The Iron Duke popped up in the late 70s and lasted through the 80s. They had some similarities to the Chevy II engine but I don't think there was much in the way of parts interchange.
The Chevy II 4s were used by Mercury Marine for a very long time. I know they survived into the 1990s and maybe later.

How about a 1982 Camaro with a 151ci Iron Duke 90HP / 120 NHRA HP

U/S or U/SA at 2570#

OR

SS/PA or SS/P at 120 NHRA HP and 2210# min weight...

Too bad that the Quad-4 never came in a rear wheel application, I think?????

That was a very trick engine…..

Also in Mail Jeeps. That's the source of the Chevy pattern 904's ,later used in Comp.

The story is they would have been real dogs, fully loaded, with a PG.

Friend of mine's father bought three old mail jeeps for his pest control business. I drove one at Southland Dragway in Houma around 1974. If I remember it ran 24 seconds with the sliding door opening on the leave.

The Iron duke was used in various cars when I worked as a line mechanic in the mid to late 70’s. It had both intake and exhaust ports on one side of the head around 1976 and was changed the following year to intake on one side and exhaust on the other side. Many engines from all manufacturers were used in industrial applications long after they were discontinued in vehicles. The iron duke was one used a lot to power generators as well as marine engines. It had a very long life in various configurations!

Ah ! Billy and I have talked about that one.
Nobody has had to use one with a 302 yet.. It might come to that, eventually.
Take a look down through one, with the throttle plates and the top flapper open, and let us know what you see ;-)

How about one of the 68-74 Opels in the Guide? A 1971 Opel 2-dr sedan or wagon with the 115/75 2bbl L-4 has a minimum weight with driver in T of 1880lbs. It can go as low as 1790lbs in R.
