My opinion avoid a pusher at all costs. Puller is the most efficient and the way to go,
100%.,-cord
When are you having issues, and what is your current setup ?
Car's cooling system is mostly factory stock and I'd like to keep it looking that way. I wanted to hide a pusher fan behind the grill and in front of the rad sorta of out of sight. The cooling system is all stock for a 1969 big block Dart, except I did have the factory radiator re-corded to a 3 row with 1/2 inch tubes (did not help much). Car still runs warmer then I'd like at slow speeds or at red lights. On a 80 degree day if you keep the car moving @ 45+mph its not to bad. It will run 195 to 200 degrees with a 160 degree Napa Super Stat. At lower speeds 210 to 220 degrees. I have had the car vapor lock on me a couple of times in the past and stall out, so I don't drive it much in hot weather. Also I 've put a phenolic spacer under the carb and started running Ethanol free gas, but it has not helped.
That high density core radiator should have helped.
Tell us more about the engine combo.
Stock AVS carb?
Rebuilt with what compression, cam, etc?
What fan do you have on it?
What viscous clutch?
