440 going with efi?

There are a lot of home brewed systems out there and also some box systems. Right now I am following this build for megasquirt:

But also have researched some others systems such as Fitech, Holley and Edlebrock.

For my car, I am using and doing the Megasuirt Pro with a lot of insights from the Charger forum build
