I just watched this video. He ran the wires through metal tubes (I think) and I was told to keep my spark plug wires away from metal or they will arc. Maybe the tubes he slides them through look like metal but they are plastic ?
Keep in mind, the only part of a plug wire that is "live" is the 2mm black core in the center. In Taylor wires, its a single strand of copper wire. The rest of the wire is all insulation to prevent the current from getting out. If there is any "leak" in the outer core of the wire, it is garbage. The flat rate way to test wires used to be a spray bottle of salt water. A quick spritz would quickly show any problem areas. The tubes in the video are stainless steel but in theory, you should be able to run a good plug wire completely underwater without causing a misfire. Its still a good idea to keep wires away from metal as they can get damaged from abrasion and lower quality wires can create an inductive crossfire if they are routed too close together. If memory serves, the small block Fords were known for that problem between cylinders 7/8 at high RPM. As a footnote, I've never been able to witness any power increase just from changing wires. I've seen lots of videos claiming a 10hp increase but unless a plug wire is actually shorting out, I'm yet to see a significant change.

You are running Taylor wires. They are the best. Forget the tubes, just get a nice set of looms that will keep the wires away from heat and chaffing metal.

I agree that Taylor make a quality product but its important to choose the correct wire for the application. The ultra low resistance wires, coupled with a wide spark plug gap can really drive the coil hard. HEI cars are particularly sensitive as the coils don't disperse the extra heat well. Ok for a quick run down the strip but if you are stuck in a traffic jam at idle the poor coil won't last long!
