Could be fuel starvation (weak pump/clogged line/clogged fuel filter/ junk in carb) does it stutter in every gear at that rpm?

Try a full tune up of plugs, wires, points, condenser and new distributor cap if not previously been upgraded. Worth the upgrade even if the symptoms are still there. Go for the above suggestions... fuel filter is a real suspect.
