Magnum EFi idea? Suggestions please

I'm doing a 360 Magnum swap and 4 speed into the Duster as we speak. After seeing the difficulty and expense to make the tone ring work... I questioned my avenue for the build. I'd need to buy and modify the flywheel setup for the OEM efi. Then I'd need the wiring harness. I know some may scream that Throttle Body efi sucks and all of that... but I've been looking at a my expense and purpose. My purpose is a 300hp-325hp Magnum to drive a good bit.
Here is what I'm thinking and tell
me if I'm wrong.

4 barrel Magnum intake
Rebalance a 130 tooth Flywheel to the Magnum.
Looking at the Beer Keg intake and it's limitations, custom harness,and that... I could just EFI tech it and be done with it for less money. Thoughts ?
