The 522x series are listed in the books for the magnum 318 and
the 392x series are for the magnum 360. They are also listed
for a few other motors. This does not mean that you cannot
use the 392x series in a magnum 318. I have been using
the 3923s for the past few years for both strip and street
operations.
The 522x and 392x series are copper type plugs.
