As for the Lyc 360 - wouldn't have any idea, let us know what you come up
with.


I did Net search for Lycoming O320 and O360 weights...

At the eracer list [http://listproc.eracer.org/eracerlist/msg00263.html]
I found:


The consensus is that the Franklin is about 30 lbs heavier than the O-360
Lycoming and about the same weight as the IO-360 Lycoming.

The O-360s and the Franklin would be heavier than the O-320.


OK, here is the Franklin info:
 Dry weight: 330 lbs.
includes fuel pump, 2 magnetos, starter and alternator.


>From this, we might conclude that an IO360 weighs about 330 lbs and an
O360 weighs about 300 lbs

 

I also found http://www.isd.net/eulmer/weights.txt from which I
cut'n'paste the following:

    IO-360-B1B          180      295     0.61

No mention of whether this includes oil, accessories, etc.

>From Lycoming's page http://www.lycoming.textron.com/engines/360.html.
That has an image :-( of a table which says
Model           Dry Weight
(L)O-360-A      265
O-360-F         270
IO-360-B        270
IO-360-A, C     293
LIO-360-C       306
TO-360-C, F     343
TIO-360-C       348

No mention of what accessories are included. I guess you could add
10 lbs??? of oil to get a weight comparable to a 13B.
