How long can a new rotating assembly sit

[blackgn1]

I'm throwing around the idea of starting a new engine build. How long can a new rotating assembly sit in the block? Just the block with the new assembly installed. No heads, cam, ect.

forever, as long as you keep the moisture and critters out.

I have read where engines have sat for years. Cylinders kept oiled and dry. Wrapped in engine bags.

Spray it with WD40 if it's all cleaned up already and bag it. Should be good indefinitely. I know a guy who stores old, unrestored motorcycles this way but without the bag. You just clean the oil residue off, which can be tough to get it all, easy with a hot tank on on engine though, and you're back in business when you get ready for machining.
