20's Dodge video
Hawklover's Ford post reminded me of this Dodge promotional video. Searched, couldn't find it posted earlier but if so, my apologies.

Wow! That would loosen the joints in a wood-framed body!
I found some .030, 4-13/16" pistons for an early 20's Dodge at Naugle's recently. They are "Permite 20" aluminum, which was quite an innovation back then, and have 4 rings. Flanged 1-5/8 rod bearings appear to be removable insert type, rather than babbited.
