Ferrari 330 P3/4
0846 the only P3/4 was originally built as a P3 by Ferrari. It was modified in December 1966 to accept a P4 engine and it's wheelbase was changed P3 2412mm to P4 2400mm. It retained its P3 nose and chassis becoming a P 3/4. This vehicle was damaged in an accident at Le Mans and was discarded by Ferrari. Recently, many components of the original P3/4 0846 have resurfaced in the possession of exotic car collector and enthusiast James Glickenhaus, a former movie director and stock exchange magnate. Although both he and David Piper (from whom he acquired the car) thought it one of four replica chassis constructed with the blessing of Enzo Ferrari in the late 1960s, it appears that nearly all of the tube frame chassis and other components from the wrecked P3/4 0846 are part this car. This discovery has stirred debate  Ferrari Market Letter recently reported: "While Ferrari insists that 0846 was scrapped and is no more, a car exists with strong claims to be the resurrection of that car." Its tube frame chassis appears to be a P3 modified to hold a P4 engine, as was the case with 0846 exclusively, and the damage from two contemporary racing accidents appears in the frame as well. The car's transmission, engine heads, and steering rack also include the correct Le Mans scrutineering marks, linking them to P3 0846 and P3/4 0846 of 1966 and 1967. P3/4 0846 was road tested by Car and Driver magazine.
Since 2000 Ferrari S.p.A has published the fact on their official web site Ferrari.com in the owners section that Ferrari P 3/4 Chassis 0846 is owned by James Glickenhaus.
