Water Pump (FOMOCO) stamp

[Stone1965]

Can anyone tell me is this is an original water pump cast in 1965 or if the is factory replacement cast at a different time? Is the FOMOCO stamp correct for a 1965 June thru August casting?

Is correct for 1965 cars with 289

8505B - suffix B would be a second revision from the original Fairlane application

Fomoco was used about1960 to late 65 then rotunda and then autolite then back to motorcraft again by early 70s

Yes to numbers matching for 65 mustang , in my humble opinion.

Good info. Thank you. However, I thought the FOMOCO had an oval around it in the 60's and changed to the style on the pump in the 70's. Not sure the name of the style on the pump. Can you give me any more info on this? This is all new to me and I am just try to sort it all out.

I don't know at that point, Maybe some else can weigh in.

No worries. Thanks for the other info though.

Looks correct for late 1965 Mustangs.
