I will take a crack at this one. :-) I would think a big block car should have a 26" radiator and not a 22" which would be correct for SB or /6. This would be the first thing I would upgrade to address your cooling issue. I have heard mostly negative things about using pusher fans from "they do little to nothing" to "they hurt cooling". I have heard some say they can actually obstruct airflow through the radiator when you are cruising because they sit in front of it. At idle, it might help some, but I would not pursue this course of action. In addition, you will most likely have to upgrade the charging system to handle the extra current draw since you will want to run that fan @ idle where your alternator output is at its lowest. Also, make sure your fan shoud is well-fitted (better have one). If I were you, I'd see about going to the larger radiator first. I think a 22" radiator with a BB is a little tiny.

I used this one on my 68 charger because I had the exact overheating problem at idle plus my A/C would stop blowing cold at idle. Installing this fan solved both issues. http://www.the-fan-man.com/shop/size-pus...316f4ddd4b70a22But you may have to upgrade your alt. I have it wired to come on automatically with the a/c or if the temp goes over 175.

Fan shroud? That can make all the difference. I cooled my 440 with a 22" 3 row, shroud, and solid fan.
Yep i have a nice factory shroud and the fan is about 2 inches away from it.

So far I have had the stock 22 inch recently radiator flushed out and cleaned. I am running straight distilled water and some soluble oil as an additive. I also installed a higher output water pump and am running a stock clutch fan.
...
Do you have a stock fan shroud on it?
Could also have to do with the carb tune and timing curve/events of the motor.

What is the amound the fan is sunk into the fan shroud opening? Like 50/50 in and out. Or something else?
What is the minimum gap between the fan tip and shroud edge? Probably not 100% perfect consistant gap all the way around and that's fine.

I believe you want the fan to be ~2/3 of the way into the shroud. Can someone clarify
50/50. Half in and half out.

Straight water is not the best coolant !
Straight water will transfer heat better than anti-freeze or the water/anti-freeze mix.
However, your boiling point is not going to be near as high as with coolant added so always a danger of boiling the coolant which could blow a hose!

So is that the definate answer for fan placement as i have always wondered what was the best. I thought as close to the radiator as possible, but it seems not.
