Electric VS standard fan

On my 89 ramcharger (modified 360 using the stock 318 radiator) I pulled an electric fan setup from a late 90's Dodge Intrepid. Don;t know the CFM rating, but it was a dual fan setup with the shroud and fans as one whole assembly. cost about $40 w/ the wiring pigtails. I then bought a new themostatic control unit from Flexalite. it gradually increases fan speed from 60% to 100% depending on coolant temp. No instant large draw for the electrical system that way. Bottom line, it worked like a charm. The shroud had the mounting holes and all I had to do was tack weld 4 long bolts to the sides of the radiator as mounting points. easy as pie.

BTW - the controller unit is adjustable - so you can adjust at what temp you want it to kick in.

I'm pretty sure I'll do something similar w/ all my Muscle cars - the catch is that the electrical system needs to be able to power it. Not sure if the stock output alternators in the older cars can handle that draw.
