After many interruptions, I've finally achieved an engine hanging on the
front of my Zenith 801. Many thanks to Paul and Jerry for the engine mount &
continuing advice.

I've attached photos showing key angles, including firewall clearance,
overhead clearance, and the center mount brackets / turnbuckle. The
clearances worked out great. The engine couldn't have gone back any further
w/o the oil pan hitting the nose gear strut. As you can see in the photo's,
it absolutely couldn't go any higher. I've also fitted the alternator, and
there's plenty of room for it in all directions.

Congratulations on your success. I'm curious about the lack of a direct
attachment of the motor mount to the upper firewall center point where the 2
braces from the forward spar intersect the firewall. Have you worked out the
load path from the firewall to the wings? In my conversations with zenith
personnel, this was a very important connection point in an engine mount in
the high wing series.
