Fiat 1500 OSCA Coupe
Instead of the pushrod style engine fitted to regular Fiat 1200 sports cars of the late 1950s/early 1960s, the OSCA version is fitted with the 1491cc (1.5L) twin-cam (DOHC) inline 4-cylinder motor designed by the OSCA company owned by the Maserati Brothers. Though OSCA designed the motor, they licensed the design to Fiat to bench-assemble and hand fit the engines themselves into those cars.
The OSCA engines had specific cast iron blocks, forged pistons, con rods and crankshaft. The DOHC head was cast alloy with chain drive for the two camshafts and a Weber carburetor.
This one is a coupe version which the owner tells me is rather rare.
In this photo we can see the rather novel steering arrangement just aft of the engine. Close to the viewer is the steering box. The steering column shaft comes through the firewall. On top of the box is the Pitman arm that turns within an arc conveying motion to a 180 degree bellcrank mounted near the center of the car. The lower part of the bellcrank imparts a side-to-side motion to the steering links attached to both wheel carrier uprights in order to steer the wheels.
