Denny, here's what a local engine rebuilder told me ( although the above advice is good as well ). Coat the engine with WD40. Remember that's WaterDisplacement40. Now that was for an L88 shortblock I have. I can't see why running oil down the carb just before you shut her off is a bad idea. Tens of thousands of boat owners do it every year.With an exposed cyl wall, he recommended WD.

And most importantly, do not store it on a concrete floor. Build or rig something to keep that motor up off the floor. I'm just about to splurge on a $55 engine dolly from Summit for long term storage of a stock 396. I'll be paying attention to your post for good ideas as well. Thnx for asking the question!
