1967 Ferrari Motor 365 GTB 4
4390 cm³ divided by 12 is the single displacement and thus (rounded down) the type designation for this engine or the Ferrari, in which it was installed. The received the nickname 'Daytona', the name of the racetrack in the
U.S. with the greatest sporting success.
The partially disassembled engine (see picture) had next the cylinder head also the block of aluminum and in it wet, cast-iron liners. The for twelve-cylinder standard cylinder angle of 60° results in a crankshaft with room
for two conrods on each by 120° moved crank pins. The then not yet completely normal, double DOHC design results in one for a regular series engine already a proper rated speed and 259 kW. It may not be unmentioned
the enormous amount of 6 double carburetors. But the engine not only fulfills sporting demands, it has a high torque, albeit at a speed that results in normal engines for maximum performance.
Further details are worth mentioning. First there is the dry sump lubrication, making possible an oil circulation of 16 liters. And the hemispherical-shaped combustion chambers that allow a reasonable compression. The
engine builds, despite the short-stroke construction relatively short, which points to a low centre distance. The carburetor system is supplied by two electric fuel pumps. The performance offered was good for about 275
km/h.
