According to Dave Williams engine weight chart (fixrambler.com/art62.html)
the model A engine was 475#. You likely need to add the radiator, fan and
possibly the intake and exhaust to that. They were stink heavy due to thick
wall casting and the poor iron available at the time. Found they got 25 to 30
US MPG back then. Where is the progress? '65 Mustang I6 rated at 30MPG also. I
think we took a step backward like drunks somewhere along the way!

Yeah, but the gasoline was pure, not diluted with crapenol like
today.  Also the top speed of a model A was not high enough for aero
drag to be a factor! ... and they ran on skinny, high pressure tires.
