Narrative:

ZMA, dolphin 355 degree radial. Both captain and I set up and briefed the 355 degree radial of the fll 8 thndr transition instead of the correct 335 degree radial. Intercepted and while flying this radial told to fly heading 330 degrees and within 30 seconds cleared direct lakeland on course. No conflicts reported by ATC. More attention to numbers would have helped. 335 looked a lot like 355 to both of us.
