Assuming the 460 ignition is same as 560 the resistor may serve another purpose in addition for voltage drop from 12 to 6 volts.
Looking at Bob M diagram for a 560 (do a search, they are often referred to on this site) there is a wire from junction of coil/resistor going to an "I" terminal on the start solenoid. This bypasses the resistor when cranking to give a hotter starting spark.
If the resistor is open the engine will start and then die when starter is released.
(I"ve seen this setup on vehicles and tractors of different colors. I believe this is the reason for coils labeled "12 volt external resistor required")
