The pre WW-2 engines were 2 cyl air cooled Waukesha, the mid years was as described here, the engine proved to be OK for those who serviced the coolant of the era religiously, but was not happy as a consumer engine. This from Crosley Service Motors. Crosley CoBra Engine 1945-1949 The post-war Crosley models were powered by an innovative four-cylinder, overhead-camshaft engine, originally designed by Lloyd M. Taylor during WW2 to run generators. Instead of being cast as most other engine blocks were, it was built up from an assembly of steel tubing and stampings. These parts were assembled in a jig, then copper brazed together at high temperatures. The copper brazing process gave the engine name, CoBra.
With a 2.5″ bore and 2.25″ stroke, engine displacement was 724cc, or 44 cubic inches. A vertical shaft with bevel gears was used to drive the overhead camshaft instead of a more conventional chain drive so that the lubricating oil could be fed up through it to pressure feed the cam bearings. The CoBra engine had a compression ratio of 7.5:1 making 26 horsepower at 5200 RPM. Even though Crosley cars had an all-new body and a new engine, most of the rest of the chassis and brakes were left over from prewar production.
The CoBra engine was prone to rust in the water jackets when used with regular water and antifreeze, and also prone to damage from overheating. This wasn’t a problem with military mechanics trained to prevent these issues, but became a problem once the engine made it into the general public. By 1949, these issues became large enough for Crosley to redesign the engine in cast iron, replacing the CoBra with a cast-iron block, which would power all Crosley cars through the end of production.
