Overheating issues on a rebuilt 360

So I’ve recently rebuilt my 360 haven’t really gotten to break it in yet due to the overheating issues I’m currently facing I even took the thermostat out so the I wouldn’t have to worry about that and still I’m overheating not really sure why thought it could be cause the radiator wasn’t bled but that wasn’t the issue the water pump is basically brand new and so is the coolant in the radiator I don’t have any leaks any help on how I could diagnose this or what I should change would very much appreciated I’ll post pictures later
You haven't mentioned the fan? Is it shrouded? Generally when breaking in an engine there is a heat Spike but it drops back down generally pretty quickly. I've kept a water hose handy and just ran it over the top of the radiator cool it down during the heat Spike and generally the temperature comes back down. Also verifying your temperature gauge is working properly with an external heat gun. It could be a bad radiator cap all kinds of stuff...
the picture is worth a thousand words if you give a shot of your setup and your fan and things like that it may help..
