How would I go about a proper efi conversion?

For context I finally got my dream car (1966 Oldsmobile Toronado ) and I’m in the process of buying and stocking up parts to replace and things to buy just to make life easier for me with an older car. One of the big ones is that I would like to change it from its carburetor to an electronic fuel injection. I’m a little swamped in what all I actually need so just looking for advice like if I need to get a new electronic fuel pump, an mds or other ignition system or anything else that I actually need for it. Thank you in advance and sorry about the rambling.
