No, the six started using bridged rockers in 73, but had to go back to a shaft in late 73/74 due to a patent dispute filed by Buick. The dispute was resolved (don't know how) in time for late 74+ models to go back to bridged rockers. -------- Date: Thu, 2 Apr 2009 20:46:35 -0700 (PDT) From: Greg Taylor <amundaza@xxxxxxxxx> Hey guys, See the link below for a rocker arm shaft listed as '74 AMC I6.? Didn't '74 have bridged rocker arms, not a rocker shaft? ? http://akroncanton.craigslist.org/pts/1104506714.html -- 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
