[V8Vairs] air

Vintage Air recently switched over from vacuum operated doors run by vacuum 
switching valves to all-electric operation.  I've installed both and I'll say 
that the newer "Gen II" all-electric is the way to go.  Mounting and later 
troubleshooting VSVs is a PITA.  

Also, take a look at the construction of the evap/heater core before you make 
your decision.  Most, if not all, Vintage Air units take an existing, 
smallish, evap core and cut/weld it to create a combined 1/3 - 2/3 heater/evap core.  
Performance is OK in a moderate environment but not so OK in a tougher 
environment.  The tell tale is a big sticker that says "Never run anything but 
anti-freeze" (Unstated: if you do you will freeze and split the core)   I've 
installed other units, like "Southern Air" that had separate cores and more 
cooling/heating performance. I think Vintage "cool only" units use the whole core for 
evap.

Vintage stuff is good and they have a wide variety of options - I just don't 
like the split core for challenging environments.

<snip>I'm building a rear 4.3 V6 and I plan on using a heat-def-A/C unit from 
either Vintage Air or Hot Rod Air. They both have similar units. The Vintage 
Air unit would be their "Compac". They used to make a cable operated one but 
I think they have switched over to all electric/vacuum units. I'd like to 
use a cable operated one so I could use either the stock Corvair heater or 
A/C controls.Ed Dowds <unsnip>
