Tim, please think long and hard about that and talk with your engine builder about the characteristics of your engine down around the low 2000's. I was out in my car this morning (after fixing a shifter problem from earlier this week ) and I was cruising the highway in 5th gear at 2000 RPM and doing just a hair under 70MPH. All the time I was thinking how glad I was that I went with the .64 gear in my TKO600 just for this reason. Even with the big FE and sidepipes there was only air buffeting noise. It was absolutely delightful as there was hardly any other cars on the highway. That is the only thing the .64 is good for -- pleasant highway cruising; no road racing in that gear at all. My rear end ratio is 3.54 and I have 15 inch tires. This is a subject that has been discussed ad nauseam but it's a decision you want to get right the first time (along with your rear end ratio). It'll can make a big difference to the enjoyment of your car so please do your research on it before making a final decision.
