Injectors are color coded. If the caps where the electrical connector connects are orange, they are 19# (stock) The others are red or blue, but I can't remember which ones which. There are several different flow rates. Conversion kits are usually expensive from parts places.
www.stangparts.com has one for like $400 but you could buy the computer for $150 or so used on ebay, then the meter and if it were me, I'd just make the wiring for it. But anyway, to give you an idea what it would cost. You might be able to use the speed density setup by changing your injector size and using an adjustable fuel pressure regulator, but that would be even more difficult than tuning a carb which is why they made EFI in the first place.
