Hello all... I used to post to this list a few years back. I still have the same car, a 1973 AMC Gremlin X. The car has been more or less sitting for years, and now I'm trying to put it back into semi-regular service. I have a quick question: Does anyone have a part number for spark plugs one heat range hotter than stock for a 4.0 head? I'm running a 4.0 head on a 4.2 block and am having trouble with the plugs fouling. Thanks. _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list
