I just changed the plugs on my 83. It has the two small ones, so does my Renix block. The small plug block is the earlier one, but I don't know when AMC changed to five large plugs (and MUCH easier to deal with than the little ones!). I would think it was NLT 96 when they made other block changes, but may have been earlier. ------------- Date: Wed, 07 May 2008 02:06:34 +0000 From: Wrambler242@xxxxxxxxxxx The two small plug block has the larger tap hole the knock sensor went into. So I assume the two small plug block is earlier then the 5 larger block. -- Frank Swygert Publisher, "American Motors Cars" Magazine (AMC) For all AMC enthusiasts http://farna.home.att.net/AMC.html (free download available!) _______________________________________________ Amc-list mailing list Amc-list@xxxxxxxxxxxx http://splatter.wps.com/cgi-bin/mailman/listinfo/amc-list
