I just did a rebuild of my 352, made it a 390. Its getting a little warm with the stock radiator. I have a aluminum 4 row coming this week but I also want to put an electric fan on it. I would like to take the stock fan out and free up a little power. I feel like an aluminum radiator and an electric fan should be enough but someone recommended keeping the stock fan, aluminum radiator, and electric push fan. Do I need this or just an electric pull? Also, any recommendations of electric fan set ups? Thanks!
