"Second Question about Pertronix Ignitions"
I finally received a Pertronix 1149c from Classics Garage and installed it yesterday. It does seem to make acceleration smoother, and it has allowed me to reduce my idle speed 250 rpm. Pretty cool!
I was about to install the flamethrower II that I purchased, when I read on the 1149C installation instructions that my coil should have no *less* than 3 ohms resistance. The Flamethrower II brags about its 0.6 ohms resistance.
I thought they went together, but now I'm afraid that I might let the smoke out of the 1149c if I use the new coil. Since they are not readily available, I don't really want to experiment.
Anyone have any input / warning / words of advice?

Hi David, Just to let you know that I used the 1149c with just the 'normal' coil for about two years without problem. I still use the normal coil even though I have changed my dizzy to a Lucas one with a different Pertronix unit. Stay with the normal one until proved otherwise.

Apparently the Pertronix needs a ballested coil. If your coil does not have an internal ballast resistance, you can install an external ballast resistor. You should be able to get one at your local auto parts store.
That sair, if the car is working well with the coil you have, why change. "If it ain't broke......"
Most Lucas and Bosche coils have a built-in ballast resistance.
