I can think of two inverted "V" air cooled aero engines that were
produced in quantity.
One is the German Argus As 10C 240HP used in the Me 108 and the Storch
and the other is the American Ranger V-770 inverted V12.
See: http://www.oldengine.org/members/die...ord/Ranger.htm
and http://en.wikipedia.org/wiki/Argus_As_10

LOM's are still in production: http://www.moraviation.com

I thought the original question was about inverted "V" engines. While the
LOM and Mikron engines are excellent products, they are inverted I-6 and I-4
engines, not a "V".

BTW, neither the LOM or the Ranger engines suffer from 'hydraulic lock'
which seems to be mostly related to P&W radials. I owned a Ranger inverted
in-line 6 which powered a PT - 19 and it never even smoked on start. I also
flew a Zlin with a LOM I-6 and it didn't give problems.

I think the inverted engines allow a nicer looking cowl and they do improve
the pilots visibility forward and down.
