OK...
For the sake of discussion, consider the amateurs eliminated.

Who is left with a reputation of converting and selling hundreds
of VW engines that yield PROVEN equal reliability, performance
at a significantly lower overall LONG TERM cost than suitably
rebuilt aircraft engines... like the 65 hp Continental, for example?

Great Plains maybe?
or Revmaster ?
Aero Vee comes to mind...

have a look here for German requirements to automotive engine conversions
