There are a number of factors involved. For example, do you have a
problem with overheating with or without AC on? Do you have to sit
and wait in traffic for long periods of time? Do you live in a hot
climate year round, or just during the peak of summer? Is it a high
Mustangs with 289s (no knowledge about 390s, etc) from the 60s were
sometimes prone to overheating, though with my 65 Mustang, back in
1970, I never had this problem. Of course, at the time, I lived in
Tacoma, WA where the weather is cool to moderate year round.
With a 302 powered Mustang in the mid 70s while living in the Mojave
Desert, with AC, I still never had a problem overheating even with
summer temps well above 110 degrees.
There are some advantages. Generally, this would be less power loss.
Since you are not going for high horsepower, and your use (as is mine)
is as a daily driver, and unless your personal situation calls for
making the switch, I personally don't think it is necessary or worth
I will be installing an aftermarket AC in my present Mustang. If I
recall correctly (not having the literature in front of me) the source
provides a 6 blade steel fan to replace the 5 blade stock fan, and
recommends the 6 blade over the present Flexifan (which may be another
option for you).
As for CFMs... I'd recommend browsing through parts catalogs such as
where you will find CFMs listed for various fans.
