Here is an Ebay auction for a rebuilt C5OE 8505 B Hipo water pump by Ebay member "acond classic american auto_parts" with a Buy-It-Now of $429.00:

This is a very rare correct original Ford water pump which is correct for late 1965 and early 1966 Mustang and Shelby 289 engines, the only difference being that a HIPO will likely use a different impeller. I had it professionally rebuilt for a high end restoration Mustang and never used it. This casting number is very hard to find because of the limited production time of use. Would be a good candidate for a late 65 or early 66 Mustang, HIPO or Shelby.
