" From: "John Elle" <johnelle@xxxxxxxxx> " " " " The 232 and 258 AMC I-6 are internally balanced, flex " plates can be swapped back and forth like spark plugs. " I do not know how many AMC i-6's are internally balanced " but I am under the impression they all are. the more i think about it, the more i'm convinced that all inline sixes are internally balanced by their very nature. i haven't yet heard of one that isn't. ________________________________________________________________________ Andrew Hay the genius nature internet rambler is to see what all have seen adh@xxxxxxxxxxxxxxxxx and think what none thought _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
