Posting as general reference material... Spark Plugs general reference site...
(Moderators, pls. edit subject title and/or move as deemed appropriate?)
I came across this while looking for AC chart mentioned in another thread, sooner or later this may be helpful to somebody...
The chart I was originally seeking (AC/Delco numbering system) is at: https://assets.sparkplugs.com/lc/ac%20numbering%20system.jpg
Here's another link to reference material for multiple manufacturers: https://www.sparkplugs.com/learning-center/5-charts-tools
The host site ( https://www.sparkplugs.com/ ) appears to be kind-of a "Spark Plug University" of sorts... Connoisseurs can just go plumb crazy, there's lots more if you navigate back up the path. Some of it appears pretty basic 'driver's ed.' stuff but there's also a lot of tech reference, etc... ENJOY!
Links are current as-of Nov. 2022 and may change (that's how I found this to begin with)...
