Thank you for the photos of the service manual.
I've been considering Conanski's comment about getting a 5.8 vs another 5.0, and I think it makes good sense. Does anyone know what type of compatibility problems I'd run into in terms of being able to use my original transmission (5sp manual that was recently rebuilt), exhaust manifolds and Y pipe, EFI system (assuming I don't harvest the EFI from a donor vehicle), PCM and wiring, etc?

If it has a 5.0 just run the 5.0
Great you have a 5 speed
I would just do some performance mods for your 5.0 and watch for a mustang motor you can get cheap someday
Took me 40 years to find a boss motor for my 69 mustang

That is correct
The cam profiles are different
I think he would be okay with a 5 speed
Something to think about like you said

To accomplish this swap as effortlessly as possible a complete 5.8 EFI motor(from throttlybody to oilpan) is needed because very few engine parts from the 5.0 will tranfer to the 5.8, the accessory brackets are one of the few that will. Any 5.8 can be used but the early version(88-92) will be the most seamless, there were a couple sensor and wiring differences in the later years that can be dealt with but make the job slightly less plug and play.

Both motors also use the same engine wiring so no changes needed there, and while a stock 5.8 will run on a 5.0 computer it is better to have the matching 5.8 PCM.
