here are some photos of the Long-EZ motor mount mockup
with wood dowels and cardboard tubes. Even drawing this
stuff in 2-D it's difficult to know if it's really going
to work until you do something like this. Shown here is
the 13B front cover, but if it will work I still want to
use the 12A front cover.

Looks real good.
I think you need to go down on the wall thickness of that big tubing.
1/8 inch thick is going to be too heavy. 0.065 will be plenty strong.
Also the four tubes holding the mounts in position could probably be
1/2 inch OD .049 wall. So too could be the diagonals to the front of
the engine. Just a small 3/16 bracket picking up only a few pan
bolts at the front of the engine will be required as most of the
load is out near the center of the engine.
Brilliant way of getting around the water pump.
