The earliest flatheads sported 21 head studs, 221 cubic inches of displacement and Babbitt bearings. As the engine grew, Ford added three more head studs (bringing the total to 24) and incorporated modern insert bearings -- a variety of other changes were rolled out over 20 years of development.
The 8BA casting on this engine's cylinder head means this engine is from Ford's final run of flatheads from 1949 to 1953.
Through the time-lapse video, you can see the intricate, and often unseen, design of the Ford flathead. Unlike the Chevrolet small block that Hagerty rebuilt last year, this Ford mill got dolled up with all the period goodies you’d hope to see: a reproduction Edelbrock Slingshot intake topped with a pair of Holley 94 carburetors and Edelbrock aluminum heads.
The video shows the engine being slid back into the 1946 Ford pickup from which it was removed at the start of the video -- then it is driven away. Despite the short six-minute run time, the video manages to show every aspect of the build through the string of 40,000 photographs.
