Mostly guessing here ...
How's the air filter? Unless new, change it.
With a less than full gas tank, try it with the fuel cap loose. If better, then a tank venting problem (limiting fuel flow). Maybe change the fuel filter while you are at it.
Check the timing. And maybe a problem internal to the distributor (old days I would suspect sticky advance weights)? Look/listen for vacuum leaks.
Oxygen sensor(s) more than 60K old?
A plugging-up catalytic converter, maybe?
Plus I'm sure many other things ... good luck!
