Factory EFI A body conversion

I'm thinking about converting my 408 to factory EFI. It's got an estimated 400-450 HP. I know some folks are running the stock EFI on strokers and it doesn't really know what size the engine is.

What have you done to make the EFI work? What is needed? I will list the parts I know will be needed, please chime in with things that tripped you up or parts I might not know I need.
