I have an 83 monte. First thing in the morning two pums on the gas pedal and it fires right up. Once it gets warmed up, doesn't mater if I go 1 or 100 miles, If I shut it off for any reason, when I go to start it any time within a minute to a couple hours it acts like the battery is low and it is really hard to start. It is a 305 with a 4-barrel. The only change I did from the get go is, after I fried the distributor, I put in a vaccuum advance distributor.
