440 cooling

I have been through this, 440 .060 over big roller 11to1 compression tried the brass 3 row, no good. Tried aluminum 1" tube 2 row with electric fan, no go. Went to a 2 row 1 1/4" tube aluminum two electric fans with shroud total CFM 4600 with duel fan control, moved the trans cooler under the fender it has its own fan and thermostat. It will now maintain 180* idling with the second fan cycling on and off. Haven't driven it yet but am sure it will be fine running down the road, oh I also added a front air dam.
