Cameo Ivory 1967
My flex fan got trashed and it was discontinued by Flexalight. During my research, I screwed up and ordered a 17" fan instead of an 18". It made no difference in cooling at all... still stays firm at 160 degrees. Im sure it save a few HP by shrinking the fan diameter... would be cool to test these things.maybe try a fan without the clutch. had a firebird that would heat up. i changed to a straight fan never had the problem again. but a new clutch on the fan should have fixed it. your stock fan should keep it cool.take a piece of paper put it in front of the radiator see if it pulls the paper toward the radiator. hope you get it fixed.
