Tavoni and his lieutenants. Into this void stepped young engineer Mauro Forghieri and long-time racing bodyman Sergio Scaglietti, founder of Carrozzeria Scaglietti. Forghieri successfully honed the GTO's handling and Scaglietti designed an all-new body for the car. The GTO went to the 1962 12 Hours of Sebring with drivers Phil Hill and Olivier Gendebien. They placed first in class and were second overall behind the Ferrari 250 Testa Rossa. It continued winning through 1962, brushing aside the challenge from Jaguar and becoming one of the most famous sports cars in history. This shakeup, and Forghieri's engineering talent, made the 1960s even more successful for Ferrari than the previous decade. The mid-engined Dino racers laid the foundation for Forghieri's dominant 250-powered 250 P. On the street, the Dino road cars sold strongly, and legendary models like the 275 and Daytona were on the way. 1963–1967 – The United States rivals The big V8-powered AC Cobra (Shelby Cobra) challenged the Ferraris in the early 1960s. By 1963, Ford tried to buy Ferrari but no agreement was reached. Instead, the Ford GT40 ended the dominance of Ferrari P (the P standing for prototype) at the 24 Hours of Le Mans in 1966 when GT-40 Mark IIs finished 1-2-3. Ford dominated Le Mans again in 1967 in the Mark IV. 1968 – Ferrari boycott After the performance of the big V8-powered Ford at the 1967 Le Mans, the Fédération Internationale de l'Automobile (FIA) banned prototypes over 3000cc, which also affected the 330Ps. The change was announced in late 1967 and came in effect for 1968; for that season, the Scuderia did not take part in sports car racing in protest. 1969–1971 – The challenge with Porsche These years saw a new challenger. Formerly competing with smaller cars only, the Germans entered the new 3-litre sports car prototype class in 1968 with the Porsche 908, while Ferrari raced the Ferrari 312 P in only few events in 1969. In March, the presentation of the 5 litre Porsche 917, built in advance in 25 exemplars, had surprised also Ferrari, which answered later that year with the production of 25 Ferrari 512S, funded from the money gained by the Fiat deal. At that time, Porsche had almost a full season of experience with their new car, and took the World Sportscar Championship where Ferrari was only 4th. The 1970 season saw epic battles between the two teams
