SPANISH V8 ENGINES

Spanish V8 engines

Spanish truck and sportscar company Pegaso made around 100 cars in the 1950s and 1960s. There were two types of engines; the Z-102 and the Z-103/4 engines.
The Z-102 first introduced in 1951 engine was an advanced design sporting quadruple camshafts (two per bank) and had 2 valves per cylinder. It was available with 1, 2 or 4 twin Weber carburettors and either normally aspirated or with one or two superchargers. It had three different capacities, 2472 cc (151 CID), 2816 cc (172 CID) and 3178 cc (194 CID) and made between 165 bhp (123 kW) and 360 bhp (270 kW).
The Z-103/4 developed in the mid/late 1950s (the first prototype was made in 1954) was a much simpler design destined to power a new series of luxury and sportscars. It had a single central camshaft and 2 valves per cylinder actuated by pushrods. It had hemispherical combustion chambers (like the Z-102 engine) and twin spark plugs. It was available with three different cubic capacities as well, 3900 cc (238 CID), 4500 cc (275 CID) and 4700 cc (287 CID). The 3.9 L engine had a twin Weber carburettor and the 4.5 and 4.7 L engines 2 quadruple Weber carbs, which gave the later a power output in excess of 300 bhp (220 kW). The very few engines of this type produced were installed in Z-102 cars.
