I just installed a Pertronix with the magnetic ring in my 427. Previous to install with points I had an after market coil that read 0.8 ohms and I also used a ballast resistor. Pertronix requires a 1.5 ohm resistance coil minimum. So I followed directions using another after market coil with 1.5 ohms still with ballast resistor.
My question is the final output to the plugs any different between the two coils based on the initial wound ohm reading or is it only in the secondary windings? or combination? Should I use a lower resistance ballast resistor from a 63? Also does the older Pertronix adjust dwell with RPM?
