May be a southern thing, but we call high voltage coil output "high tension". About 20 years ago shocked ever living mess out of myself on a cracked spark plug wire. Will never forget the thrill. Have approached ignition systems cautiously since. Am absolutely fastidious with the wires, a task made easier with Autozone/Advance lifetime warranties. But to be honest, my BIGGEST fear when timing the Fords is catching myself on a fan or belts...
