Rebuilt Engine needs to site for 6-9 months
 

Guys
What’s the recommendation for a newly rebuilt (everything !)
It must sit for 6-9 months before installing as restoration of body continues
What should be done to keep fresh and no oxidation or damage
Thanks

6 months is nothing in the big scheme of things. If you're really worried about it, make sure that no moisture or critters get into the intake or exhaust by covering the openings with plastic and sealing with tape. Remember to take them off before first start, and as always, crank the engine over without ignition until you have oil pressure.

Thanks, should I shoot some oil into cylinders and hand turn every few weeks ?

You could consider using engine fogging oil. Should cling to the walls better than oil.

No, turning will wipe off the assembly lube.
You can remove the spark plugs and give it a quick shot of Quicksilver marine engine storage spray.

Hopefully whoever rebuilt it put the right lubes in the right places and it shouldn't be a big deal as long as the engine is properly stored until it's ready for use.
