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.
