STORING A FRESH BLOCK

Hi Folks

Any suggestions for extended storage of a fresh 340 block? Block has been bored and honed to.040, new cam bearings, square decked, and the crank ground 10/10. The engine will not be needed for a year or so, and I am a little reluctant to build it and let it sit completed. Looking for some input on how best to store it while avoiding rust. What say ye all? Thanks.

EDIT: Th machine shop advised not to wrap it in plastic as it will condense inside. He wiped the fresh machining with engine oil, but I doubt that will last long term.
