Overheating issues on a rebuilt 360

you are running an aftermarket serpentine belt and it is setup to run the pump the same direction as a v belt set up, are you using a v belt pump?

What I'm trying to get at is serp belt specific water pumps typically run counter to v belt pumps.

Not too sure what type of pump it is but the previous was running the same set up in his car and never had an overheating issue
