MSD or Blue Streak wires?

The best wires I ever used on a factory 340 were Packard wires. They fit perfect and were burn proof. Also Mallory wires were good on BB mopars

For use with Performance high energy ignition I like MSD wires. Blue streak can't take the engine compartment heat very long. On damp mornings in the dark Blue streak wires look like a 3 ring circus of sparks jumping under the hood. Just my experience with them on several applications over the years. I can remember using Belden wires years back. Cheap and lasted about 1 year.

If using a standard coil this information is not applicable. I was always using Accel or some type of High energy coil years ago. Both my big block 440 R/T's came with Mallory dual point ignitions, wires and coils from the factory when bought new.
