Adam Kuffel purchased his '85 Mustang in 1993. It was totally stock with a charcoal gray interior and approximately 140,000 miles on the motor. The car was meant to be cheap transportation during Adam's college years when he was enrolled in Southern Illinois University's Automotive Technology program.
It didn't take long, however, for the Mustang to become a major source of weekend fun, racing at the local dragstrip. One of the first changes Adam made was to paint the car a bright Corvette yellow in his driveway. The university training paid off because his first attempt at an a paint job turned out quite well.
A few years later, Adam pulled the 302 for the first time, even though the 185,000-mile engine was still running smoothly. Working after class at Step Up Performance in Roselle, Illinois, he accomplished the majority of machining required to bring the 302 back into spec. The block was bored 0.030-over and Manley flat-top pistons were installed, along with a Ford Racing "B" cam and World Products Windsor heads, milled to 52 cc for higher compression. A Holley 600 double-pumper carb, an Edelbrock Performer intake, a Mallory fuel pump, and BBK headers transformed the lightweight Stang into a strong daily driver during the week and one that ran in the high-12s on the weekends.
Adam's first job after college was working for Chevrolet Technical Assistance in Detroit, where the newest man on the team got picked on daily for driving a bright yellow Mustang to the Chevrolet building. (This is where the "General Motors Nightmare" license plate originated.) Of course, the Camaro SS and Corvette owners found new respect for Adam when he easily pulled away from them in his home-built special. We're not sure if Adam changed jobs to accommodate the Mustang, but he soon found employment at the Ford Technical hotline, in which parking lot both car and owner felt right at home. Unfortunately, with 240,000 miles on the speedometer, the Mustang was in need of a major refurbishing.
Adam did the work himself, stripping the body and replacing the doors and hatch with parts from a '93 GT. With the motor removed, he smoothed the engine compartment, filling all the excess holes on the firewall and inner fender panels. It was also the perfect time to install the eight-point rollbar that stiffened the chassis and added safety on the strip. Moser C-clip eliminators were added along with HPM Double Cross subframe connectors.
An 8.8 rear from a '92 GT was fitted with 31-spline Mosier axles, a Strange spool, and Motorsport 4.10 gears, controlled by Lakewood 50/50 shocks. A right-side airbag was added to counteract engine torque. Up front, 90/10 Lakewood shocks and four cylinder springs ensured proper weight transfer off the line. Weld 15x3 Drag Light wheels and 26x7.5 M/T Sportsman rubber did the steering, while fat 15x8 versions in the rear with 28x12.5 M/T ET Street tires handled traction.
Once the powertrain was complete, all the body panels were smoothed, emblems were shaved, and a few custom touches were added, like '79 Mercury Capri taillights, a '93 GT wing, '86 SVO sail panels, and an '83 Mustang GT hood. The wheel openings were rolled to make room for the larger tires, while the inner tubs were massaged, a task Adam accomplished with a large hammer. He chose the same shade of bright Corvette yellow, but this time he sprayed a DuPont basecoat/clearcoat combo.
There are enough subtle changes...
There are enough subtle changes on this bright yellow Mustang to convince you not to mess with it. Big 'n' little rubber, a rollcage menacingly visible through the window, a fuel-pressure gauge mounted prominently on the hood, and a not-so-subtle exhaust note mean a poorly timed challenge just might jeopardize your pink slip.
The detailed 306 is painted...
The detailed 306 is painted with three coats of Porsche Red paint. March underdrive pulleys increase horsepower, and March engine brackets allow a serpentine belt. Brightwork in the all-business engine compartment is provided by the Summit Racing valve covers and the original '85 Mustang GT air cleaner that directs twin streams of cold air to the engine from the original driving light openings, using owner-fabricated duct work.
