The Ardun OHV heads formulated a famous standing in the scorching rod planet, they permitted people to modify their Ford Flathead V8 somewhat speedily into an motor generating 200 bhp or more, up from 65 bhp in stock trim.
The identify Ardun is a portmanteau of Arkus and Duntov, the hyphenated surname of Zora Arkus-Duntov and his brother Yuri, immigrants from Belgium by way of Russia who would go on to have an oversized impression on both the warm rod and sports car worlds in the United States all around the mid-20th century.
Over Video: This 15 minute very long online video gives an excellent glimpse deep within a Ford Flathead V8 that is been equipped with Ardun OHV heads.
The two gentlemen experienced arrived in the United States as refugees after the outbreak of WWII in Europe, they quickly turned their awareness and engineering acumen to helping the war exertion. They started the Ardun Mechanical Company in 1942, initially making dies and punches for ammunition and later on made parts for aircraft.
Right after the war they retooled, Zora and George Kudasch made a set of substantial-effectiveness overhead valve heads for the flathead Ford V8. The Ford Flathead V8 had turn into an virtually ubiquitous general performance engine in the United States because its introduction in 1932, as it was low cost to invest in and easy to repair.
Most likely the major issue with the engine was its propensity for overheating, largely due to an inefficient exhaust port structure that siamesed the two inner ports on every single side. This primarily impacted trucks, but it lowered overall performance in automobiles much too, and Zora knew that a superior overhead valve head would address the problem the moment and for all.
He took his style concepts to Ford who confirmed no curiosity in any way, a considerable miscalculation from the company as just a few small many years afterwards they would witness the introduction of the Chevy compact block V8 – an engine that blew them out of the water.
Zora and Yuri put the heads into output on their own, many flaws in the primary design arrived to light, and significant time was used ironing them out and turning them into a responsible, pair of large-effectiveness heads.
Incredibly hot rods and land velocity racers fitted with Ardun heads established a slew of world data out on the Bonneville Salt Flats, one instance set a C/Road Roadster record of 162.61 mph in 1951, generating over 303 bhp at 5,250 rpm.
To this day the name Ardun is lauded in scorching rod circles, and the enterprise was reformed to produce fashionable variations of the Ardun OHV kits for a new technology of racers. The only caveat being the entire package fees $15,950 USD.
