/6 running hot - what are your temperatures?

Hey guys and gals. My '74 duster (which has been sitting many years) has reached the point where I cant drive more than 10 minutes without it getting too hot. As in, puking as soon as I shut it off. I've replaced the 22" radiator with a 24" (from A/C car), with fan shroud and also a 17" 6 blade fan. This thing should COOL. I have no thermostat and a 16# cap

So taking some temps yesterday with the gauge just shy of 250, I get:

1. Thermostat housing - 240
2. next to temp sensor - 235
3. upper radiator hose - never exceeded 220
4. lower radiator hose - never exceeded 190

I couldn't check the radiator temps because of my condenser, but it had good air flow.

What difference do you usually see between the radiator hoses?

Thanks.
