1994 Ford Boss Concept Mustang

This 1994 Mustang is not one you can buy—in fact, it is a concept car. It was built by SVE (Special Vehicle Engineering—Ford Motor Co.) as the right car to challenge a 572 c.i. Chevrolet ZL-1 Camaro. Which car is the fastest? The drag race took place in January, 2000—but without definitive results. Oh well, it still makes for interesting reading!

The Boss Mustang was the brainchild of John Coletti, the Chief Engineer of SVE at the time, while Jon Moss headed Special Vehicles for all of GM. By October 1999 both finally agreed to a match race—two rounds, with one at the drag strip and the other on a road course—with the 1994 Boss Mustang for Ford and the 1999 ZL-1 Camaro for GM. They would both have mufflers, but both will be allowed to use race fuel and whatever tires would fit the stock-looking wheels

If Chevrolet could use an aluminum block 427 bored and stroked to 572 cubic inches, so could Coletti use the 429 cubic inch Boss 429 semi-hemi. The block and heads were from the Ford catalog which made for a big, really big version of the 429—610 cubic inches!

The engine used in the Mustang had a racing factory aluminum block with Boss 429 heads. The intake system used fuel injection; with a bore and stroke of 4.8/4.5 in. and a 10.5 :1 compression ratio, resulted in 610 cubic inches.

The Mustang made 855 horsepower, 790 lb.-ft. toque, and it ran 0-60 in 1.9 seconds, 0-100 in 5.5 seconds, and the quarter-mile in 10.55 seconds @135.05 mph. The transmission was a C6 three-speed automatic with a 3.70:1 final drive ratio. The front tires were BFGoodrich g-Force KD 275/40ZR17 with the rear tires being BFGoodrich Drag Radial 315/35ZR17. Front and rear brakes were Brembo and wheels were 17x8.0 and 17x10.5 in. rear.

The Mustang did better than the Camaro in the drag race part—10.55 to 11.01 secs; in the road race course, the Camaro succumbed to oil pressure loss.

My son was lucky to be photographed with the Boss, and the car definitely sounded like it had a cam. Its sound was low and guttural. It’s a car that demands, and gets, respect.
