The Maserati Tipo 107 engine, commonly known as "Maserati four cam V8", is a family of DOHC 90° V8 petrol engine developed by Maserati, first introduced on the 1963 Quattroporte and used until 1990. These engines displace between 4.1 L and 4.9 L, and produced between 260 and 330 PS (191 and 243 kW; 256 and 325 hp). F

Description

These V8 engines have a 90° angle between the cylinder banks, an aluminium block with cast iron sleeves, aluminium cylinder heads with reinforced valve seats and hemispherical combustion chambers. The crankshaft has a crossplane configuration and rotates on five main bearings. Engine timing is by two overhead camshafts per each cylinder bank, directly acting on sixteen poppet valves, and driven by two timing chains. All variants were naturally aspirated, and fed by quadruple Weber DCNF twin-choke downdraft carburettors.

Tipo 107

The Tipo 107 variant took its denomination from the chassis code of the first generation Quattroporte, that brought it to début in 1963 in 4.1-litre form. It used wet sump lubrication.
