This is a Motorcraft 4300 Carburetor D5PE-AB that I bought many years ago as a NOS carburetor in a Ford box.  At the time I look at it and it appeared that it was installed for a short period of time on a engine as there was a little bit of soot inside.  If you look at the pictures one can see that this carb has very little use.  I never installed it on an engine so I cannot determine state of carb plus it has been sitting in storage for at least 15 years.  So I recommend a rebuild kit which can deal with the alcohol laced gasoline that is used today.  My application for Carburetor was for my 351C M code mustang cougar with automatic trans.  There may be other applications for D5PE-AB carb.
