First off I have a 408 Stroker and yellow rose does not. I run electric fans yellow rose does not. I have tried electric fans with shroud on a stock radiator yellow rose has not. I still have it in my shed yellow rose does not. I have and aftermarket radiator and yellow rose does not and I use to electric fans pressed up against it successfully and yellow rose does not. As soon as I ditched that stock radiator and got a nice cheap Summit radiator and put the fans right on there and no shroud all of my overheating problems have went away. That's my experience....
