Hi all...
I am keen to try and find out a bit of detail on these engines. I've picked up that they were made from 1941 to about 1952 when they were replaced by the pushrod OHV engine.
First, was any of the architecture of the earlier engines used in the later ohv models?
Next, does anyone know what the firing order was in the flathead inline sixes?
I have only ever seen one of these engines in Australia, installed in an army truck. In the main, for the duration of their manufacture we only saw the V8 flatheads here. Later we did get the ohv sixes in pickups and trucks, with the 1957-60 sedans marketed here as the 'Custom 300' having the ohv six fitted.
