i like the question.
I never said he couldn't, in fact, the implication would be that he could. And as a matter of fact, he should be able to.
thing is though, most of us dont run it out in 5th, it is just natural to up shift to 6th.
if a person wants better MPG on the highway, then stock gearing is good, and top speed runs could be done in 5th. (perhaps shift to 6th once top speed is reached to attempt to cruise at such speed)
If a person wants the same or better top speed potential AND a harder launch off the line then modifying the final drive ratio would be necessary. for J models, i know that -1/+2 is great all-around, or -1/+3 if you want a bit more in 1st, and still want to be able to run 150-155mph
there is a gearing chart on this forum that you can use to calculate your speeds with different gearing choices.
