1968 Hurst/Olds

During the second half of the Sixties, ever-growing big-block V-8 engines--and the tarmac-tearing torque they generated--were the hot ticket on the street. Yet while GM's A-body-based performance models were wildly popular, the corporation had imposed engine displacement limits of 400 cubic inches across the intermediate car line. Ford and Chrysler, meanwhile, knew what youth buyers wanted and proceeded to offer 428 Cobra Jets, 440 Magnums and even Hemis in their respective mid-size models, stripping market share away from GM. 

 

But thanks to one man's vision and a carefully coordinated venture that wound through some gray areas of the General's rule book during the summer of 1967, a GM intermediate coupe made it to market with a top-shelf 455... and more.
