Wow - that looks like a very clean old 109. Great find...

Cool truck. Like the tailgate option. Those tires look big and beefy. Kind? Size?
We have that same engine in our Dormobile, known as the Euro 6. The other 6 used was the NADA 6 which has a different cylinder head and intake manifold.
I got fed up with the SU pump, new ones, rebuilt ones, solid state points ones. Finally replaced it with a Facet. I hope you have better luck as the Facet can be loud.
The six has a much flatter torque curve than the four, making it less slow on the road. I like the way it sounds, too.
If you don't have a spare water pump, start looking. Or a rebuild kit for one.
Keep the valve clearances in spec, especially the exhaust ones. I have found it is easiest to remove the exhaust manifold to adjust them.
It is an interesting engine, Inlet of Exhaust, or IOE, designed to have relatively large valves and be able to run a higher compression ratio than other post WW2 engine designs. That said, they only put 7.8:! pistons in these. I have wanted to try the 8.8:1 pistons from the NADA 6. Here is a cutaway drawing of the engine.
