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.
Paint it. Everything. Prep the block like you would for maximum adhesion. Oven cleaner works well. Dry, wipe and dust spray immediately. Paint all your machined surfaces. Rust o leom. When you're ready to build it. The paint is easily removed from the machined surfaces with lacquer thinner or brake cleaner...
