Performance wires are usually in the 300-400ohm range.I got some "MegaFires" that are in the 200ohm range. That is the lowest I could find. If the wires are made for your car. I doubt they are to high.

I read them, may not have been the right settings, I had numbers around 2.3 to 2.6, does that sound good, they are the Ford Racing 9mm wires. thanks again

maybe thats 230 - 260 ?

MSD 8.5's are 40-50 oms per foot, the ford 9mm's should be similar i would imagine. so thats like 4 feet long wire to have that amount..... sound about right?

My FRPP wires had a much higher resistance than my MSD superconductors do.... It really won't make much/any difference in your performance. I'm going w/ Taylor's next time though.
