The issue you have to deal with is getting the carburetor mounting surface high enough to clear the right side valve cover while not getting it too high, hitting the hood. The spark plug wire loom support spot welded to the valve cover had to be moved or removed on my 351. I chose to go with the '80s small block plug wire routing scheme around the front of the valve covers. The support could be re-welded a few inches forward to clear the air cleaner. This would retain a more original look.
Intake choice is also important. If you choose to go 4bbl, the '69 Mustang-Cougar intake is easiest. In my truck the Performer is too tall, tho the Performer EGR works but needs the EGR hole plugged unless you need EGR to pass emission inspection.
I use the OE exhaust manifolds so the air cleaner support works.
All this is based on using the '70-'77 air cleaner that has a longer snorkel to allow room for automatic chokes between the carb and the air cleaner housing. I haven't tried to use the early air cleaner.
