" From: "Jim Blair" <carnuck@xxxxxxxxxxx> " " " A: The biggest issue is when did they stop using the Buick nailhead TH400 " with adapter and switch to a Jag only bellhousing? Perhaps the V12s got the " TH400 earlier than in Canada as I recall mine being a '74 and it had the " ring. i can't imagine a small outfit like jag doing that even if they were english. it just makes far more sense to use the same tranny across the board with the same engine, and in the v12 xjs it was the bw m12 until '78 or so, then the th400. did they ever switch to a jag-pattern th400? afaik the 4L80e is, but maybe the th400 never was. ________________________________________________________________________ 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
