- Ford "Calliope" V-8 Automobile Engine, 1968 - Ford engineers developed the aluminum-block 427-cubic-inch "calliope" engine for the 1968 Le Mans 24-hour race.

- Drawing of the 1893 Kitchen Sink Engine, "Diagram of 4 Cycle Internal Combustion Engine" - This 1934 diagram uses Henry Ford's experimental 1893 Kitchen Sink Engine to illustrate the operation of a four-stroke internal combustion engine. Stroke one draws air and fuel into the cylinder. Stroke two compresses the air-fuel mixture. In the power stroke, a spark ignites the mixture which forces the piston down, turning the crankshaft. Stroke four pushes exhaust from the cylinder.
