Open to Closed cooling system problem?

[90eliminator]

Well the system has been converted I think, the old radiator for a new one from a 97, new heater lines to the heater core, bypassing the control valve, but It now overheats. Do I need to change the coolant neck to a newer neck, or should I do simple things first like change the thermostat and then the water pump which is only a year old or so. The system slowly heats up, and then just continues till it overheats, never draws fluid from the overflow tank, and there is no heat when I turn the heat on. So my assumption is that coolant is not getting into the block at all? sound correct. Thanks for any advice!!

did you burp the system? where did you mount the new overflow tank?

Are you running an open radiator and the closed system tank, or is it an open system tank?

open radiator and open tank, moved the tank to the area next to the rad, where the airbox used to be, put a new air filter on it... so there was space for it.
