My cooling system sucks for Phoenix!!! What should I use?

I am just going to copy the cooling system of some of the guys around here.

It is better to be safe than sorry. I am going to go a little overboard if needed, just because of where I live.

I hope that Mark VIII fan isn't too huge. I know I will need a new water pump for it to fit though.
 
The Mark VIII is a fairly large fan. This is the only link in my favorites I could find to one. Its based on instaling one in an '88 GT.

I dont know what your engine mods are, but I had bad cooling problems with my moderately modded 289 in a '65. I used a shroud, high-efficiency 3-row brass(from NPD I think), 180 'stat and a 6-blade flex fan. Before it would boil over in 90-100* weather and after the above parts I could watch the thermostat cycle on the gage.
