Let's talk about fixed-blade fans
Thanks for the advice SS.
It's a 2-row radiator. Seems like it should be plenty, as this car does not have air conditioning.
I think I actually have an original Mopar clutch fan. I planned to use it on the '73 Sport, but it's not even close to being back together yet.
I was looking through the '75 FSM and thought I would post how Ma Mopar equipped various A-bodies in the day:
225-
19 or 22" radiator. No shroud unless AC and or maximum cooling pkg.
All fans fixed. Fan size 17-1/2 4 blade, AC and max cooling used 18" 7-blade
318-
19 or 26" radiator. All models used shroud.
All fans fixed except California AC and Max cooling which used fluid fan.
Manual/Auto non AC used 18-1/2" 4-blade fixed, CA used 18-1/2 5 blade flex.
AC/max cooling models used 20" 5-blade flex(this is what I have and wouldn't fit) California cars used the 20" fluid fan.
360-
All used shroud. All used 20" 7-blade fluid fan.
195 degree thermostat all models.
What I am talking about in the original post are flex fans, not fixed, my mistake.
