While Gary knew his Mustang would be fast with the new engine, he also wanted it to handle well too. The front suspension was completely changed out for a tubular A-arm design with coilovers, while the rear suspension retained its leaf spring setup. Next, a rack-and-pinion steering system from a Mustang II was installed, and Wilwood 12-inch brakes with drilled and slotted rotors were added, both front and rear, to provide sufficient stopping power. Finally, Gary had Performance Restoration Services fit a set of sticky Goodyear Eagle F1 tires over the American Racing Torque Thrust II wheels.

While various aspects of restoring the car offered up different types of challenges, the biggest obstacle by far was the engine. "By far the engine build was the hardest part," Gary says. "Production was very limited, so finding parts or even someone who knew anything about them was difficult." He turned to Butch Engelbrecht of B.E. Motorsports in San Diego. Engelbrecht was able to correct some problems created by previous work done to the engine and was able to locate some hard-to-find parts. He was also able to provide less aggressive custom Crane camshafts so that Gary could more easily drive the Mustang on the street.

With all the parts he needed in his possession and the engine ready for assembly, Gary then took the Cammer over to QMP Engines in Chatsworth for the final blueprinting and build. Both the bore and stroke were increased to 4.26 inches and 4.25 inches respectively, yielding a total displacement of 484 cubic inches. QMP fitted the V-8 with H-beam connecting rods, JE forged pistons with a 10.5:1 compression, and T&D roller rocker arms. The engine also features dual Holley 650 carburetors, Mallory fuel pumps, a CSR electric water pump, a custom Ron Davis aluminum radiator, and an MSD Pro-Billet distributor. On the exhaust side are full-length thermal-coated headers and Flowmaster mufflers. In total, when Gary's Mustang is strapped to the dyno, the SOHC 427 puts out a healthy 538 rwhp and 560 rwtq.

While some people have told Gary they think he should restore his Mustang to its original condition, he likes it just the ways it is. "I wanted something that would be unique, and this sure does turns heads," he says. At the time that we photographed the car, he hadn't taken it to any car shows, but he definitely plans to in the future. And would he ever consider selling his Mustang? Not a chance.
