Hi fellows,

I am looking for a source of engineering data on the Lord or Barry

mounts

for the engine.   I need technical information, plus the dimensions.   I
have checked the Barry website, but to my surprise they dont seem to

give

technical specs.

Does anyone know where I can find this stuff?

RV8 - 13b engine installation.

And some more. Can also be used in a composite firewall design.
Not to worry the 1/2 inch bolt can take the momentary bending loads
but the welding cup must be supported by parallel tubes
with the firewall as shown in this Perry Mick implementation.

Group,
I am very interested in the mount discussion as I want to fabricate my

Cozy

MK4 mount. I see a couple of way that it has been done and would like to
take advantage of what folks have learned as I construct mine.

Here is another very good  implementation that uses a steel cross beam under
the back of the engine to hold the Barry rubber mounts by Bill Schertz.
The steel cross bar fits just behind the oil pan aft vertical
panel. At the top in this jpg.

Group,
Trying  to sort thru the different approaches to hang the 13B from the
firewall. Could we have a discussion on the pros and cons of the attachment
points to the engine/firewall. Looks to me like there might be 3 general
methods. Tracy's oil pan/plate sandwich, crossbar under the flywheel and
some combination of existing cast in mounting points. Also, discuss the
pros/cons of cushioned firewall attachments vs. solid.

Thanks
