context_page_description: Crosley was a small, independent American manufacturer of subcompact cars, bordering on microcars. At first called the Crosley Corporation and later Crosley Motors Incorporated, the Cincinnati, Ohio, firm was active from 1939 to 1952, interrupted by World War II production. Their station wagons were the most popular model, but also offered were sedans, pickups, convertibles, a sports car, and even a tiny jeep-like vehicle. For export, the cars were badged Crosmobile.
  Crosley introduced several "firsts" in American automotive history, including the first affordable, mass-market car with an overhead camshaft engine in 1946; the first use of the term 'Sport Utility' in 1947, for a 1948 model year convertible wagon; and the first American cars to be fitted with 4-wheel caliper type disc brakes, as well as America's first post-war sports car, the Hotshot, in the 1949 model year.
  All of Crosley's models were lightweight body-on-frame cars with rigid axles front and rear, and engines with less than 1 litre displacement. With exception of the late introduced Hotshot and Farm-O-Road models, the vast majority of all Crosleys were built on an 80 inches wheelbase, and with leaf-springs.
context_section_description: The Crosley CIBA (Cast Iron Block Assembly) was a more traditional and more reliable engine utilizing a cast-iron block. Nevertheless it had a unique design. Instead of a removable cylinder head —  the combustion chambers, valve seats, cam supports, ports and cylinders are one casting, and the crankcase is another. In both the early and later cast-iron engines, the crankcase is aluminum. The 44.2 cu in (724 cc) engine produced 26.5 HP @ 5,400 rpm and 32.5 lb⋅ft (44 N⋅m) @ 3,000 rpm. 
  When Crosley Motors, Inc. was sold, the engine was renamed "AeroJet" and production continued. Production of the AeroJet ended in 1955 and the engine rights were sold to Fageol and later to a series of different companies ending in 1972 with the Fisher-Pierce Bearcat 55. Maritime modifications mostly included increasing displacement and converting the engine to operate with a vertical axis.
  In Europe the Crosley CIBA would be used to great advantage in 750cc sports car class, eventually maturing to a double overhead camshaft (DOHC) design used in the Bandini 750 sport internazionale as well as Nardi 750LM and Siata Amica.
