There were also carburated 2.3L Turbo enignes that were used back in '79 to '82. These were rated at 143 HP and would be a fairly easy bolt in. They ran ok, but weren't as potent as the later EFI Turbos or 5.0L EFI engines. They did give the 5.0 a run for it's money back when they were new, but the 5.0 in those years only put out about 120 HP.
If it were mine, I'd probably do a 5.0L EFI swap, simply since it's a simpler system, but you would be better off finding a complete donor car so that you have everything right there for the swap. The 5.0 EFI runs much better than a carbed version, and would make for a much better daily driver when done.
