(2) 12" fans versus (1) 16" fan

If your using a 26” radiator probably the best fan is a Mercedes fan from the C class. I use this on my E-body 26” radiator and it will cool it running at 25% fan speed @ idle. The most I’ve seen it go is 50%. The drawback is it needs a controller and I’m not sure about the space on an A-body.
There is an extensive write up on Moparts if anyone is interested.
