So...
Stupid me is going to throw this out there...

Peak torque is at 5300...
It makes plenty good torque for a 3.75" stroke...
If it falls to 6200 at the gear change I'm going to say you're leaving some power on the table...
I would think if you send dyno sheets to someone like Coan, they could dial you in...
May find you can tighten it a bit?

I think maybe play with the shift point...
As in higher... 7200? maybe more...
See where it slows down...

More gear would help, as would a 3 speed...
If it crosses 72+ it really doesn't matter if the motor doesn't self disassemble...
(don't know the parts or build)
I see things I might try if it were mine...

Depends on your budget really, converters/transmissions aren't cheap these days...

Any way just a few thoughts from a dumb ol' Texas boy...
Maybe some of this helps...
Maybe it don't...
As they say... "Your mileage may vary"

Sorry... Thinking Chrysler...

So...Yeah, Think I'd experiment with shift point, doesn't cost anything, just time...
Still think more gear...
Converter...
There's stuff to try before springing for a trans...
Haven't tinkered with LS stuff...

There?s no question, more gear, higher shift, maybe a converter but not before real data via a data logged but not a 3 speed trans.

I am still waiting for you to post something other than a vague generalized statement.

I don't know you, but from reading some of your other posts here, this does seem to be the way you roll.

and I'm still waiting for you to post photos and time slips of your car, rather than your theory and formulas.

In almost ever thread I have seen you post in, you have had a different opinion than everyone else posting. I will just let the readers of this thread decide which of us is shoveling s h i t.
