Hi Steve and welcome to CHR.. Very good question and one that effects me two, not that I live in a cold country like Canada, but my 350 chevy has been sitting in my T without starting now for approximately one year while I finish body work. Before I stopped using it I had the 3 x2's carbs and the timing etc all tuned by a tuneshop,so I really do not want to take the dist. out to turn the oil pump mechanically. So lets hope we get some feed back to your question.
