Not a bad option either.
If you did a 100% stock restoration by the build sheet, I think it would be fitting to have the original numbers matching engine rebuilt. I would venture to say that this would make it the most "rare" as anyone can swap in a crate SBC or even a BBC. Not everyone can have their original, numbers matching engine.
In short, build what you have or build a BBC. Cost will be a little more for the BBC and either will cost more than a crate SBC - but you didn't cheap out on your restoration, did you? Why would you cheap out on your engine then?
