Stop in for a cup of coffee

Getting ready to delve into the 273. Keeping it fairly stock, maybe a couple of bolt-ons. What is the "minimum" effort you would go with and check? Target is to (conjuring up RRR) "get it runnin' and drivin' "
What does it need? How long since it has been run? I got mine running for a couple years with a good tune up and new fuel system but the car had set for years. It was weak though.
