Not really. When I had to cold store, I used to lift the toys and place them on 12 x 12 inch wooden blocks placed under the frames at suitable points and then used aluminum plating as a shim between the wood and the steel. The point was to unload the suspension and keep the springs happy. I'd also remove the batteries and bring them in for my battery Christmas tree stack. For the van i went out and bought a Canton Racing pre-oiler reservoir like the drag rides use and plumbed that in so I could pre-oil/pressurize the motor before I tried to crank it. Seemed to do the trick and it is still in residence because the van doesn't get as much use as my other toys. I also bit the bullet and acquired proper covers for both vehicles. You can throw a tarp over your ride but if you have a good heavy padded cover underneath that tarp your finish will thank you.
The Monte, because it is sitting in Bay Two and still half apart, does not have its distributor installed. Instead I have a dummy drive that lets me put a 1/2 inch drill motor on it and periodically prime the oil system. It will likely get a pre-oiler of its own just as a safety precaution. If you can run your motor and warm it up, it does help but, as noted, you have to take precautions on account of the critters who love places they can get warm or climb up into to stash things. Popped the hood on my Ma's Caddie one spring and found that one of the local squirrels had tried to use the engine as a stash. Fortunately I had plugged the snorkel on the air cleaner against just that possibility but it was still a mess to clean up. Little bugger never did come back for its acorns!!! The neighbors cat periodically tries to hide under my truck, usually just after I have returned from running errands, because there is still some warmth coming off the oil pan even when it is cold.
