My 72 350/350 with factory air never gets above 180-185. I live in south Florida and have NEVER had an overheating problem with a shroud, 7 blade and a clutch. If you go electric, you may need to upgrade your electrical system (charging) as they suck a lot more current than you alternator was designed for. A friend had a 454 71 Vette that ALWAYS overheated with electric fans and he ALWAYS had a weak battery. And that was after a total pro restoration. And for me, I don't like to listen to the roar of the electric fans at idle or when first shut down.
