For 42-48 the Ford ignition condenser size is 0.25-0.32 mf. The condenser is matched to the coil and allows it to develop maximum voltage output. Here is the kicker the coil usually does not put out maximum voltage, because it does not have to. It only puts out enough voltage to arc across the open circuits in the secondary. The open circuits are the gaps between the rotor and the cap, and the plug gap and any other high resistance. So keep the gaps small, use a new rotor and cap, nonresistance wires with soldered terminals and gap the plugs around 0.25 to 0.30 and use a plug that fires at low voltage. The coil may be able to fire at lower voltages than the Max. removing the Ford resistor will Lead to over heating the coil over time, and it is not necessary or desirable with a engine that is running properly. I use the NAPA FA66 condenser.
