Seems like it would be way easier for both of us to just have you give a short description of what makes it better.
I am not trying to bust your balls, I genuinely don’t understand what could sound better,if the motor is healthy and in tune, between 1,000 rpm smack dab in the middle of the engine operating range.

Do you have a 2nd car? I would go 3.55, let the engine breathe. In CA freeway driving most areas it's 65MPH and if no traffic, you better be driving 75-85 in the fast lane or you will piss a lot of people off so now you're in the slower lanes and you can cruise along at 65-70. other option what I did when younger & speed limit was 55 on freeway, I traded my 3.23 for 4.56 and still drove all over then I started my 8 3/4 collection of other 3rd members, it takes less than 1 hr. to swap gear sets, with a few choices if you want to go a long trip swap in some freeway gears you can still do it with the 8 1/4, will just take a little longer or swap in OD trans that you have.

It’s not that deep for me. Was just trying to provide some informative discourse for the thread.

I installed an overdrive to cruise 65=2240. Much quieter, smoother, relaxing.
Before od my car was cooking 65=2870 (manual trans) and had an annoying sound at 65, notta boom, just "impatient" The body just amplified whatever the exhaust was doing.
But at 65=2240, that is gone; thank God.
My engine sounds really good at 2800, so that is my preferred shiftpoint, and I make the shift lazily. This gets me 63mph, then into od, and lets cruise.
The point is that I have a choice.
If you are limited, then just know that your 5.9 will cruise either; but always go for the lower of two choices. The 5.9M has a generous amount of bottom end torque, so 3.21s would be my choice. Allbeit; I would likely stall it at 2800or so, and run a lock-up.

Thanks for the replies. The ax-15 swap won’t happen for a while, I was sort of kidding.
Leaning towards 3.55s because at this point I wouldn’t mind an around town ripper. I’m so tired of the 2.76s out back and my exhaust has very little drone above 2500 rpm.
My only concern at this point is overheating at 70mph with 3.55s. Maybe unlikely?

Figure out the highway rpm of the two gears sets at the mph you drive. Then go to some back roads drive in 2nd at those rpms for awhile see if your ok with the 3.55.

Let the boy go !
If I take my car to work it's 40 miles each way highway. I go 80 most of the way with 323/340/4 spd.( no overheating) Yeah she's revving high. If I kill it I have an excuse to do my 408/360 build lol.
