Unfortunately I have not received any replies yet. 
I may have been
too long in expressing my perspective, so people dont want to read it.


I feel ECi is the way to go. 
Best prop that I have found for this
bird would be MTV-12-B/175-59b 

I have checked with MT, it should fit
this engine. 

Miro - Have you received any responses on your engine
prop question? I am also building a LNC2 MK2 and I'm at the point where
I need to consider engine/prop combinations. I also like the ECi
engines.

 Thanks

Ladies and gentleman,

If you can help me out with this
discussion.
I am getting into process of building 360 MKII with long
cowl and long
engine mount.

I have been doing a lot of brain storming
about which engine to put in,
and here are some of the conclusions, feel
free to comment

----
I have been looking at IO-360 with stock 200HP+
engine.
It is typically angled valve engine
I find it to be too
expensive for what you get.
It is a smoother ride by heavier cause of
the counter weights it has for
torsional harmonic suppression on
crankshaft.
It is a lot of money and weight penalty for a slight
increase of performance.
I see guys actually using short mount with this
engine if you go for three
blade MT prop
----

Regarding prop, if you
want three blade, the best solution on the market I
found would be
MTV-12-B/175-59b

----

For Lancair 360 MKII airframe

I find it optimal
to go with ECi IOX-360.
With 8.5:1 pistons, ECi is claiming to have
188HP.
ECi cylinder seem to be very advanced on design.
I feel that I
would benefit with going additionally with front-horizontal
cold air
induction and 7deg angled intake. I feel that angled intake is
actually
a way for you to line-up with cowl front air-intake

I am not sure, if
this engine with cold air would fit standard 360 long
cowl, or I would
need to perform some modifications (with cold air, engine
is higher)?!..
let me know if you know more

If used with three blade MT prop, you do
not need counter weight on crank.
That prop can take more
abuse

Superior has a similar product, XP-360
Similar configuration to
ECi, cold air and everything... But they do not
have advance cylinder
design as ECi does.
But they do have revolutionary new camshaft and
roller lifter design,
which is not available with ECi engine.
I feel
that roller lifter design is not significant performance gain.
As far as
I am aware XP-360 is rated to 180 HP

I do not want to offend anybody
here, I am just openly expressing my
amateur overview on possibilities I
had a chance to investigate, I am open
to all comments and suggestions
on this subject

Thanks All!!
