New Ignition
There is not a great deal of merit in performance ignition. The money goes a LOT farther with items like carburetors, intakes and exhaust. For a specific plug gap, there's a certain range of secondary voltage that it takes for the spark to jump. The factory Duraspark setup does that just fine. All the science around fancy terms like "double-sparking" or "capacitive discharge" does not really net you much on stock or mild motors in my honest opinion.
To answer your actual question, though, it depends how much you want to spend. You can get ignition modules that are compatible with the Ford hall effect sensor in the distributor. You can also get completely new setups that have a new distributor and module (in some cases the module is part of the distributor).
A cheap and quick upgrade that many misinformed people do is to buy a "performance" or "hot" coil and use it with an otherwise stock ignition. The power transistor in the Duraspark module is rated to handle the current drawn by the stock setup. A "performance" coil with lower primary winding resistance can strain the module, and there's hardly any difference in performance in the first place.
