Does anybody know what the price is for just a
4130 Lycoming mount that fits a Vans RV6?

Don't know for a vans but Teamtango was asking $1000 for theirs, which is still
  cheap, considering,

Maybe it is time to re think the traditional steel tube mount for
composite airplanes. Perhaps the cowling can be used like the
Questair Venture.

Paul, My fuselage has wide stringers down both sides from the canard to the
rear of the lower fixed cowling.  There will be embedded hardwood blocks as
hard points for canard,engine mounting and landing gear.  I never compared
the weight to a tubular truss but went with the stringers so as to not have
a bunch of truss tubing running through the engine compartment making it
hard to fit radiators, cooling duct work and the exhaust system.  This method
is fairly simple with a composite pusher configuration.  Doing it in an RV
might be hard to get the load paths to reinforced areas and still have
maintenance access to the engine with only the top cowl removable.

George, how strong do you suppose your stringers are to handle the loads,
are you calculating for about 6G ultimate loads?
