Where can I buy GM non HEI plug wires?

[COPO427]

No sparks jumping in the dark. I tried 3 different coils and have 9 volts at the + side of the coil to GND with the engine idling, and when I increase the RPM, the volts increase. Also my mechanical advance is working with the timing light. A delco plug wires tester says their all in the ok green zone, but I think it's just checking for breaks or large resistance.

Another tester I have looks like this guys and if I have it set between the plug and wire and set the dial to 30,000v I get no spark. But at 20,000v I do, so that's weak. Also with another tester that I touch the wire with and the tester should glow if the spark is strong, I see a weak light and hardly any at some boots. I also did the test with the plug wire set on the exhaust manifold to see how strong the jump is. It's not great. So I need a set of wire and hope that's the problem. My Taylor Spiro Pro wires are over 10 yrs old.

Last week I could hit 6,000 rpm in 1,2,3 before letting off.

Found this, are these good wires?http://www.lectriclimited.com/spark_...production.htm
