Looks like you have an '82-ish CCC engine. Unfortunately that means it won't ever run right without the computer and wiring. For the sake of simplicity I'd probably look for an earlier non-feedback carb and an earlier HEI with vacuum advance. You can forgo the EGR and basically treat it like a late 70s 231 in the electrical and vacuum areas.
Also, don't expect a 231 to be much of a powerhouse. They were only ever intended to be a relatively fuel efficient method of keeping a car rolling. They could hardly get it rolling in the first place though.
Personally, it wouldn't have been my first choice for a Sammy swap but it's already there so I understand making the best of the situation.
