Changing LS back to Fuel Injected from Carbureted

Looking at a truck to buy and it is an LS3 swap with 700r4. It is carbureted. Anyone ever changed back to Fuel injected? What do I need as far as parts go? I have tools and have done a couple LS swaps just not at all familiar with carbureted conversions.

im helping convert a 69 camaro from a carb'd lq4 to an LSA blower;

Wiring Harness, fuel system, intake manifold and o2 sensors, with the 700R4 you will have to figure out a way to make the tv cable work.

You might be better off going with aftermarket FI like Holley. It would bolt on the existing intake and give provisions for the TV cable on the trans.
