Still running hot after new water pump and thermostat

Here's my update. I have installed the new Gates water pump, new 185 degree thermostat, new thermal fan clutch, all new anti-freeze, changed oil to 10-40 Mobile 1 full synthetic, new filter, flushed radiator with a regular hose pipe, checked radiator hoses, and other misc things. I started it up today and let it idle exactly 30 minutes. When I cut it off the temp gauge was between the A and L on the NORMAL mark. It's 88 degrees outside today and it wouldn't usually be over the NO mark on the NORMAL mark. I'm starting to believe it may be electrical. I replaced my temperature sending unit before the water pump failed, about a year ago. The one they gave me was larger in diameter where the brass/copper part went into the intake but the threads were the same. Then where the wire plugs on was larger too, I had to spread my temperature connectors wire open more so it would slide over the threads of the new sending unit. Other than that I'm at a complete lose now what could be wrong.

Mine was seriously overheating after the thermostat change, i drove the front wheels onto the lift, which raised it about like a drive on ramp. it burped some. I squeezed the crap out of the upper hose and it really burped. After that it ran cool as before.

Well I tried the BURP technique and I may have had a little air but the temp gauge goes to the same place. Are they different sending unit ohms/voltages on a 302 sending unit? Like I mentioned above, this sending unit is more robust than my original.
Thanks

Make sure your fan is pulling air towards the engine not away! lol, may sound goofy but my buddy traded for a truck and they installed a clockwise style fan instead of counter or viseversa and was over heatin like a ****
