While Paul's Mustang is a full-blown race car, he wanted to keep the look of a street-driven car. "Even though it is a race car, when people look at it I don't want them to think it's a race car," he tells us. Regardless, much of the body panels have been changed out for lighter components. The carbon-fiber, 4-inch cowl hood and trunklid save several pounds over the factory panels, as do the JPC front and rear bumper supports that replace the stock crash guards.

Inside the same theme continues. The 10-point, 8.50-certified rollcage and Kirkey race seat give away the car's true purpose, but Paul kept the factory dash and door panels to maintain a street-car look. Even so, he still managed to take plenty of weight out of the car. All of the mechanicals, including the power windows, were removed from behind the door panels and any unnecessary wiring was removed from behind the dash. The rest of the interior features an MMR rear seat-delete kit, Momo Race 3000 steering wheel, Auto Meter gauges in the center stack, and an Auto Meter 5-inch tachometer and shift light mounted on the dash.

Paul finally completed his car, constructed almost entirely by himself in his driveway, and took it out to the track in August 2011, a little more than one and a half years after he first started the project.

"I was a little scared at first because I didn't know what to expect," he remembers. Paul had nothing to worry about, though, as his new Mustang proved to be even faster than his previous one, running consistent 9.4s in the quarter-mile. Paul expects the car to run further, though, as he has yet to make a pass with the recently installed nitrous system engaged. His goal is 8.70 in the quarter and 5.50 in the eighth. He'll have plenty of opportunities to practice, though, as he races in PSCA and Street Car Super Nationals events regularly.

Paul would like to thank the many vendors that made his big-block S197 Mustang happen, as well as the members over at www.S197forum.com, who didn't shun him when he stepped away from the Ford modular motor.

You can see more details about the build and the parts used at his website, www.Psfracer.com.

Horse Sense: After a near-death accident that totaled his '05 Mustang, Paul Fercho decided that he wasn't going to wait any longer to build his dream car. By combining a big-block V-8 with the S197 platform, he built his ultimate Mustang that takes old-school horsepower and blends it with new-school looks.

You might think that a big-block V-8 wouldn’t fit in the S197 Mustang’s engine bay, but it’s the same width and just 2.5 inches longer than the Three-Valve 4.6-liter V-8. No fabrication was needed, and a set of custom engine mounts and a custom transmission mount were the only items required for the install.
