Aren't almost all engines technically "hemi's"? Or are there a lot of engines out there with really odd shaped combustion chambers?
According to Ford fanatic I once worked with, technically his Escort was a Hemi. He said Dodge had a great marketing thing going, though.
Most cars prior to the 1950s used what was known as a flat head, and many lawn mower engines still use the flathead design today because it is less expensive to manufacture.
I believe, thanks to CARB, that pretty much all lawnmowers and such now use OHV configurations. I know my relatively-new tiller does. For emissions reasons only. -- Jim
