Having driven and worked on Regals and other G-Body cars since the late 1970's here in the desert, the factory AC has always been more than adequate and comfortable even at 100+ degree summer days, some were marginal at 110+ deg, but still tolerable?
In the later years blower motors got lazy, plastic vent and lines caused issues, and still do, and vacuum controls did not function well for the blend doors and the heat/cooling internal passages.
Many times with full AC, there was also full heat mixed in the output. Often we had to disable the hot water supply going into the dash unit for ample cooling.
The VA unit has ALL electric controls and stepping motors, no vacuum actuators and crappy vacuum lines to break or stick.
The AC evaporator is also in the passenger compartment, NOT in the engine bay subjected to all the under hood heat, especially in the summer when max cooling is really needed.
I think I mentioned in an earlier post that driving in 105 deg. summer day, the Vintage Air in my Regal, with a front mount intercooler, it was very comfortable and the blower setting was on Medium.
To further qualify this combination, the very efficient VA condenser is being used, the radiator is new and dual fans are installed, but only one fan is normally on, and certainly no antifreeze is used as we have never seen freezing temps in our summer months!
