priobe,
Something else I found that helps with cooling my FE that might help you is a Hayden adjustable fan switch. You can adjust the temp to turn on your electric fan(s) from 35 - 260 degrees. It was an easy install and I paid $25.00 at PepBoys for it. Works great when you want to heat the motor up as well when it's cold out. I am running a 180 degree thermo in my 428.
