Love e-fans. Def the way to go. Frees up some space in the front as well and is better for your water pump! May get a pony or two more as well. Flex-a-lite fans are pretty good. Try to get the one with a built in shroud so you get maximum cooling. Some call em Blacktragic fans. I had good luck with mine.
I would definately go the electric fan route. I am planning on doing that on my 69 Coupe also. I do believe you will also gain a few horses also by elimenating the belt driven fan. Let me know which one you use & if you like it. BTW my avitar pic is my 69 Coupe loaded on a friends trailer for the trip back to NJ back in August.
