Saab Superbird (aka the plywood Saab)

That is awesome! Do you know it it's the German Ford V4 or the Saab 3 cylinder 2 cycle engine powering this incredible machine?

I did publish this picture over at Facebook in the forum "Gamla custom bilar i sverige" which means Old Customcars in Sweden. One person stated that the form of the windshield made this "Superbird" a '67 or later Saab. Therefore and most likely the engine is a V4.
