In preperation to put my 351c dual quad intake on my car, I am redoing the ignition.
My 351c currently has the stock distributor (points type, dual vacuum) and coil, but I can't seem to find the typical white ceramic ballast resistor in the circuit. Could it have an in wire harness resistor wire? And if so, how can I tell.
Since I'm doing my 351c in FE dress, (got the pent roof valve cover and adapter on the pass side and will do the drivers side today) I am using period correct plug wiring, a yellow top coil and a new distributor and wondered what ballast resistor (value?) to use. I have a period correct white ceramic balast resistor I would like to use.
Any idea's or help would be appreciated.
