That first engine photo powers a German import. The model sold reasonably well in the US in the second half of the '60's and into the first half of the '70's. With the twin carbs, it was the optional power plant. Although it was not a sporting vehicle, "sporty" models were made. This engine bay is actually connected to a stationwagon - which I would love to own, it was beautiful.
Just ask if more clues are wanted.
