I also use the solid core wires but have to change back to the old carbon
core to tune it because of the interference on my dwell and tach meter. I
was surprised by just how much interference they put out. The only carbon
core wire I have had go out was too close to the header. I use Taylor wires
and both kinds are quality made so if you use any type of electronics in the
car I would suggest using the shielded core wire. For performance solid
core is the way to get the most spark.

Subject: [Healeys] New Plug Wires makes the car GO!
Finally, after years of putting up with engine misses above 3000 rpm,
I've installed new plug wires--
metal core, with NGK plug caps.
Currently using NGK plugs in the Denis Welch head.
I've heard many times that the graphite core wire breaks down,
etc--maybe that is true.
Still using the threaded distributor cap and coil. Thanks to Randy at
British Heritage Motorsports for the advice.
