These ?

If so , what I can tell you is that they are CARBON CORE wires - Not that there is anything wrong with that , however I can state for a fact they are very very high ohm resistance

I had been running a set on my 383/432 Stroker for a few years now - They look great and even fit better then expected , but when it came to inconsistent RPM’s , especially higher , I was chasing my ass between ignition coils and ECU s , even fuel pressure , just couldn’t put my finger on it because it was so inconsistent

So this past month after getting my car out of storage , the first few drives on the street I just wasn’t happy

Pulled the plugs , wires , and compression test AGAIN , just looking everything over while I had time on my side

I couldn’t believe the ohm resistance on these wires when I tested them used , and even against another new set that I have here in the bag

The longest wire #7 was in excess of 20,000 Ohms brand new

OK

So last month I put on a new set of Pertronix 7mm SPIRAL CORE wires set up for a big block

I wanted to use the factory spark plug wire holders

The longest wire #7 had less then 2,000 Ohms


Beyond happy with the fit (A little long on some) , looks and PERFORMANCE difference - Night and day honestly


Picture is my old set up last year with those date coded wires



Now running a Pertronix coil that I installed last year chasing my ass , ballast resistor is bypassed on the back side - Pertronix 7mm Spark Plug wires - Same distributor - Same Mopar Chrome ECU that I have had like forever

Only thing that I changed this spring was those plug wires - Difference maker
