Paul,
Thanks a lot. This helps. In all of my options I have finally
decided that
it would be best to modify my present engine mount by cutting out the
diagonals, and the top and bottom horizontal cross braces and while
securing
the rear part of the engine mount have the front jacked outwards
about 3"
per side. New diagonals and cross pieces could then be weld in and
the whole
unit set out for heat treatment to relieve the stress. The present
dimensions of the engine attach points were designed with a rear mounted
Lyc. IO-540 in mind thus the pitch is presently only 15 3/4" wide by
17 3/4"
high on center. Height is OK for me, just, but width is to narrow to
make
any kind of sturdy bed mount.
Perry's design works for my 2nd gen test engine but not large oil
pan I am
thinking about. I am therefore leaning towards sandwiching a 1/4" thick
4130 steel plate between the engine and bell housing to catch the front
Barry mounts. On the pulley side mount I can use something coming off my
early front cover. A few ideas you have sent me before are food for
thought
though not exactly what I have in mind. Yours or anyone's thoughts
would be
appreciated.
Thanks
Doug Fir
Hard for me to comment without seeing a 3D. Rhino has me spoiled.
Do a hand 3 view sketch and scan it in. Or take a few side views and
front
views straight on of your stock motor mount. Also a top or bottom view.

BTW Doug the last thing you should design is the motor mount.
You need to make sure it clears everything. Either do a Rhino
3D or a Styrofoam mock of of everything. In particular the exhaust
as that is where people run afoul of the motor mount most often.

Doug,
If you want a Sea wind motor mount to cut up or try your experiments on, I
have one you can have that I was about to junk.
