The Cost for the ZDZ was more than the OS 1.60 by more then twice as much.  
Right?

It will  be very interesting to see your results.  I had the chance to 
build and  fly the Abbra with ZDZ 40.  I was able to comparare the same plane 
with  OS160 back-to-back.  Clearly the ZDZ 40 was behind in power (or  
power-to-weight ratio) when compared with the OS 160 when doing the  Master 
schedule of that time.  I am sure that less fuel consumption  with less BTU content 
means less power.  The Abbra with the ZDZ 40  was ~3-4 oz over 11 lbs.  The 
OS 160 Abbra was 9.8 lbs.  I am  not sure now what the new gasoline engines 
manufactures are doing to increase  the power.  I believe that an 
improvement in the design of gas engines is  required to make it usable for  pattern.
