I don't know where you are in Oklahoma, but you are right. It's hot and humid right now. I live just south of Tulsa. Filling the block now I'm afraid would make the cylinders out of round. I only commented about the dry block with alcohol working for people, but I have to say that I would be pulling this engine and fixing things right. That said it is your engine and you can do as you please. I do understand the frustration and thinking about putting all that work in right now in the heat. Do you run at Tulsa or Nobile?
