Camshaft selection and overdrive

Looking at a 224 duration (at 0.050Ē) cam and another 228 one for my 6L build. Itís a high compression pump gas build (I should be able to get by with a little more duration), and will have a 4L60e behind it. Iím open to torque converter options, depending on the cam I select, but was wondering about overdrive and bucking/drivability. Iíll probably be changing my rear gears to help raise my cruising rpms, but am debating how far to go. I do want overdrive.

What have you guys with overdrive been able to get away with for duration and have good cruise manners at 50+ mph?
