the head is where he is supposed to be getting a temperature reading.
I suspect you have the wrong pump. Did you go to the parts store asking for a reverse rotation pump for a small block... or did you say I have an old motor with a serp conversion added?
Don't give the (typical) parts guy more info than he needs. You need a pump for a '97 5.7? That's what you ask for.
A pusher fan is not ideal. While I doubt it is your problem, if you are able to mount it on the back side and have it work properly, it'll work better. Better yet, a quality fan clutch on a mechanical fan will last you a long time and work better.
