The Ford Mustang grew a size for the 1967 model year. Also the car became more powerful with a 390 cid (6.4 litre) big-block option, which boasted some 320 hp, considerably more than the racy Shelby GT-350 had to offer. The power-output of the 1967 GT-350 even was reduced from 306 to 290 hp to comply to noise restriction regulations.
But Shelby overclassed the 390 cid Mustang with a new model: the GT-500. In the GT-500 Ford's new 428 cid V8 was fitted, a massive 7-litre unit producing a staggering 400 hp @ 5600 rpm. For insurance reasons however a moderate 355 hp was advertised.Home
