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.]
The Pratt & Whitney R-1830 1,200 hp radial aircraft engine as on display at the National World War Two Museum in New Orleans, LA. Out the total 173,618 R-1830s that were built during the war, Buick made close to 74,198 of them in the government owned plant in Melrose Park, IL, west of Chicago. This was 43% of the total. The engines built by Buick were used exclusively on the 18,190 Consolidated B-24s until April 1944 when it was contracted to build R-1830s for the C-47. It should be noted that Chevrolet was built R-1830s for the B-24 and C-47 also. Author's [David D Jackson] photo.
