I can answer for him on that one it is a certified engine used in a aero
commander I think. It is not certified now because of the oil pan made for
the
Lancair. I did the test flights on this plane in Ca and it is now in Fl.
Strong engine just needs a diffferent cowling for cooling on the lancair, it
has
the exhaust coming out the tope of the cylinders instead of the bottom. Ron

I’m not following you here. Updraft cooling? Why so? Is this an engine
specific specification?
