my 74' has a no name aluminum bought at 4pm on a sunday cause' i needed a radiator bad and has been fine for around 5 years. it gets warm sitting in stopped traffic when it's over 110' out, but otherwise has been great. bolted right in too. the valiant has a champion that sat on the shelf for years. i bought it because i knew the no name was going to crap out soon. so much for that.
