Obscure Engines: 1964 Ford DOHC Indy Racing Engine

<div>Ford has an amazingly rich road racing history, plenty of it in the years leading up to the introduction of the Mustang. In 1963, Ford (in collaboration with Lotus) embarked on an ambitious project to build a car with a lightweight, powerful, low-displacement V8 engine. Between 1963 and 1970, when Ford pulled out of all forms of auto racing to focus on safety improvements in passenger cars, this high-tech engine would take 73 wins - more wins than all other competitors combined.<br />

Custom car builders are dropping these motors into wild rides <a href="http://www.stangtv.com/forum/ebay-find-day-crazy-custom-ford-5995.html" target="_blank">like this 1962 Falcon</a>, so the legacy continues to live on. Make sure you check out the <a href="http://www.quadcamford.com/home.html" target="_blank">Quad Cam Ford</a> website for a wealth of information about this awesome motor. <br />

The engine started out as a 260 V8 and was given bumped up compression to 12.5:1, and a revised exhaust manifold and intake, with ports for four 46mm Weber downdraft carburetors. The engine was then moved into an aluminum block and lost five cubic inches, but shed many pounds as well. This engine weighed in at 344 pounds, and made 376 horsepower on 103 octane reliably for 500 miles. That was good enough for the racers Ford intended to enter. Jimmy Clark placed second in the ’63 Indy 500 driving a Lotus 38 racer, and Dan Gurney placed seventh. This strong showing encouraged Ford to invest today’s equivalent of $66 million into the development of fewer than twenty such engines. <br />

In order to win, Ford determined that they needed to add fifty horsepower without adding fifty pounds to the engine. The result is a dual overhead camshaft engine, with vertical valves and exhaust ports exiting on the inside of the cylinder heads (where the intake usually goes). Weighing in at under 400 pounds, this engine produced 425 horsepower on race gas. The revised exhaust system was even better than the short stacks that most racers used in those days, and would lead Ford to victory after victory in the coming years.<br />

Just twenty of these rare engines were produced in 1966, and they were never offered to the public, though they powered some of the most famous racing cars in history. Among those cars was the infamous GT40, which scooped up victories at the 24 Hours of LeMans four years in a row. Ford won five or six Indy 500 races between 1965 and 1970 using this engine, and they dominated every other race they entered. These engines were $23,000 back in the 1960's - the equivalent today would be approximately $153,000. But Ford didn’t stop there.<br />

<br />
There was even a turbocharged version of this engine, reduced down to 159 cubic inches. Because Ford cylinder heads were not part of the block, however, their engine suffered noticeable boost leak (unlike the Offy engines of the time). Running 80 inches of manifold pressure, the engines made about 825 horsepower, an astounding tally considering this was over forty years ago. <br />
<br />
Unfortunately, development of these engines came to a dramatic halt when Henry Ford was forced to admit his company spent far more money on racing than safety. But the legacy that these engines left us can be felt in today’s 4.6 and 5.4 liter modular motors, as well as the new line of EcoBoost engines.<br />
