Chris, you have two concerns, not just one:
1. Lack of oil: a common practice when an engine has not run for a
long time, or has just been overhauled, is to "motorize" the engine.
That is, keep cranking the starter motor with the spark plugs out until
you get oil pressure (with normal aviation oil). By having the spark
plugs out you have no compression, so the starter is not working hard,
you're not putting pressure on the bearings and wrist pins, and should
not wear down the battery. When you do have oil pressure replace the
spark plugs and try to start the engine.
2. Probably more important, even though it's been stored in a "dry"
environment, there is always moisture in the air, and with temperature
changes, moisture will condense on cooler surfaces (metal). Rust can
form. I recommend pulling one cylinder and looking inside the case with
a flashlight and mirror to see if any rust is present on the steel
surfaces. Rust acts like sand. You may need to have the engine torn down.

Hello everyone,
I have a 415C that had its C75/85 majored in 1982. It
was installed on the airplane with a new prop. It was
Never turned over and not really 'pickled'. It was
stored inside in a dry environment.
What should I do to commission this engine? Any bets
on it being okay? The only advice I have received so
far is to squirt some Marvel Mystery Oil in each
cylinder, wait a couple days and fire it up.
Has anyone ever considered pressurizing the line going
to the oil pressure gage? In other words, I would rig
an accumulator that I could pressurize with air that
would then pressurize the oil line with oil (maybe
using a really thin oil). Could I assume, after a
couple days, the oil would work its way through the
engine and have a positive effect?
Thanks in advance, what a great group!
