I'm Awesome
So much for trying them again. Even with a 34x19 dual core radiator and dual 3,000 cfm 16" fans my 383 tried to lose its cool and that was not even pulling my travel trailer. I picked up a 31x17 dual core radiator to allow me to refit the mostly intact factory junkyard fan shroud I scored at the treasure yard yesterday. Ordered a severe duty fan clutch and found a Motorcraft YA249 11 blade fan thats mounting and bolt circle dimensions match the Vortec clutch. If you live in a hot area where you need ac 24x7, make decent power, have a heavy vehicle and tow, best to just leave the electric fans to the drag racers. With a decent mechanical fan and shroud my small block won't run over 190°F in the dead of summer. With the electrics screaming it got to 220°F yesterday before I backed off and let it cool down.
