Radiator tips for 67 Dart with 440
I'm chasing the same problem on my 67. I have the same scoop as you. The problem as I see it is that the air pressure on the back side of the radiator to too close to the air pressure on the front side. I am adding a front spoiler (www.spoilersbyrandy.com) to try and alleviate the difference. Sealing the scoop to the carb would help also, but I'm going to wait to see what the spoiler does.
