I have a 72 400 in my 69 firebird, she runs good and when just parked up running or driving around she is 180 to 190 degrees. If I am sitting in traffic it will climb to around 200 degrees and the idle gets funky, I figure this is all heat related and was wondering any suggestions. I plan on adding an extra electric fan that I can flip on when I am sitting in traffic but was wondering what others have done. Thanks for any info and look forward to hearing what others have done.
