Aloophole in racing regulations allowed Porsche and Ferrari prototypes (the Porsche 917 and the Ferrari 512) to race with 5-liter engines in a class technically designed for less potent, higher production volume sports cars. In 1971, the Porsche 917 was closing in on 240 mph at the end of the Mulsanne Straight at Le Mans. In an effort to rein in speeds, the rules changed yet again for 1972, limiting prototypes to 3 liters and mandating a weight of 1,433 pounds. Ferrari’s challenger for the 1972 World Sportscar Championship was this car, the Ferrari 312 PB, which won 10 of 11 races that season (it was not entered at Le Mans). A key ingredient in the 312 PB’s success was its Formula 1 derived 3- liter V-12 engine, which produced 450 horsepower at 10,800 rpm. This particular 312 PB was raced by Jacky Ickx, the featured driver at the Amelia Island Concours this year.
