It was a golden era. Horsepower was unlimited; designers, builders, and drivers just needed to harness the horses of massive engines and deliver their thrust to the track. It was an age of 8-liter aluminum Chevys, turbocharged Oldsmobiles, flat-12 Porsches, and the best and brightest designers from McLaren, BRM, Lola, March, Shadow, AAR, Caldwell, Kar Kraft, and others who designed cars to suit them.
