While I have found their ingition systems to be very reliable, Fords generally don't have a dropping resistor before the coil, Voltage is just lost across the crappy wires, and the fusable link in that circuit. And nothing to boost voltage during cranking.... That is a Dodge circuit. And if you have old condensor, use it. I never changed my condensor, just the points.... If you have points problems, especially if the dwell drifts, then you may need a new breaker plate. Its where the points get attached, this fails in higher milage fords with points.....(80,000mi+) Go get a NOS points and Cond. off ebay, then only change the Condensor if you know its bad. (serious point damage in short miles) Generally, the Cap absorbs the noise from the points, for the radio, and absorbs the return from the collapsing field from the coil making the spark. So for that reason, if yer gunna replace it with a store cap, the voltage should be high.... 1000V, able to opperate at 300F. Since there is not much of a demand for points anymore, I would assume, they don't care much about quality anymore....
You are not alone........
