Motor Block and Cylinder Exchange Service for Ford 4-Cylinder and V-8 Automobiles, 1933

In the 1930s, Ford operated an engine exchange program through its dealer network. It kept Ford workers employed during the Depression, and it furthered Henry Ford's personal commitment to reducing waste. Worn engines were sent to the Rouge where parts were repaired or replaced as needed. Ford dealers sold reconditioned four-cylinder and V-8 engines to the public for about $40.
