I don't know the difference = between all the variants of the IO-360, parallel valve.  But, you = can read about it here if you haven't = already.

 

For starters I do know a few = things.

 

Get a forward facing sump for = sure.  You can bolt on a Superior or other brand cold air sump = on just about any of the 360's.  This will allow you to make a much = tighter cowling.  A rear facing sump is out of the question as = your nose gear is directly behind the sump. (might fit with the = long engine mount?  I doubt it) But, I wouldn't let the = "stock" configuration make me pass up a good deal on an = engine.

 

In my opinion, I would get a = forward mounted prop governor.  The back of the engine is busy = enough I think, but I have the short engine = mount..

 

Compression ratio will depend = on what you want to accomplish.  If you want to run MoGas for example, need to keep it rather low.  = 8.7:1 and lower I think?

 

It seems many of the other = variants relate to what type of mag setup.  I have dual impulse = coupled Slick mags.  But, this is 2013 now, and if I was starting = over I would have some sort of electronic ignition on one or both = sides.  So again, the variant doesn't really matter as you would = probably not use mags anyway.

 

So in summary, I would buy = whatever is less expensive to get you the compression ratio you want, = and the forward prop governor.
