Marc,
Thanks for the very informative website. I admit that the number of things the builder is left to "make work somehow" with the 390 gives me pause. Or maybe it's that way even with the IO-360 package?
Now the big question: Was it worth it, and would you do it again?
I've been thinking about the 390 because the price is attractive - it's a lot lower than the 200HP IO-360, which seems backwards. Hmm.
