The little Crosley engines are an important piece of American automotive history.
Originally designed with money supplied by Henry Kaiser (Kaiser Aluminum), they were an amazing little automobile. The engine itself was a rompin', stompin 44 cubic inches, and a single OHC design that used shims above the vaves to set valve clearance, a design that Kawasaki later used in their 4 cylinder motorcycle engines first introduced in 1973.
The Crosley block had the reputation for being nearly 'bullet proof', and they were routinely turned at over 8,000 rpm in inboard racing hydroplanes, and in Class "H" modified racing sportscars. An Italian designer by the name of Lorentzo Bandini even designed a twin cam head for the little engine, and the little Bandini racer was a force to be recconed with for several years in early sportscar racing in this Country. The little car weighed in the vicinity of 850 lbs., and could break 120 mph. All of this in the 50's, and with 44 cubic inches.
