There were GM transitor ignition set ups but I do not think anyone repops them are the originals are unobtainable price wise.



Yes, correct very rare. This is why I did not mention them. I believe 'Most' were installed on Corvettes and some race versions. Weren't they also used on tach drive set ups(?).
Just another T/A fanatic. A new project in the works.

One way to compensate for the resistance in the car's primary wire is to buy a coil with less primary resistance eliminating any re-wiring.

The pertronix pickup needs to be used with the correct ignition coil resulting in the correct resistance in the primary circuit. A pertronix technician will be able to guide you in choosing the right coil.

If memory serves me, I had to replace a 3 ohm Mallory coil with a 1.5 ohm coil in my stock 68 but then my memory kinda sucks these days.
