Jack Roush

Jack Roush, the creator of the Roush Mustangs and the originator of Roush racing, began his career in 1964, as an engineer at Ford Motor Company. At the same time, like the rest of America, his love for the new Mustang included the purchase of his first Mustang in 1965.

Roush's interests led him to racing and a profession as a drag racer. But his love of racing led him to other endeavors, including SCCA Trans AM, IMSA and NASCAR.

Like another Mustang icon, Carroll Shelby, Roush was also a strong businessman, using his educational background and engineering expertise to found his own company, Jack Roush Performance Engineering in 1976, which led ultimately to the current Roush Industries.

Roush Racing

But it was his other company, Roush Racing, which he started in the late 80's that made headlines throughout professional auto racing. SOme of the big names associated with Roush Racing include Matt Kenseth, Mark Martin and Carl Edwards.

The Roush Ford Mustang was born of Jack's love of racing, hot rods and his personal love of the Mustang.

What made it all work, was his OEM expertise, engineering and manufacturing capabilities, combined with his deep knowledge of how to make any kind of race car go fast.

Roush Mustangs - Not Just Another Tuner Car

Unlike many other "tuner" Mustangs where a body kit seems to be most of the modifications, or perhaps engine performance enhancements,with some body mods, the Roush Mustangs were created to blend performance, handling and looks into one slick package.Nonetheless, his early cars were sometimes criticized for not having enough power to follow his other improvements.

The Roush Mustang became a fixture in the racing world in early 1987, beginning in several Grand Touring forms and Roush wasn't slow in pitching the powers that be at Ford, on the idea of mass produced Roush Mustangs, which could be offered throug Ford's dealer network. While interested, Ford declined his first offer.

A Roush Pony Car For The Streets

But that was not the end of the Roush Mustangs, and in 1994, the First generation of Ford Mustang based cars hit the streets. The cars were offered in Three Stages.

Stage l was strictly an appearance package, consisting of body add ons.

Stage ll added a race proven suspension package, which pushed Mustang skidpad numbers into areas most pony car enthusiasts had never seen before. Pieces included Hyperco coil springs, Roush/Koni double adjustable struts and shocks,30mm front and 27mm rear sway bars.

Stage lll included hot rod techniques and parts from the Ford Racing bin to bump up power from the stock GT by almost 50 horsepower.

Roush Performance Products

Not one to sit still, Jack created ROUSH Performance Products in 1995 to produce and sell aftermarket performance parts, including performance crate engines.

Some of these high performance parts included iron and aluminum CNC ported GT40 heads for both 5.0 and 5.8 liter engines. Aluminum heads get larger Manley 1.94 intakes as well as Roush CNC ported Trick Flow heads for big blocks.

Suspension bits included panhard bars for sn95 mustang, traction bars,and handling packages.

What made these packages unique, was the level of engineering that went into making the packages fit together into one well thought out and sorted out car.

One of the unique things you'll see in the early cars, is the unique ram's horn looking air boxes atop the engines, fed through the 3 piece fiberglass hood assembly. Prices at the time were:
