My dad just bought a standard run of the mill aftermarket white box HEI distributor, to replace the points distributor. nither 1 of us has ever done this swap, and I know to remove the ballast resistor ( where is that located?? ) and that new plug wires are needed because of the diffrent cap boots. where do we wire the hot lead to, the ign switch? also, what should we re gap the plugs to or should we get new plugs also?
