Every major automobile manufacturer offers a line of industrial
engines. There is also an extensive network of professional over-haul
shops that specialize in industrial engines.

For 2008 GM is introducing lighter weight Brazilian built utility
engines to replace the all-cast-iron models that have been standard
since the late 1940's.

The world can't run without utility engines for deep-well pumps, air
compressors, portable arc welders, orchard sprayers, fork lifts, all
manner of farm equipment... Many of these engines are an EXACT match
for the Model A but being of modern design, they offer better
durability and reduced fuel consumption, typically at less weight.


INteresting. The only one I know of commonly used for aviation is that
little 2 cyl Onan they put on Quickies. I know some ultralight guys use
the
little Continental 084s as well.

Not sure whether the little Onan boxer is still in production. Most of the
little opposed cylinder flat heads have been replaced with overhead valve
Vee-twins. I strongly suspect that the switch to Vee configuration was to
fit the new engines within the width of the equipment that the older flat
head engines typically powered--but I really don't know with any certainty.

I looked for a little info on the Continental O-84 and could only find that
it is a 4 cylinder of 21 cubic inches per cylinder. From that, I would
expect a power rating of 40 to 50 HP and a weight of 90 to 105 pounds, which
would be appropriate for a single seat LSA with a gross weight of 600 to 650
pounds. But, I don't know the actual specs and am curious to learn more.
