Electric VS standard fan

Member here has a HEMI in his Dart and runs a http://www.smithsradiator.com/mopar/abody/index.html in his car and from what he has told me he has never had any cooling issues. If I remember right he has used everything from a cheap plastic fan with a shroud to electric ones with out any issues.......I believe he has the 2 tube 1.25" version of it....
