Autolite or FoMoCo
« on: May 01, 2017, 12:24:21 AM »
Is there a simple answer to when distributor castings went through the change of being marked Autolite to being marked FoMoCo or vise versa ? I haven't looked much as to the differences between the two (markings) but as combing through this part and many others this kind of ID and time frame comes into play.

No simple answer I am aware of .The transition on the distributors seemed to happened in the early part of the 67 model year relatively speaking. I have seen some bouncing back and forth of trademark during the early time period at least on some of the ones i have studied.  It also seemed to vary on the distributor application also. I have only studied the 289 hipo and 427 duel point . Those seem to have different change over times. Others will have to comment on different application change over times.

Thanks Bob, so the progression would be FoMoCo, Autolite, then Motorcraft, Motorcraft being service replacement parts ?

By 1972, I think that most if not all of the distributors were marked MOTORCRAFT.

Think its much easier to compare assembly dates on the dist in question (as long as it hasn't been restamped)  to get your answer and to find a usable one for your application

Jeff you are right, in this instance a view of the big picture was the point.

You got it. As I had said before there seemed to be a little flip flopping (according to dates on dist)at the transition point. Not a hard and fast line which probably had to do with supplies. I can't give any insight on the Motorcraft  transition. I never paid much attention to the Autolite /Motorcraft transition because for my purposes i was not concerned about anything marked Motorcraft.

The distributors that made me ask are two I just picked up one is C5AF-E with a date of 6M6, and a C6AF-AZ with a date of 6M19, the first being a FoMoCo and the second a autolite. The first being a Shelby application and the second a non production sohc part.
