There are probably several other hemi V8 engines out in the world that are physically smaller than the Red Ram Dodge of 241 cubes. They would all be foreign. Here are some examples;

Daimler SP 250 roadster had a 2.5L (153 ci to us yanks) hemi, pretty compact. See a picture at the below link.

A Simca Vedette hemi, about the same displacement and hp as the Daimler, see it's relative size in the wav video.

Toyota makes a similar sized hemi V8 for the Japanese market, powers limousines if I recall correctly. Couldn't find an internet link with a quick search, maybe someone with more time could feret one out. There have been two street rods, both T buckets, that I've seen pictures of that used this engine. One was out of Texas, the other I think was Arizona.
