No electric, but I did put on a fan shroud from a '59 - '60 and it's done WONDERs for my cooling. I don't think I'll even bother with electric at this point.
I sat this summer with it at BTT50's waiting to get it when it was 90F outside and another rod's exhaust in my nose with NO problems. Used to start bubbling over when sitting at a stop light sometimes but now she's A O K.
