340 FLOWKOOLER HI FLOW WATER PUMP

Hi Folks

Building a mild 340 for the street. Auto transmission with OEM 3 core rad. Is there any benefit going with the Flowkooler and hi flow thermostat or am I wasting my money?

I assume that they are made to better standards, and I don't want to put crap on the engine.

BTW.......Any suggestions on temp range for the thermostat?

Thanks
Driver side or passenger side water pump inlet?
