It was a shot in the dark. I know they are probably pretty rare. The old early modifiieds with inlines are often shown with SU’s if they don’t use Strombergs. I was just looking for something different. I did see a Buick I8 with a homegrown manifold with an old AFB 4 barrel on it. But like the Strombergs, they are directly in the drivers field of view. That probably why the sidedrafts were popular.
