Well, sadly, about the worst thing you can do is just let one sit. My counsel was going to be -- start it up and run it every few weeks, but you're way past that now. After 10 years of sitting - almost any system that has any kind of fluid in it has the potential to have problems -- especially fuel and brake systems. Old seals and gaskets dry out, etc.

If you simply want to be sure it will turn over, won't hurt to fog the cylinders with WD40 and put a ratchet on the crank pulley. But letting any vehicle sit that long is just asking for trouble. I have two hot rods -- get them out once a week for at least a 20 minute drive. Oil changes at least once a year, and all the rest of the fluids (power steering, brake, coolant, tranny, rearend) changed every 3 years.
