Thinking about turbo on my/6 again...

As title says
85 d150 long bed, currently 727 which may stay
Other trans choices on hand are an 833 od or an a500.... Yes I have the 60s era /6 to sb trans adapter plate for that possibility
Currently 3.21 gear, not looking at changing much from there whether I do the turbo or not.
Daily driver/ may pull a small camper or utility trailer with a few mowers on it occasionally
Daily commute 70 miles round trip, mostly 65mph, about 4 stop signs between here and there, mostly cornfield lines, rural state 2 lane road.

I hope by "daily driver" this is one you want to drive daily, not one you have to drive daily. This will be enough of a fabrication and tuning challenge that you should plan on significant down time before it's completed
Not looking for more than 6-8 psi at most. Mostly looking for wow factor at an occasional cruise night. At the beginning want to run my super 6 with nos 318 carb. Want to stay carbureted.
Thinking draw thru.

Personally I suspect that a draw through carb may be a little easier to tune, but it's still a fair amount of work. Also, draw through pretty much rules out intercooling.
Would a turbo from a lebaron turbo coupe be enough? Not looking to race. "It's a truck"
My first turbo setup used a K car turbo, and I would not recommend it. These can easily exceed your target boost well below your torque converter stall speed, and run out of breath below 3000 rpm.
And I want to retain factory ac
Doable but an extra challenge.
