efi or carb

i have 11 days before retiring and have 4 magnum swaps that i want to work on. 2 are trucks and 2 a bodies. i will probably be keeping 1 truck and 1 car (car for grand daughter if she helps like she states haha). i have complete engines and several o/d trans. don't really want to redo tunnel in cars at this time. but back to orig post. what are the pitfalls of either? all comments appreciated. intake cost for carb swap, i searched "search tempest" 750 miles from home and only found 1 carb intake for magnum. i have all wiring for all engines and they are complete. if you were to purchase a magnum swap vehicle, what would you want,carb or fi? there is a thread on here that the guy makes a lot of sense when he says trying to buy a part on the road for a tbi/fi unit might be tough to find. thanks for looking and commenting.
