What to know before adding AC

Slant Six Dan recently sold his A-body and left the site. I hate to disagree with his advice w/o him around to counter (loved to when he was here), but I don't advise a 180 F T-stat. That won't prevent over-heating any more since once a 195 F T-stat is full-open that is max coolant flow and over-heating is >210 F. A colder T-stat will cause lower mileage, more pollution, and faster engine wear. Today's oils are fine at the higher operating temperature.
