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.
