I store mine for about 4 mths out of the year. I keep gas in the tank with fuel stabilizer. Before I store it, I put the stab in and run it for a few minutes to get the stabilized fuel into the carb. Then I fog the engine with Dexron II. I then drop the
oil and filter and replace with new
oil and filter. When you are running it that last time, just before you drop the
oil, I run some Dexron in the crank case to flush out any sludge and it thins the oil a little so you get a better cleaning. I don't normally put it up on blocks, but if you are going to be gone a year+ you might want to put it up on stands. Might want to put a little Methyl Hydrate in the fuel to keep the moisture problem down to a minimum.

All thing considered, you can put together a pretty good argument that the 427 Cobra is the ultimate performance car, judged on any basis you want to name."
