I may have found what I am looking for. I clockwise spinning LS1 water pump. I know that this is not needed however it was the old school look and simplicity that I was seeking. This pump is simple and purpose, no heater outlets, no accessory mounts and the option to machine up a nice serpentine pulley. However no provission for a thermostat in the intlet, so I can only see that one may be able to be located in the outlet neck but I dont know that this will work. So in all whilst I found what I was looking for, it may not suit my requirement unless there is an option for the thermostat (I have contacted them seeking some details).
Short of this, this I like your set up boxhead, it deletes the high mount tensioner that I have on the water inlet and outlet side, neater and purposeful.
