Well its going to be in an enclosed trailer. May be tough to get it on jack stands.

Swap out the wheels/tires for some street tires and pull it in.

Make sure everything is all lubed up, joints etc before hand.

I would keep anti freeze in it. Personally..... because you drain it, you still have moisture in the block. yes it wont crack but it could rust - it will rust. Then you will have it all in your system later.

I like the idea of pumping some gas/oil mix through the fuel system. Pull the carb, drain it, lube it and wrap it in plastic bag on the shelf.

Doesnt really matter what you do with the rear slicks, they will be junk if they arent used for an extended period of time. Oils dry out and they dont work as designed.
