Non-solid core spark plug wires for pertronix, How do you know Options

[bbrock]

In the home stretch toward first start of my engine and hit a snag. I think I have solid core wires which is a no-no with Pertronix. I bought this set in the 1980s (probably from Tweeks) and unscrewed the connector just to check and found this.



Those are copper strands, but does that mean this is a solid core wire? The coil wire is labeled "suppressor cable" and looks to be carbon, but the plug wires are not labeled as such.

If I need to buy another set of wires, how do I know what I am getting? Karlyn/STI makes a wire set with all short connectors that would be preferred for my carb setup, but their description is vague:

Product Features

- Unique Tinned Copper Core
- Greatly Exceeds O E and Competitor Specifications
- Double Extruded Silicon-Over-Silicone Wire
- Contains 19 Strands Of Tinned Copper Core
- Super Conductivity w/Superior Corrosion Resistance
- Limited Lifetime Warranty

What wires are people running with their Pertronix Ignitor II or III? Apparently the Ignitor I isn't as sensitive to RFI/EMI as later models.

Brent...that wire is fine...that's stranded wire...solid would be like something you would use for a house electrical outlet....just one wire.
The Karlyn/STI wires are good with very nice connectors.

Do the STI wires have the terminations for the pertronix billet distributor male connections? Or what else might be suitable? Right now, the only option I see is to buy unterminated pertronix wires.

Based on help from another member, I wound up buying a set of Pertronix 704101 Flame-Thrower Black Custom Fit 4 Cylinder Spark Plug Wire. I cut the spark plug terminals off and screwed on the standard bake-lite terminals from my copper set. Worked great.

EDIT: Whoops, just noticed you need terminals for the billet dizzy. The ones I got won't work.

I always thought the point about not using "solid core" wire with electronics was that you need "suppressed" wire like MSD so you don't get the RFI noise. I wouldn't think simple stranded wire would be offer suppression?
