Hey Big Block guys, what diff gears are you running?

Hey Big Block guys, what diff gears are you running? I currently have a 68 swb with a 454/TH400 setup and I have 3.73 diff gears...can you see where this is headed yet? I understand 3 speed trans is the real issue here and will eventually be installing an A/T with a 4th gears, but for now this is what I have and I will make it work.. being that this is not my daily driver and I would like to cruise the highway. From what I understand a 3.08 gear option would most likely help with the higher rpms at 70+ mph, according to most rpm calculators I found online.

I'm not too sure how I will feel about "losing" some bottom end, so I'm curious what others running a 3 speed trans have "remedied" for this.
Thanks!
