I currently have Lectic Limited reproduction spark plug wires with carbon cores. I'm having problems with them and and wonder what other options I have. Are the copper core, etc that much better than the carbon core ones for performance? What about noise suppression for the radio? Too bad Lectric Limted or someone else doesn't offer reproduction plug wires with newer technology.
Thanks for your input.
I had problems with those wires as well on my 72 LT-1, they seemed to be very fragile. I went with some run of the mill Delco wires and have had no issues, including radio noise.
I agree with Mel's recommendation, but I've also used these Taylor wires on a number of small block Chevy's as well. They are 8mm, but I've never encountered any problems getting them under the factory shielding or through the 4-hole loom where they go under the distributor shielding. They also use a silicone inner and outer jacket like most hi-performance wires. https://www.summitracing.com/parts/tay-73051
They're considered universal, so they require that you cut them to length and add the distributor/terminal end. This makes them easier to install (especially behind the motor mount) if you're using factory shielding.
I like to start with the longest wire (at the spark plug end) and run them one at a time through/behind the factory shielding and stick them into the distributor cap without cutting them. Once they are all run and you are sure they fit correctly on the lower part of the engine, I cut them one at a time and insert the end through the boot (a bit of silicone spray on the boot makes them go together easier) and then crimp the ends on.
I remember running the old solid core wires back in the day, and once I got caught at a light side by side with the police, he pulled me over and wrote me for everything, as my header mufflers were pretty blown out, and he got instant static from my ignition system on his radio, especially when I tried to pull away gently from the light. He waited so he could drop in behind me and light me up! Those were the old L88 Orange wires.

I seem to recall buying the orange, solid core, Autolite wire back then on a 25 foot spool along with all the components and building a complete set for just about any engine. These were some of the first silicone wires widely available that addressed the issue with normal wires getting baked and then cracking when they were too close to or touched headers.
