Packard Wires Application?

[dannystarr]

Found a set of 8, plus coil wire, of used spark plug wires. The only printing on them is Packard   440   USA. Anyone know the applications{s}?.. Thanx.. Danny

AFAIK, it wasn't OE but hi-performance aftermarket wire sold by the roll or by the foot, from which you made up your plug wires to suit the application.

Yeah, I think it was usually aftermarket due to no EMI suppression.  So you can listen to your engine rev in the radio speaker ( and so can the radios in cars around you)!
