Need a plan - component selection for restoring 68 340 that runs on 91 oct

I fully expected this would start a fun conversation. You have not disappointed. The one thing that I would love to have heard is what the original car sounded like. If that was known I would have added that criteria as well. Make it sound like it once did. But my main point is to make it street drivable and look original. Most of the suggestions have met this criteria. To answer a couple of questions. I have the stock exhaust and intake manifolds. And the stock AVS 68 manual carb. Oh and it has the original 323 rear end.
