Yes it should bolt up. Pay attention to the intake gaskets, use the newer mustang ones... You want to avoid coolant and vacuum leaks.
I do not want to speak for anyone else, but this question has been posed before... I do not want to minimum your needs, but there is just not one manual that is available out there to make the conversion.
And there is alot of info out there from others that have been there and done that. You need to do your research, buy a manual or two, and understand how everything (EFI) works. How to by-pass unwanted smog equipment, if that is what you want... Unless you use all brand new parts, there always seems to be some type of troubleshooting that needs to be done.
On one of Ryans websites, he has the articles that were in Bronco Driver on doing a EFI conversion, maybe that is the direction you were being pointed....
