Engine Storage Issues

Alright guys i know it has been a while sence i posted last and what not. But the question is what is the best way to store a never ran engine for a undermined amount of time. The reason i ask is that i have decided to join the navy and i am not sure where i am going to be stationed and i don't want my engine to rust out until i get back to work on it. Ideas, thoughts, comments really wanted from you old guys. It is a 69 340 out of a cuda.

later.
