So... a HO style EFI system is both MPFI and SEFI...

Ok you two jokers...since I held my tounge on that very issue
Carb is easier...if you don't know what parts you need for EFI. If you can find a complete EFI setup to purchase...it should be a straight forward swap...except maybe the wiring. The easiest I would assume would be a EFI wiring harness from an 86 GT(along with an 86 GT Fuel tank).
But if you put past the simplicity...or complexity of a system...you can ask yourself will you DO better with carb or EFI...which in turn will bring opinions from people saying carb is better, or EFI is better...in which some cases, both sides can be proven right or wrong.
Me personally...I'd go EFI.
No matter where you go, there you are
MPFI = SEFI = TPI...etc. etc.
Yeah they all do/are the same thing. But each is a proprietary name of sorts.
I don't call the Mustang's induction MPFI just like I don't call it's limited slip differential Posi-Trac or Sure-Grip.

Also, do not be so quick to judge someone's comments as being derogatory. It is often difficult to interpret someone's intentions having only text and no body language or tone of voice to guide you.

well now that everybody has chimed in with the school teacher antics , nobody answered the the question, everybody was quick to point out how they had there ownidea of what type of fuel inj is for each make of car, the question remains...has anybody done the conversion and is it worth it ?
Hmmm... Well... I've haven't worked with a CFI car... and I was hoping that someone that had done that swap before would chime in... I'm currently in the process of swapping from carb to MPFI... but I'm not using the Ford ECU or harness...
Anyways... If the CFI fuel system is up to running the MPFI system... then it would seem that what your really talking about is a Harness/ECU/Intake swap... which should be like a 85 carb to mpfi swap without the fuel system hassles... You probably want a 86 Harness...
Now the CFI to Carb swap is a common swap and there are a few websites that detail what it takes... Heres 2 of them that come to mind...

Sorry... I can't be more helpful... but I have a definate lack of experience with the subject and I don't want to lead you in the wrong direction...
Sidenote... One of these days I'd like to mount 2 CFI Throttle Bodies on a Dual Quad intake... I think it would make a cool setup for a SB engine...
