Hi
I just took out the points and put in a Mallory Espark conversion on my 1972 Plymouth 318 and also picked up a Msd blaster 2 coil. When reading the instructions they told me to use a 0.8 resistor inline with the stock 2 pin resistor that was on the car.This to me did not sound right so I called the 1800 number and they told me to do it this way and not to run a new key hot wire to the Msd resistor and then to the coil(what I was going to do).I have looked around and seen all different answers from all different post in forums by other people. This forum has been good to me its like my little haven, so I must ask what is the best way to do this?
thanks

 

MSD knows what they are talking about and have years of experience with there product, I use MSD and followed their instructions and it has never failed me I know that to you and I it does not make sence but it works

 

Is the MSD blaster a generic 12volt coil, or was it a special number for a Mopar? Mopes use the ballast resistor to drop the voltage down to 7-8 volts at the + side of the coil, MSD for a MOPAR might want a tad less.
