What information can be revealed about this pump from these pictures?
It has an AF formed INTO the casting just to the left of the "18." I assume that is the foundry designation.
Heads from Windsor have a "WF" and intakes from Cleveland have the "CF" Cleveland logo.
I would guess this is a Ford instead of TRW. No Date I can tell. Based on the casting number, would it be appropriate for a Mar 66 Metuchen C-Code?
