Alan, Regarding 36 water pumps, I have NOS ones at $75.00 each and I have a pair used that I did use for a short period of time, which were also NOS at $40. each. Can supply cores for $15.00 each. The reason I used the new for a short period of time is that I had Skip Haney build a couple. I did not notice any cooling advantage with his system. Elmer Swift twinjoan@gmail.com
