The block of the Ferrari 348 had a revised basic geometry and featured a five-main bearing crankshaft and nikasil-steel cylinder liners surmounted by heads with revised geometry and centrally mounted spark plugs for a high potency, high volume, high speed flow for spark and combustion potency. The valves were actuated through bucket tappets by twin overhead camshafts. A combine of side-mounted radiators cooled the engine. A dry sump lubrication system provided necessary lubrication underneath all conditions.
Fuel was delivered from the center mounted tank to the intake runners through fuel injectors by a high pressure pump. Air was delivered from the high aspect scoops through articulated rubber and steel tubes to a filtered sq. air-box more than the transmission and from there through twin throttle bodies to the intake manifolds situated more than the engine. an advanced Bosch Motronic M 2.5 fuel injection and ignition system controlled delivery and spark until 1993 when the M 2.7 replaced it. Exhaust gasses flowed through a steel manifold and a tuned exhaust system with catalytic converters.
F348′s power was transmitted from the fly wheel to the back wheels through gears, clutch, final drive and constant velocity joints. The new transmission was mounted across the rear of the engine at intervals the sort of pre-turbo Formula one racing Ferrari’s. The clutch sat at the rear of the drive train. The configuration sited the whole drive train four inches lower at intervals the chassis than had the previous model.
The Ferrari 348 was powered by 3405cc V8 engine, introduced with the automotive in 1989. The 90° lightweight alloy V8 had 10.4:1 compression, and 48 valves actuated by 4 overhead camshafts. It made 300bhp at 7200rpm and 237lbs-ft at 4200rpm. The V8 was put in longitudinally within the 348, bolted beside the transmission and rear suspension into the removable tube-steel rear sub-frame, a big innovation.
