I assume you mean computer when you say comp.
I think you have the early version of EEC, maybe 3 but probably 4, and all it runs in the car is the carb idle circuit and motor, based on the O2 sensor signal, and probably does the ac, and PS idle up function. It may control the timing but I am not sure.
I am not sure about the fuel pump, but for a carbed 5.0 you just need stuff to feed a carbed 5.0. A mechanical fuel pump if you engine has one is fine.
You will most likely need a Duraspark2 box and will need to wire it to the ignition. The existing computer can go on the shelf.
Probably the best way is to just swap the entire v8 wiring harness in the car.
Be careful, the gage cluster circuit boards are wired differently between years and should be carfully checked before you plug them in. My best starting bet is to use the carbed v8 under hood harness, the cars original under dash harness and the car gage cluster. You may need to swap the v8 tach or set the tach switch to the 8 setting if it has one.
