Just for fun, I found an online X-reference for spark plugs and got the cross for the ONLY plug listed in the Shop Manual for my '54 Clipper 327: Champion J8
At the top of the list was AC Delco 45
So, other than "R" or no "R" I guess I'll quit worrying about it and put the same kind of plug in as the ones that were there when I bought it.
Notice, the cross ref wasn't for an "R" 45, so I guess the J8 was not a resistor type plug?
Now, how do I tell again if I've got "resistor" wiring???
(Own Dyneto seemed to have some expertise on this, but nothing on identifying the wiring as resistor or non-resistor)
The suggested Gap in the shop manual is .023-.028. Should I shoot for the wider or narrower initial gap, or doesn't it make much difference?
My seat-of-the-pants rule of thumb is to set for narrowest initially, as the gap will naturally tend to widen (unless there's fouling) as the plug is used.
I don't know if this X-ref will kindle warmth in anyone's heart, but here's a link:

Others on this fine site probably have much more expertise when it comes to spark plugs for Packards.
