Small block water pumps

B'Cuda Dave,
Thanks for the info, but I agree that the 69 front covers have the timing marks cast in, I have no less than 5 covers and they are all cast in. I have actually never seen the tab type you are talking about, that may be an even older setup, not sure but I would like to see a picture.
As far as the rad hose, ask the takes your off and go to the parts store and see if they will let you look through the wall of hoses and find the "opposite" one you need then you can get the number for future reference. Thanks again for the info.
As far as keeoing the same pullies and all of that not an option, I had the motor built and I am not taking it apart to change back, so I am going with the MARCH serpentine system with new mounts and all.
