New guy with 400 big block
I have a 1995 jeep wrangler that I am putting a 1976 400 big block in. I need to know what manual transmission I can use and what transfer case I can use. Can you guys help me with this?
Thank you

Couple ways to go.....
NP435 was the stick of choice when it came to the trucks. There is an "A" and "L" version. The "A" version has a 4.56 1st gear where as the "L" has a 6.68 1st gear. Great trans if this is just for off road.
Another great 4 speed is the T18 with 6.32 1st gear. It can handle a decent amount of power and is short. Usually you can make it up to a D20 or D300 with ease.
If on road, I'd suggest looking for an NV4500. Stout, 5 gears, downside is the length. If you are linking the suspension then you can get it to fit.
With all of the manuals, you'll have to either find a BB bellhousing or have an adapter fabricated or located.
For a t-case there are two big aftermarket ones, Stak & Atlas. Both can be built to your specs and are strong, but both come with a price. Stockers would be a D300, D20, NP203 and the NP205.
A lot of what you decide will come from what the purpose of the jeep is and how built up will the motor be.

Make sure the crank is drilled for a pilot shaft bearing for the trans. input shaft.

Not sure about being internally balanced but if the crank is not drilled for a pilot bearing then you'll have to go with an auto or swap cranks.
If you do not have a drilled crank, you can build an auto with a full manual valve body, reverse shift and then install a t-case with a very nice low range.
What is the main purpose going to be? Rock, mud, woods, racing?
