Need help on choosing electric fuel pump for carbed 5.9

Comments inside the quote
I've always been a mechanical fuel pump guy, till now I guess.
So what's changed? Would it not be cheaper and easier to convert that cam nose to drive a mechanical?or is that not possible in this case?

Putting a carbed 5.9 in my 68 Dart.
Wondering what electric fuel pump to get, where to mount it, etc.
Would love some input, and maybe some pictures.
I'm planning on using a return style regulator and running a line back to the tank.
And running all new hard line from the tank to the engine bay. I will be running my Edelbrock 1406, so single inlet carb, on top of an Edelbrock airgap manifold.
Looking at pumps on Jegs, so many choices.
