as well. In a departure from previous Ferrari designs, the valve angle was reduced three degrees to 54° for a more-compact head. The dual camshafts also allowed the valves to be aligned "correctly" (perpendicular to the camshaft) instead of offset as in SOHC Ferraris. It was a dry-sump design with a huge capacity. The engine retained the bore and stroke dimensions of the 275 model for of displacement. Output was at 8000 rpm and of torque at 6000 rpm with six 40 DCN 9 Weber carburetors. 365 The 330 Colombo engine was enlarged with an bore to for 1966's 365 California, retaining single overhead cams and wet sump lubrication. A reworked engine with four camshafts was used in the GT/4 models. The 365 GTB/4 Daytona was the only 365 engined car featuring dry sump lubrication.

The carburetors were replaced with Bosch K-Jetronic fuel injection in 1979. In 1986 the engine was bored to giving a displacement of .
