1946 Pickup Pertronix ignition
I put in a pertronix ignition (1285LSP6) in my dad’s 1946 Ford pickup flathead V8. It ran smooth at an idle, but when I bring the RPM’s up it stumbles terribly. I spoke with Pertronix and they asked about my plug wires. They said I need to change the plug wires. The pertronix ignition can’t use solid core plug wires which is what is OEM.
Has anyone converted this kind of vehicle to an electronic ignition successfully? Did you find an issue like mine? If so, what plug wires do I need and where did you find them?
Many thanks in advance!

You need suppression type wires. They're available from many sources, like Speedway for one.

I did eliminate/bypass the ignition resistor under the dash, as it is no longer needed with the conversion. I'm using the stock ignition coil, along with the stock cloth woven ignition wires, with open connection at the plug (no insulated boot)
It starts and runs better than it ever has. I put about a hundred miles on the car so far, without any issues.
If your running the stock coil, I'm not sure why you would need to change the ignition wires, as the high voltage out of the coil to the plugs will be exactly the same as before the conversion. The electronic igniter is just replacing the mechanical points, that tells the ignition coil when to fire.
Did you switch and install a hotter firing coil?

Pertronix sez don't use solid core plug wires with their Ignitor. Anecdotally at least lots of people claim to use the Ignitor 1 module and solid core wires with no problems. I've also read people say to avoid resistor spark plugs and radio suppression plug wires in a 6 volt system.
