I finally got the '74 2.0L running well and went for a 20-to-30-minute drive. Temps were in the upper 80s and I'm not sure if the car was getting to hot.
Since there are no digits on the gage, I need to ask. I found a drawing of gages, so I think I'm in the 240 area. Not sure if the temp was still going to rise since I was back at home. The photo is from the passenger seat but from driver side, the "P" was mostly covered by the needle.
Am I still in the safe area? Thanks for any knowledge on this.

Lest anyone accuse me of just propagating my own mythology here is an excerpt from an engineering text on air cooled engine. Note: this book was first published in 1961 and second edition in 1972 . . . So again Dino oil era.

120C =248F
80C = 176F

If anyone is interested in this book here is a link to 1st edition of an otherwise expensive book.

Correction to my previous post
The Bruce Anderson book doesn’t reference 180F as max temp - my mistake

It is confusing and contradictory though. At best he’s saying 200F oil but then goes on to say 220 is high end of proper operating temp. I think people latched on to the lower number thing less is better (not true). I clearly latched onto that same lower number in my memory. (IMG:style_emoticons/default/headbang.gif)
