I put one on my 440 back in 1991- a fresh built motor. It always ran 215 degrees: never overheated, but never ran at thermostatic temp either (180 degrees). A few years laster I swapped it out for a stock 7 blade replacement (cannot recall what prompted me to do so) - no other changes to the cooling system- and from that day forward the car ran at thermostatic temp.
