Cover it liberally with Marvels Mystery Oil, not only will it protect it from rust but it works great at cleaning any residual gunk off too (much better than WD40). I would also cover it with a plastic bag and store it so the block is not electrically grounded (on a thick rubber mat).

All I do is wipe all the bare surfaces down w/motor oil, then bag the parts. If the crank is going to be installed, use assembly lube on the bearings and journals- but I wouldn't install the crank until I was ready to do the mock up or final assembly instead of setting the crank in now w/assembly lube.

You will want to watch out for condensation unless it's in a climate controlled space. I had stored parts in the trunk of an old Jetta, went back and things had rusted because of the condensation. Fortunately nothing like a crank or cam, rods, etc. were in there. Just iron intake, exhaust manifolds, things like that.

thats the first thing that came to mind was Marvel Mystery Oil but was not taking any chances with my once in a life time build thanks

OMG, I cranked up a rebuilt Harley TC88B over the weekend that had been preserved with Marvel Mystery Oil. The smoke! Yikes! The shop was gassed out.

The coffee tasted like MMO the rest of the day.

i used the spray u get at a marine dealership to spray inside outboard motors.. it klings to the surface... i use it every yr when i put the bucket away...

[yardman]

i dont care if it smokes as long as it wont harm anything.whats your thoughts on two stroke oil.

[delawarebill]

its engine storage spray... it klings to the cyl walls and other parts for winter storage..

You have an assembled short block, the very little amount that you will use will be wiped off when you continue with assembly. Burning any of this is not going to happen.

You need something that will prevent rust, will not run off for a couple months, and is cost effective, easy to buy, and easy to use.

MMO is all of that and helps clean it for further assembly as well. MANY people use motor oil or WD40, but they do not clean as well and WD40 needs constant reapplication.

Just about any oil type substance will work as you only have a few parts, not an engine. Hell, used motor oil will work if you don't mind having to clean everything a little more thoroughly prior to assembly.

I prefer MMO because it has worked well for me AND helps clean, but this isn't something you need to give a lot of thought to.

Oil it with either Marvel or motor oil, bag it, compress the air out as much as you can, and tie off the end. Could probably toss a few of those moisture eaters in the bag if you'd like.

Cover it until you're comfortable. It's much easier to clean oil residue off than to remove surface rust off a pretty motor.

I know how it feels to see a beautiful engine sitting there. When I built my stroker, I was almost sad when I realized this was the prettiest it would ever look.

FWIW, 2 stroke oil will also work. In fact I have used it in the past. I found it to work well when used to spray the surface rather than wipe it w/motor oil (like a bare unpainted cast iron block), it can be thinned w/mineral spirits for use in a spray bottle. Be careful of flame or sparks or ignition sources of any kind- the vapor is flammable. Put newspaper under and around it to keep the overspray off things.

We turned on the paint booth fans to suck the smoke out. We're too cheap to throw a pot of Starbucks out, we drank it MMO and all.

Wait till Jerry comes in next week to paint and discovers he has to degrease the paint booth, I think I already hear my mom calling.
