On second look though, a 1600cc engine was probably the upright.  Not sure if there was a difference in cc's in the later engine. Maybe it was the 1800?  I can't remember the minutia.  That later engine used in the last few years of the Bay's was a hot little engine that didn't seem to mind upgrades.  I believe that is where the old story that it was a "de-tuned" Porsche engine came from.
