Kawasaki 440 Engine info

Does anyone know where to find specifications on the Kawasaki 440
engine family? I am planning on using this engine in my project and
info on it is hard to find. I checked the Kawasaki corporate site and
of course google but no "real" information is forthcoming. I know there
has to be a spec sheet out there somewhere. There is plenty of info on
the 440 motorcycle engine
I need details to find out how I need to alter the engine mount on my
plane - the original plans are for a Rotax 447.
