Tom, as long as you're using points you're going to get some mechanical "slop" in the system and point bounce, especially at high rpm ("...timing jitter above 3000 rpm, plus and minus 3 degrees or so."). Switch to an electronic system and most of it will go away! While rebuild quality has slipped, I don't think that's the problem here. Even a new distributor built to OEM specs (or even a little tighter) will give similar results. Might be a little less "jitter", but still +/- a degree or two. Pertronix is the easy way to go! _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
