Oh ****, Mr Fuggin Do Right Wilson !!! And I thought I was picky cuz I like #1 on the cap where it's supposed to be. Figured so long as I got that, the wires aren't touching metal or the exhaust manifolds, I'm good to go. I also try to keep wires as far from exhaust manifolds as possible. They don't have to be right on a manifold to get very warm and cook your carbon in the wire to where it's stiff like a pencil led then when those leds break, guess what? Failed wire in short order. The Arc will still jump and travel, but with every break, it's weaker and weaker spark. This is usually the killer on plug wires, is the heat, carbon gets stiff, then you move a wire to change plugs and now it's got a bunch of broken stiff carbon. So keep them off the heat as far as you can.
I ended up running real braided wire cores in my 64 GMC. Stereo sounded like **** badly. Didn't much care cuz you couldn't hear it over the motor anyway, and only time I listened to the stereo was when I was parked and motor was off hanging out at the street races or with some chick gettin' toe up on the seat or in the back down in the river bed or Azusa Canyon at East Fork.
