I'm still trying to figure out the details of how the connecting rods were offset so that they could all share the same crank. I was expecting to see fins on the cylinders because they leave the front of the plane open so that there is plenty of airflow over the cylinders so I assume they were air cooled. Maybe that is just a detail that isn't worth the effort to draw.
The article that has the video for the following screenshots says the 1941 P-47 Thunderbolt is "considered as the most powerful single pistol engine aircraft during the time." Not only is "single pistol" a spelling error, I'm sure it had several pistons. In fact, the title of the article, "This P-47 Has the Roughest Sounding Radial Ever" confirms the engine is a radial.

Eddie Martinez I am surprised that they would let the lady on the right wear open shoes like that. I realize that safety issues weren't big back in those days. But, she could easily get her feet cut up.
Don Allen good tractor pulling and old school hydroplane boat motors.
[This is a Merlin V-12 instead of a radial engine, so I'm generalizing this posting to airplane engines. They are adding the shrouding to a P 40 Warhawk.]
