Probably sucking in on the lower hose and limiting the flow. How old is the hose?

Lots of podsibilities.
Late timing and cruddy cooling system.
First is to flush it.
Follow these instructions.
Get a can of acid type flush, it will open on both ends usually.
Locate the drain for radiator and open it.
Now insert water hose in fill cap and adjust so water level stays full and start engine with heater full hot and idle until water comes out clear.
Shut off engine close drain and add acid then drive 30 miles
And repeat above.
Now insert neutralizer and drive 5 miles.
Repeat flush until clear and since it is summer leave as is until you are sure it is fixed.
Put Anti - freeze in when all is good or at least before winter.
Also search overheat for many other tips.

Tried everything on a 94 454. Replace the radiator.

You may also want to check and possibly replace the Catalytic Coverter. A plugged or bad converter will cause overheating by causing excessive back pressure.

I have an overheating problem with my 454. Recently a mechanic told me that the temperature sensor was located too close to the heads and that was skewing the temperature readings. I haven't had time yet to try adding a gauge elsewhere but it's food for thought I guess.
