Cooling help needed..! I have a 1970 gmc with a 383 stroker with very close to 500 hp. I'm running a TCI Street Fighter 700R4 trans. I have a 3 core rad that measures 28" x 18.5" with trans cooler mounted in front coming through Rad first. I have a 16" flex fan with shroud. I discovered to day that I have been running with no thermostat when I was attempting to replace it. I installed an 180 degree thermostat an im still idling at 230 degrees but highway temp is 190 degrees. I'm thinking I need electric puller fans unsure what cfm, I don't know. Any and all is appreciated, Thanks..!
