This GTO made its competition debut in the Paris 1000 Km and raced to overall victory by brothers Pedro and Ricardo Rodriguez at the record speed of 98.015 mph that stood until 1968. Roger Penske raced it to victory in the five-lap Nassau Tourist Trophy 'preliminary' and the 25-lap Nassau Tourist Trophy on December 2nd leading a four-car GTO sweep. Penske raced it again in the three-hour 1963 Daytona Continental in John Mecom's distinctive blue and white American racing colors scoring second overall to the GTO of Pedro Rodriguez. Penske and Augie Pabst raced it to fourth overall and first in the three-liter GT class in the 1963 12 Hours of Sebring Two months later Penske raced to yet another checkered flag in the Pensacola SCCA races. Ex-Ferrari factory F1 racer Richie Ginther took it to fifth overall in the 1963 LA Times GP at Riverside that fall and repeated the feat a year later in the 1964 Times GP at Riverside. A decade after its introduction this massively credentialed GTO was still competing at the top of the field with owner Claudio Zampolli placing fourth in the Ferrari Owners Club hillclimb.
