Ardun, Almost

I was working this morning, when a friend of mine stops buy and says, "look what I bought at a swap meet".
The whole motor came apart. There are no internal pieces, I still think it's pretty neat.

Very cool Ken, super detail on that one. Barb, Ardun stands for Arkus Duntov, same guy who was so involved with the development of the sbc. These heads were a way for trucks that ran flatheads to produce more hp, and racers grabbed onto them for that same reason. They replace the flathead heads and turn it into an ohv V8. Very desirable.

The ARDUN overhead valve conversion for the Ford flathead was the brainchild of a Russian engineer, Zora Arkus-Duntov. He used the first two letters from Arkus and the first three letters from Duntov (Ar) and (Dun) to name the new creation.

I'm lead to believe he was living in England in the late 40's and that he created the OHV to provide more power for the Ford flathead motors that were used in garbage trucks. There are others who remember it differently.

Mr. Duntov moved to the United States, signed on with GM and became the "Father of the Corvette" as an engineer for General Motors. He further designed many, many performance parts that would allow Chevrolet to reign as the primo performance marque. People still talk about the "30-30 Duntov cam" that he designed for the little 265 Chevy small block of 1955/1956. I think NTFDAY has one in his garage.

Yuppers, if you had a sbc, it was either the 30-30 Duntov or the Dempsey Wilson-----hmmm.--memory is a strange thing... wasn't it called the Dempsey Wilson 7-11 or something similar????

Ken, one time I posted something I heard one time. It went "when you build a flathead you will never spend so much money to go so slow." :D

The flathead lovers were up in arms about that statement. :LOL::LOL:

That's a neat little trinket, there.
Arduns are the stuff of legends - maybe small legends, but------

25k for a flattie?? :eek::whacked: In 1959, it cost me $500 to rebuild an 8BA, complete with new pistons, cam ("3/4 race"), ground crank, Offy aluminum heads, and a three pot intake; that was a truly sizeable sum at that time, though, took me six months to save it up. Ran it against a guy with a 332 in his '51 Vic, and nosed him over a the lenght of a mile; the two cars were almost identical, other than the engines.

I can see why that didn't go over too good, truth hurts sometimes!! I like to use them for the theme of the build.

A friend of my dad had a '48 Cadillac with the last year flathead. I was in love with that motor through my childhood. I have no idea why I have never built one. I should put that on my project list.
