Re: Spark plug wires, Packard 440 or Packard 330 or?

The publication "Copper Nerves" by GM's Packard Electric Cohttps://packardinfo.com/xoops/html/downloads/CopperNerves.pdf has a copyright date of 1938 and mentions Packard 440 as being the preferred wire over the older lacquered wires. I don't know for sure if Packard Motor Car Co used it in 42 since they did have a shiny black lacquered cover wire at least thru 47. I would imagine 440 was available for 42 though and Packard Motor may have had a different and lacquered outer covering over the wire instead of the softer dull all rubber that is usually found on todays 440. Since it is a proven product available at the time and easily available today I would probably go with that.

I didn't find a ready spec reference to Packard 330 wire so wonder where it falls in the lineup. The Steelductor box says it is used on 40-42 Packards but as I recall factory photos show the 42s with black wires.
