Peter,
Didn't you mean some like:

IO-360    320.4 lbs    24.2 inches from firewall.
I0-540    396.4 lbs    28.2 inches from firewall.
FRANKLIN  318.4 lbs    24.4 inches from firewall.
MAZDA     430.2 lbs    19.4 inches from firewall.
CHEV V6 Alum block
etc, etc

In other words the weight of the engine and the c.g. of the engine from
the firewall. The empty weight of the plane depends on a lot more things
than the weight of the engine. I think your interested on knowing the
effect of hanging different engines on the same plane.
