1971 340 water pump core

I also live in MI in the Detroit area (48135). I have an older cast 8 blade from my 68' 340 Barracuda if your interested. I have a 71' Dart Swinger that has an aftermarket electronic ignition installed. I looked inside the dist. to find any make or manufacturer and could't find anything. No external module (??) the cam is covered with a black plactic sleeve. The tiny module on the plate looks like it picks up it's signal from the cam. I just want to get the car running so I can sell it. I have too many projects going and not enough time or money for all. I've been retired for a couple of years now and it's time to get rid of everything I don't need. I'd like to put the simple orange box ignition in it and keep it as close to factory parts accessible. Let me know about the water pump. The ignition has too many stray wires to mess with. I just wanted to pass that along. Thanks.
Thanks, but the cast iron pump won't work for what I'm looking to do.
