Hi All,
With all the hoopla and hype out there concerning plug wires, I thought I bounce it off this forum for some input.
I've got a custom 460 in my '78 F350 4x2. Mild cam, 9.5:1 compression, headers, Duraspark, Mallory canister-type coil.
I have some Motorsport 8mm wires that are at least 7 years old. I measured the impedence at 2.3-2.7 kohms. Now I'm reading about resistor wires with only 50 ohms per foot!
I don't need to spend a passel of money, I just want something that's not overkill and reasonable for a real-life application: hauling/towing.
The Motorcraft wires seem to be good for at least 100,000 miles. It is a wide spark plug gap that can cause excessive secondary voltages that break down wires etc. If you replace the plugs or at least re-gap them every 50K it seems to make wires last well.
Anyone tried the Nology wires? price is out of this world but you never know. Mallory has a few interesting articles on their website that talk about low voltage resistance and what manufacturers dont tell you. Cant remember the specifics I'm afraid, but worth searching out.
Not with a Ford, but a friend has a 69 Firebird drag car that he couldn't figure out why it missed, then out of desperation, he changed from Moroso Blue Max wires to the fat Taylor wires and he has never looked back. He claims they fixed his problems, but that might be hard to back up.
I have a built 71 400 ,I prefer the MSD wires,but my whole system is MSD,btw,some aftermarket ignitions call for a specific conductor in the wire for it to work properly...
the resistance in your plug wires means its ability to carry voltage efficiently,ie;when you get down to 0 ohms,your wire is broken,so,the more ohms the better the wire!

Turn that around. 0 ohms is maximum conductivity, and delivers more amperage, which is not necessary to deliver an adequate spark. The more amperage, the more radio noise is emitted. Somewhere there is a happy medium, which is what I was inquiring about. More ohms=more resistance, so at some point as you increase resistance, no spark will be delivered.
fastford59, sorry to correct you but the lowest resistance wire is the best to conduct spark energy to the plugs, (not counting for interference on radios and puter) your 180 degrees of on your thinking. Real high resistance like Meg ohms is next to infinity. With carbon string wires years ago they had motors start missing due to the carbon wires going into high resistance over time reducing spark energy to the plugs.
