Arcing across coil terminals

Plugs are autolite 66, wires are 8mm “suppression” so I assume both are resistor?

Looks like my center wire was the culprit, tracked and has small cut in sheath under the boot.

The resistor plugs with suppression cables will decrease spark energy a significant amount.
 
Going through the autolite chart, they dont offer non-resistor plugs in the heat range I am using (66/3926, equivalent of 14 with champion). Is using suppression wires with these plugs a big enough deal it is going to negatively effect my ignition reliability?

I don't want to go chasing down a problem that doesn't exist, but that being said I have not been able to get HEI conversion to work with this set of wires. I have removed every other variable. I assumed that the fact they worked
fine with points had ruled them out as a possible culprit.
 
I = V/R, Ohms law. Proven to work. Make R double, going to have 1/2 current. I bought a set of resistor plugs to go with COP coils. Due to plug angles and exhaust manifold on 273, remote mounted coils using suppression cables. Spark tests were weak, went to regular plugs, great sparks.

Bought a set of autolight double platinums, from auto zone for brand x car. The insulators were grouted in not crimped. They spewed out yellow crap, heard of people having insulators blow out.

HEI blame that on wires .... no touching that.
 
Dug into some threads on resistor vs non resistor plugs. What a contentious subject. Non-resistor are very hard to find, to boot. If anyone has a good 5/8” socket, 14mm 3/4” reach plug in the 12/14(champ) or 5/6 (autolite) heat range, im all ears.
