Moving right along!

Look like the two post lift is treating you well!

Yes it is indeed, Been using a ladder to go inside when needing to go back and forth.

My main driver, a 1978 K10 I got years ago with a 350 and th350. I swapped in a 6.2L and a 700R4. Been wanting to manual swap for years now. Push has now come to a shove since the r4 died yesterday. (Lost 3rd and 4th) I'm pretty sure i have about all the pieces needed.
Im installing an SM465 from a 1984 k10 suburban. Using a 208 T-case. Im ordering transmission gasket set and input shaft bearing and painting trans. I should have everything except rear driveshaft. I might have one of those too possibly. Ill mostly have questions about clutch linkage.
I'm not trying to make it a how to but still hoping to help answer questions some may have and having enough pictures to go with.

You should gear down, as a manual transmission requires lower gearing - it will feel boggy and gutless with gearing that is fine for an automatic, otherwise Go for it!

@JBswth Pretty sure @squaredeal91 knows what he's doing???? not his first rodeo

I'll be interested how it drives with the 3.73 gears. Mine still has the factory 3.08 gearing and I have to slip the clutch just a wee bit to get her rolling...unless I use the Low granny gear which I rarely do.
3.73's are on my "to-do" list...

My K20 with sm465, 208 with 3:73 and 31" tires is about perfect set up in my opinion. 2000 rpm at 55. I rarely need to go any faster....

Wait? Turbo?

Gonna need some pictures of this!

Turbo 6.2l diesel. Turbo kit off of a 94 and it has an injection pump from a 6.5L turned up.

All apart. When I was looking up different 32 shafts allot of them came with the pocket bearing and I guess I assumed they all did. So now I am stuck waiting till Tuesday on this bearing unless I can get one 30+ miles away. I have plenty of other things to do while I wait at least.
