You could probably turn 39's w/o o/d and the low 1st.

i turned 38s with 3.73s with my old 4l60e lol im fine i got plenty of power

But anyways back to the original topic..

Other than pedals and a master cylinder out of our trucks. Can I use the clutch and fly wheel that would go behind our motors? Or would I have to get one for the older cdi motors?

It will have to be a vortec flywheel, they are weighted different/different bolt circle. Pressure plate should stay with the flywheel. you can put whatever clutch you want in the middle (i think they are the same). You will need to add a pilot bushing to the crankshaft. Run the slave/fork out of the sm465. I don't think any auto transfer cases cross over to a manual tho, you will need to change your transfer case input shaft or get the trans and t-case out of the same truck.

Ok thats what I was thinking. Thanks boss. And any tcase with the 6 bolt pattern and 32 spline input will work

EDIT: but the 32 spline 6 bolt tail housing was the later sm465's i think like 1975-1991. before then it was the 10 spline output for the 4wd and the 35 spline output for the 2wd

Looks like you know more about the transfer case fitment than i do. I did'n fool with that part, my manual came with a transfer case attached.

Yeah I want to run my pdrop 241 behind the 465 to get a super low, low range to make crawling way easier

also from what i've been reading the input shaft is the same size and same spline count as an nv4500 so i think this will be a relatively bolt in swap

I've seen the sm465 in some pre 92 k3500 gmt400s also. Almost bought one

 

[tanman_2006]

There are quite a few of those early gmt 400's and late square bodies.
