Welcome to the boards. There's a ton of info available around here in the engine swap section, so it never hurts to take a look around.
Buying a car that's been converted to something other than stock (especially from FI to carb) is probably going to be a bit of a challege, since you're never quite sure what they did to get to that point (there's a million different ways that people convert; some good, some not so much).
What kind of trans are you looking to use? What part of the country do you live (possible emissions issues)? What are your goals out of the engine?
easy answer to your question: yes. more involved: maybe.
