Correct spark plug wires

Re: Correct spark plug wires

I changed the wires on my 67 and used the NAPA Beldon premium set. The wires are 7mm and very well made, the resistance is approx. 3000ohm/ft.

Harry, I have a old spool of 7mm wire, are you saying this wire does not go bad sitting ini the spool, I was going to throw it away.

Tim, from the research I've done it should perform like new. I have a 100 ft spool of 4Q62 wire that has no cracks and is still subtle after all these years. I'm just looking for several sets of ends to build a few sets of wires.

Hi Tim,

Wire doesn't go bad unless it is stressed (mechanical fatigue or over current). Or the insulation disintegrates. I suspect your spool of wire is just fine!

Re: Correct spark plug wires

Heat is what degrades the elastomeric insulation, so the shelf life of the wire if stored at room temperature should be indefinite, and as Joe said, the spool of wire is likely as good today as the day it was manufactured.

Don't throw it away!

Re: Correct spark plug wires

This post came along in a timely manner, thanks for that information This spool was bought at a AC Delco dealer that overhauls electrical parts like alternators etc. and it's a off brand that they must have used to either sell or make wires.

Harry, I could use a few feet of that 4 Q 62 wire for my 63 if your interested. My car was built second week November so it would work. Biggest issue I see is installing the ends properly.

Bill, You know you're right, but what about sets made with today's Packard wire ( which is vastly superior to the old TVRS wire)?
