Went to the Motorsports Hall of Fame at Daytona International Speedway Today

I think those Ardun overhead valve heads are on a flathead Ford block
I have never seen the overhead valve heads conversion .in person, very rare to include the intake, which had a 3 bolt Stromberg carb on it. Notice the magneto in the timing cover
Ardun, Arkus Duntov was the creator of the Corvette.
