Ernest,

It's a great question. However, make sure that you're comparing apples to 
apples. The computation is harder, unfortunately,  than just figuring out 
labor at shop rates.

Contary to rumor, there is some labor time involved in installing Lycomings. 
And some additional costs You've still got to buy a mount. Lycomings 
sometimes come with or without all the accessories, which then may be 
purchased separately. Fabricate some cowling baffles  for your updraft or 
downdraft cooling system. Put on an Ellison fuel injector system? Add that 
in. Emag or Pmag? Same thing. And add in the time to install and get them 
right.

I'm building a pusher and Cozy builders always have to buy a prop extension 
of 6" to 8," which costs about another $1000.

One day when I entertained unhappy thoughts about all the problems of rotary 
installations, I worked on the Lycoming side of the equation and was 
surprised to figure out all other other stuff I still had to do if I gave 
into the dark side like...you know who. (Hi, Rusty!)

Just do a good job of comparison if you get some numbers.
