1989: 348
The 348 was powered by Ferrari’s 3405cc V8, introduced
with the car in 1989. The 90° light alloy V8 had 10.4:1 compression and
48 valves actuated by four overhead camshafts. It produced 300bhp at
7200rpm and 237lbs-ft at 4200rpm. The V8 was installed longitudinally in
the 348, bolted along with the transmission and rear suspension into
the removable tube-steel rear sub-frame, a significant innovation. The new block had a revised basic geometry. It 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 efficiency, high volume, high speed flow for spark and
combustion efficiency. The valves were actuated through bucket tappets
by dual overhead camshafts. A dry sump lubrication system provided
necessary lubrication under all conditions. A pair of side-mounted
radiators cooled the engine.
