Here's some info on the Lincoln flathead V8; http://www.vanpeltsales.com/FH_web/f...s-337bigV8.htm

There's not much evidence to support the Ardun = Chrysler story, nor is there any to challenge it either. There are some strong similarities in design, so the assumption is a natural. Duntov lost control of the company in the late '40's, but it's unclear who took over the tooling, perhaps a company by the name of Stevens. What is known is that, before going to work for GM, Duntov went to work for Sydney Allard in England, and that shortly thereafter the Ardun tooling came into Allards possession and they resumed production. Tags were added to the valve covers that said "Made in England". This was after 1950, so it's unlikely that Chrysler ever "owned" the tooling, and given that the Ardun was a near copy of the French built Talbot in configuration, it's also unlikely that they had patents on anything other than possibly as application specific to the Ford integration. But that's what adds to the lore................all the possible permutations, real or imagined.

BTW, that one on ebay is at $25k and hasn't hit reserve, but must be getting close as the seller has lowered the reserve.
