I am no engine maven, but all the diesels I am aware of have fairly high
weight to horsepower ratios.  The exception being the Zoche and I agree with
Brent, "it's the engine of the future and always will be."  There have been
so many engines that failed to be viable the odds are huge that Continental
or Lycoming will remain only practical choice--------------- ahh, if it said
Honda Aviation on it???
