Resistance will vary with the length of the wire but around 500 ohms per foot. You have to be careful with aftermarket parts like ignition wires and running non AC Delco parts on the 3400 engine. These engines run best with AC Delco ignition wires and AC Delco or NGK spark plugs. My second choice for wires is the Taylor Spiro Pro 8mm. Some owners have experienced problems with the Bosch plugs not at initial installation but later on.
We run NGK TR55IX Iridium spark plugs and the Taylor hp wires.
