Agree with your opinion about the cooling system design. Even now after having 
the radiator, thermostat, and fans replaced, I still see the temperature 
climb rather quickly to the 100 degree mark in stop and go traffic. It hasn't 
climbed above that mark, but I hate sneaking looks at the temperature gauge 
and wondering if it's going to climb into the overheating range.

I remember a few listers stating that they had installed additional pusher 
fans to help with air flow, but when I took a look at some of the units at 
the local pep boys I'm wondering how they shoe horned them in. Any one have 
any experience with that installation, or remember what brand units were 
used?

91 V8 - which I just found out is blowing warm air from the AC. Another item 
to address.
