Larry, thanks for the reply.  I was looking for something a little
more elegant than the RV-4 mount that I had built previously (please
see the attached picture).  BTW, Paul has designed a RV-4 mount that
I like alot better than mine but mine is DONE and I'm not too keen
about building another mount unless I could just bolt the engine to
a conical type mount.

Ken,

That mount is interesting and the one that peaked my interest the most I
must say. The frame behind the mounts appears super strong. I especially
like that you brought a pipe in tension to the Bell housing end of the
engine. This is good for a static down force obviously but I'm trying to
figure out the load paths with a side to side movement or negative force
stall.  Correct me if I am wrong please but wouldn't the approx. 35 " moment
still fulcrum directly at the rear rubber mounts?

Doug,
Ken's mount interests me as well.  Do you think the "pipes in tension to the
bell housing" you mentioned would obviate some of the concerns about
streched engine bolts and unatural load transmissions through the engine
casing from end mounting?  I wonder if these could be easily retrofitted to
standard dynafocals without getting in the way of exhaust & intake
apparatuses (or is that apparati?).  I'm assuming you are the same Doug Fir
that posted earlier on this thread.
