Ford's foray into the Indy 500 in the 1960s is a motorsports story for the ages. In 1963 the company used a pushrod engine derived from their successful 260ci small block V8. After nearly winning the race with that effort, engineers were turned loose to build the ultimate version of the engine.

What they designed was dual overhead camshaft, 255ci V8 that made peak power at 8,000 RPM, was tested to within an inch of its life, and arrived at the Indianapolis Motor Speedway ready to win. While 1964 didn't go Ford's way, the engine would win 7 Indy 500 races, countless USAC events, and spur the development of a horsepower war that lasted into the 1970s with turbochargers and ever increasing speeds.

This is an in-depth exploration, starting in 1962 of the development of this awesome engine.
