1977 F250 ext cab,cooling problem. have jasper rebuilt 460 with RV cam, eldabrach street manifold, msd dist.,coil,and box. Modified c6 tranny, heavy clutches,kelvar bands, large finned pan,diesel tourque converter. Have 4 row radiator, 6 blade fan. Problem is the old gal gets pretty hot aver 50mph when towing heavy (8,000-12,000lbs) in hot weather aver 75 degrees. Runs up around 210 some times over. This is with AC on or off. I do have tranny cooler in front of half the radiator adding one under bed soon(it's in my shop now). Have a 190 stat in her but rareley get down to see it close. Any ideas or sugestions to get my baby down to a more reasonable temp?, Smaller loads are not an option. New and bigger truck not really an option as I am retired from any paycheck, but do farm a little and haul stock and rock. Have been thinking about adding 2 blad electric fan to replace the enginge fan but at 50mph don't thin it will add anything. HELP Pleassse!
