Frank,

I am using the Magnacor wires on my '80 SC. So far they have performed extremely well. They are not cheap, but I think this is a case of "you get what you pay for"! You can tell if the old wires are cross firing or arcing to ground by looking in the engine compartment at night, preferably in a dark area. Any arcing will show up as mini lightning bolts that are blue-white in color.
