Deutz builds some fairly large air cooled engines for stationary
use. The largest one on their site is just over 170 HP.
One for mobile machinery use is rated at 322 HP. I didn't check to see
if that's maximum or continuous.
They used to sell Deutz engines for irrigation use at my workplace
years ago. One of the advantages is the engines could run hotter and be
more fuel efficient.
Wisconsin used to build air cooled gasoline engines.
Minneapolis-Moline used them on their combines. Also long ago.

I had an old Bobcat skid steer with an air cooled Wisconsin engine.
Lasted a long time, but I sold it because it other stuff was always
breaking down. Engine still run well. Biggest problem with engine was
the carb likes to stick and needed to be rebuilt fairly often.

It got lots of hard use.
