Not likely. Too many variables. The IP, heads, injectors and lines must all be of the same series, application and generation or they won't fit.

I was told that the engine I bought was a bring back from the "surge", and that they are not in bad shape been thinking about a straight swap
This is a marketing point (hogwash) to sell surplus engines. It isn't likely they know where they came from. The military doesn't intentionally replace/remove good engines in working equipment.

but its a mechanical injector so I am guessing I would have to build a linkage and use a regular gas pedal and cable to achieve that.
Adapting a MFI injection pump to an EFI engine/chassis is a conversion. It's a lot more than just installing a throttle cable.

How would it affect the computer to do this?
The computer won't be happy. You'll have to do a complete conversion to MFI to make the electronics, instrumentation and tranny (if auto) work. A manual tranny is much more simple, but still requires the remainder of the system to be "converted".
