Post Help with YJ engine / axle conversion

Hey y'all.. new Jeep sister here. Just got a '93 YJ it came to me with a 4" skyjacker lift, stock axles, and the inline 6.
Opened the I6 up for maintenance and found it needs a total rebuild.
So... sought out other options!
I've decided to drop in a sbc 350 (not what I want per se, but it's what I can afford and still finish the rest of my current plans)
After reading a lot about tire size, I figure I need to also upgrade my 30/35 axles to Fords 9" rear and Dana 44 front.
So, first question is what make/model Ford do I need to grab those from?
I found some locally out of a '79 Bronco at a fair price... will these work?
Second question... how much does a carb on the engine really affect being able to climb at steep angles?

Additional plans are to do the SOA and get bigger tires than the 33s on it.
It's a weekend warrior toy here in the Ozarks and I'm hoping to finish it up to be ready to hit Rocktoberfest in 6 weeks.

All input is appreciated!

Most of the mid to late 70's Ford 2wd pickups have a 9" rear in them. But they are getting few and far between to find. Im not sure if the 79 bronco has a 9" in it or not. An 8.8 out of an explorer will do basically the same job. 95-03 explorer 8.8 is the most popular rear to swap into a YJ.

The Dana 30 that you have for a front end will be fine for up to 35" tires. But if your heart is set on a D44, i would look for one from a wagoneer, atleast it would be coming from a vehicle with leaf springs. All of the f-150 D44's have coil spring front ends, and the radius arms will give you problems when trying to change it over.

As far as the carb question, anything steeper than a 70 degree incline, and you will have problems with a carb. atleast thats the way mine is. When all i can see is sky on the way up, if its a long pull, it will load up and sputter on me.

For the steering, if you keep the D30, everything stays the same. All you have to do is take the pump off of your motor and put it on the 350. Its a GM steering system in them anyway.
