Mazda engines are not designed to be cantilevered off
the front cover!

I would agree with the above statement.  The front cover is thin, and
non-structural quality.  However, it sounded like the plan written included
attaching to the end housing through oil pan bolts and something at the
top.  This *may* be doable.  I chose to build a proper subframe for mine
although I would have liked to cantilever.

I will take this opportunity to say one other thing about plugs up.
The hottest part of the engine is at the plug side and as such this is
where you are most likely to get steam pockets. You cannot vent 
every nook and cranny. It is better to have the cool part of the
engine at the top as it was designed to be so the steam pockets will
go there and be vented as Mazda designed it.

Continentle is fighting this battle as we speak with their line of
water cooled piston aircraft engines.

Given what we have learned in the past year about this configuration
I am going to take all reference to the plugs up configuration off 
the ACRE NL web site.
