Ok, so I'm getting tired of searching for the ever dwindling supply of AC44 plugs. After arguing with the kid at the local parts store about the existince of a 322ci motor (man, what do they teach kids in auto shop these days..they know about nothing but SBC's) and finally just "borrowing" the appropriate page of their cross reference manual I noticed that it listed several alternatives:
ACR43, ACR43S as well as Champion 58S.
So my question is this- Whats the difference in these plugs, is it heat range only? Or is there something that would prohibit me from using them
