"H" has been used over the years, here and there, like 'V' in V-8 to
designate horizonally oppsed engine.
the first time I ever saw it used was a BRM Formula One racing engine , in
the UK, .........it was two horrizonatally oppossed flat 8's with the two
cranks joined by gears - they called it an H-16.
( there thinking was that piston surface area was the key to high power
output, and to keep bore/stroke ratio rasonable ........that meant lots of
cylinders.
They went overboard though- complexity, friction, and weight doomed the
engine from the start ).

The SVX subaru engine - opposed 6 ......right on the plastic engine cover it
says "H6 24 valve" .
Personally, I like 'horizontally oppossed' over "H" or 'boxer.'

how's your H-6 air cooled engine and vanagon doing Vern !?
I sure would love to retrofit subaru fuel injection to it !
how about this ..........we'll use 4 cylinder subaru injection, we'll weld
up an intake manifold, and we'll put 4 injectors in a central location
.......
a lot like Throttle Body Injection systems are , but we'll have 4 centrally
loacted injectors .......feeding the six cyclinders.
Just a thought.
I saw an 88 Volvo 740 turbo with water cooled bearings in a junk yard
today - perhaps your engine would like a mild boost too .
