I am by no means an expert, but if you cannot cool your car with a proper radiator and mechanical fan setup, i think you will be "chapped" with the results of an electric setup. A factory style mechanical fan moves a buttload of air!
I ran the factory setup with great results in my 73 gto, even with a number of trips to drag strip spinning up to 6k. When putting the same motor in my 68, I was starting fresh with no fan, shroud, clutch etc. Since I was starting fresh and this car is setup for regular visits to the strip, I decided to invest in a good electric fan and controller.
Same good cooling results with the Mark8 fan, but now I can have more control, save a couple horse power, cool down between runs, etc. Yes, anytime the fan is running you will be putting a good load on your battery and/or alternator.
If only running a 40amp alt, you will likely want to upgrade that to ~100amp as well.
