant keeps the engine at an even operating temperature, while Motul engine oil and gear oil keeps things running smoothly. Custom BASF paint called Big Boss Blue has been laid over a smooth body, which was shaped with 3M products. Ringbrothers extended the Mach 1’s body by an inch on each side, which gives it a slightly more aggressive stance than stock without compromising the classic look. The car’s body is a mixture of carbon-fiber and steel panels reshaped by Ringbrothers. Other custom details include billet taillights, reshaped bumpers and trim and engine-bay accessories that were custom machined at the Ringbrothers facility.
UNKL will be handed over to the owner who plans to race the car hard and often. This is not a show pony, its a race car, through and through. The build was done with performance as a top priority and styled with the classic Ringbrothers flare.
