pick some gears for me
All kidding aside, you will be most comfortable, IMO with a 3.91-4.30. I am going to run a 4.30 in my 63 Dart. I am building a hot naturally aspirated slant 6 for mine. Since yours will have a pretty hot 360, you can pull a higher gear. But, keep in mind that even if you choose the same 4.30 that I am going to run, your final drive ratio will stil be only 3.139:1. What will be fun is the overdrive's first gear ratio which is 3.09:1. That would make your first gear final drive ratio 13.287:1. That would be pretty fun on the street. LOL
