Shelby American started building high performance versions of the then new Ford Mustang in 1965. These featured modified 289 cubic inch, small blocks and uprated suspension. These were basically mildly disguised race cars. However by 1967, the times were changing and the buying public now wanted more boulevard racers rather than out-and-out street racers, as in prior years. They wanted style, comfort, power steering and brakes, even air conditioning over 'all-out' performance though they still wanted horsepower, so Ford introduced a new Mustang body for the 1967 model year. This new Mustang was more luxurious and larger overall with a wider engine compartment so it could hold a big block as well as the 289. Ford chose to put a 390 in their first big block Mustangs, but Shelby went with the 428 Police Interceptor.
The 1965 & 66 Shelby Mustangs closely resembled the stock Mustangs upon which they were based, so in an effort to distinguish the 1967 Shelby Mustang from the stock version, Shelby American made more body modifications including extending the front end by three inches. However, due to the cost of producing steel parts for a limited production car, Shelby American used fiberglass pieces for this task. The hood was fiberglass as well, with a built in functional hood scoop and two hood pins on either side whilst in the front grille, two 7 inch driving lights were mounted either side of the centre. At the rear end, a special cap was made to accommodate the 1967 Cougar tail lights and the rear spoiler. Non-functioning side scoops were added along with a new upper scoop to vent the cockpit. Mechanically, aside from the engine, the 1967 Shelby Mustangs were a lot closer to the stock GT Mustangs than the 1965-66 GT 350s. The cars came as GT Mustangs from Ford with Deluxe interiors. The stock suspension was retained with very few modifications except stiffer springs. However, the GT 500 introduced Ford's 428 Police Interceptor to the Shelby cars. Actually, this too was basically stock Ford except for the aluminum intake with two Holley 600 cfm 4 barrels. On top of the carbs was a finned, oval, COBRA air cleaner. Though it was officially rated at 355 hp, it was actually closer to 400.
For 1968, Shelby upped the ante, by fitting the 428 Cobra Jet engine. This featured greatly improved cylinder heads and exhaust manifolds. This led to the new suffix KR being appended to the GT 500. It stood for King of the Road, a title it backed up repeatedly both on the street and strip.
This stunning example has just completed a full, rotisserie restoration. It was built from an excellent 1968 Ford Mustang GT (the same basis as the real GT 500s). Every single part of the car was taken apart and rebuilt or replaced with new and the body and paint redone to concours standards in Ferrari Fly Yellow. The interior is exquisitely trimmed in the finest leather and the dash is signed by Carroll Shelby himself. All the glass, rubber and chrome are new. It is powered by a custom built, Shelby aluminium 427 FE Side oiler engine, which dynoed at 559 HP with 549 ft lbs of torque. The engine features every conceivable performance option available and cost over $27,000 to build. To get the power to the road, it has a custom built C6 automatic transmission, feeding a 9 inch Currie positraction rear end. In order to handle all this power, it has four-wheel power disc brakes and power-assisted, rack & pinion steering. The list of extras fitted to this car is enormous and the work performed, unparallelled. To say that it is an improvement in every way over the original, is a gargantuan understatement. It is surely one of the finest GT 500 re-creations ever assembled.
