I'm pretty sure that decodes as:
D=Day shift or Line assembled on
038=day of year-February 7th
4=Year-1974 or 1984
1=first shift
R=plant code-in this case,could stand for either Muncie or Saginaw

have to look at this pump closer..supposed to have come off an original 68 BB car..

If it came from a 1968,it will have the pop off Valve on top too.
Can you see the pump casting number as well?
