Leif:
The motor I refer to is the Willys F-head. They started making F-heads around 1950 or so, and continued to make them until the 1970's or there abouts. Mine is a six cylinder 161 cu in. Willys used it in station wagons (2 wd) and the Willys Aero cars. Kaiser also used it in some of their cars. And they (6cylinder) were used in Brazil for a number of years in cars and Jeeps. The more common F-head was the 134 cu in four cylinder used in Jeeps.
Sincerely:
Paul...aka xerxes
