cars: After 2 years of its 3-year program, Ford had very little to show for its immense investment. Extensive work was done in the wind tunnel, and improving the brakes, handling and engine – not least improving the fuel economy. The 7-litre Ford NASCAR race engine now put out ca. 550 bhp but was registered as "485 hp" as a result of Ford's lowered rev-limit setting for the 24h race. The new year started with promise with Ken Miles and Lloyd Ruby winning both the inaugural 24 Hours of Daytona and then 12 Hours of Sebring. Copying Ferrari's tactic of overwhelming numbers, they put in fifteen Mark II entries; eight were accepted by the ACO. This time six were built and prepared by Holman & Moody. Shelby ran three cars for Americans Dan Gurney and Jerry Grant, Miles was now paired with New Zealander Denny Hulme after Ruby had been injured in a plane crash a month earlier. The third car was the all-Kiwi pairing of Bruce McLaren and Chris Amon. Holman & Moody, the successful Ford NASCAR race team also brought another trio of GT40`s as backups, – for Mark Donohue/Paul Hawkins, Ronnie Bucknum/Dick Hutcherson, and Lucien Bianchi/Mario Andretti. One of the big improvements Holman & Moody brought with them was a quick-change brake pad system to save time in the pits. The British team Alan Mann Racing had two cars prepared by Ford Advanced Vehicles, for Graham Hill/Dick Thompson and John Whitmore/Frank Gardner. Each of the eight cars was painted in a colour from the Mustang road-car range. Ferrari's response to the Mk II was the new Ferrari 330 P3. Shorter and wider than the P2, it kept the same 4-litre engine but with fuel-injection now put out 420 bhp. The works team had a pair of closed-cockpit versions for John Surtees/Ludovico Scarfiotti and former winners Lorenzo Bandini/Jean Guichet. An open-cockpit variant was given to the North American Racing Team (NART) for Pedro Rodriguez/Richie Ginther. But their race preparation had been limited by strike action in Italy. NART also entered a long-tailed P2, rebodied by Piero Drogo and driven by last year's winner Masten Gregory with Bob Bondurant. There were also P2/P3 hybrids for the Ecurie Francorchamps (Dumay/"Beurlys") and Scuderia Filipinetti (Mairesse/Müller. Finally there was a P2 Spyder for Maranello Concessionaires (Attwood/Piper). Fighting on two fronts, the company also took on Porsche in the 2-litre class with its
