Doing a search will answer just about all your questions
To figure out if you have EFI engine harness or not, you simply need to see if there is connectors for the EGR, ECT, TPS and so forth. Very basic. You can also see if the stock ECU is still in the vehicle.
Even if you have EFI, you can still remove the engine bay harness and the computer and just do some wiring for the ignition system using the stock part of the EFI ignition harness.
Theres lots of options out there for your igntion system from using the older Ford Duraspark, using an MSD application, an old vacuum advance distributer or even some people use Chevy's HEI.
Some people also use there stock EFI pump and fuel lines by using a good quality adjustable FPR.
You will have to see if anyone who has done the swap here (many have ) and see what methods they used for the swap.
Research, research, research

Then how do you expect to do the swap? If you looking to do this own your own the first time, more power to you. But i would highly recomend doing a search and gathering as much info as you can
