I was working on my car today and noticed that the spark plugs are Champion W-14 these were in the car when I got it are these the right plugs for this motor? It is a 14-L motor with a 15-L head.

The W-14 is fine, although I think it has been replaced by another plug.
I prefer the Autolite 3016 for my 14L with 15L head.

Orig approved plugs for 60, 63, 66, 70 was Champion C7 .. Lots of hits in search for replacement plugs.

Champion C-7 spark plug replacement
C7 was discontinued & replaced by Champion 541 / RD16 which is a resistor type spark plug. D16 was non resistor equivalent.

Autolite 385 would be a colder plug than RD16 Champion.

Autolite 386 resistor plug same heat range as Champion RD16.

Autolite 388 resistor plug hotter same heat range as Champion D21.

If you want a non resistor type plug use Autolite 3116 or Denso L14-U.


NAPA as Rick said has plugs replacement plugs.
