What are your thoughts on spark plug  wires.
Solid core or carbon coated.
I have a 78 with a 425.
What do you guys feel is the best wire.

ROY!  I strongly suggest you purchase plug wires made in America made by "STANDARD"  which makes many good high quality automotive parts. I always had them for my 76 Coupe de Ville and they fire very well and last a long time. Buy American wherever you can because they are of much better quality and not much more costly at all. Check your area auto parts stores or go on line.  EAM

Roy,

A long time ago I changed my 61 CDV and 68 ELDO spark plug wires to solid core and my plugs to resistor.  One reason for that was the resistor wires were made with graphite coated string instead of wire.  If you pull the wire incorrectly you can break the string greatly increasing the resistance in that wire. 

Being in the electronics field I also had issues with the difference in resistance to each cylinder caused by the difference in wire length. 

The solid core wires I bought are also silicone insulated.  They were expensive but I have never had any problems with them and ran them in my daily driver for at least 20 years.

Thanks for the responses. I have been reading about the different wires and it seems the hot rod guys like the low resistance solid wires, like MSD makes.
Just wanted to know how many guys use the different type wires.
What brand were yours Glen.

I really don’t know.  I bought them from NAPA about 25 years ago.  IIRC it cost me $58 for the set.  Very expensive for the time.

The wire in the premium Napa sets is Belden wire.  I have had some on for 10 years now and they still seem fine.  They are also have a fairly hard shiny outer coating on them so they also still look good after 10 years.  They are also blue which at least somewhat fits with the blue valve covers on the later Cadillacs.

Don't solid core wires give you a lot static on the radio?

The MSD wires are not suppose to do that. They have the low resistance but enough not to bother the radio.
Just poking around here to find out if anybody uses them , or if they stay with the high resistance wires.
I have a set on my car from NAPA, and they seem OK. Just wondering if the low resistance are better.

That’s why you use resistor spark plugs.
