I had the same problem on my '77 1500. After verifying that the thermostat was good and the sending unit was new, I calibrated the gage by putting ceramic resistors in the wire leading to the sending unit until the gage needle sat on the hot line when the wire was grounded. After doing this, the needle would sit near the middle mark when the engine was warmed up to normal operating temperature.
