Highway heat

Got any pictures of your set up? Are you sure the fans are pulling air? My dad has a set of pulling fans built into a shroud and aluminum radiator (Champion set up) on a 440 and it would overheat. He removed just the fans and shroud and it cooled better with no fans or shroud. He went mechanical fan and it never overheated. A lot of folks have found that the shrouds are restrictive and the fans simply can not pull enough air and it is difficult to fit an electric fan large enough to pull enough CFM to cool.
