The '71 with the new motor always ran hot. And by hot, I mean 200-210 degrees while driving 80MPH when the temp outside was in the 40's. The last time I drove it during the day, it rose to 220 degrees and it was only 80 degrees outside. Not good.
Pulled the water pump and sure enough, it had a stamped steel impeller. Went to Auto Zone and got one with a cast impeller. Even though the stamped impeller was 4" in diameter versus the cast impeller being only 3", I drove it home tonight with a 55 degree outside temp, and the guage never went over 180, whether on the freeway or the street.
