I have a 71 GMC that sat since 1986. It was running in 1991 but the brakes didn't work so it sat until 2004 when I finally talked the owner out of it. I redid the brakes and cleaned the tank, new fuel filters and fuel lines, oil change and oil/air filter, plugs and wires, anitfreeze and hoses, tires and wiring/ground checks. I cleaned the points and primed the carb. It started and idled like it ran the day before. The truck was only used to go camping with and only had 49K miles on it. The bed boards are still in factory paint.
