NV4500 Installation Questions

Hello, all. I pulled my SM465 and 205 this past weekend and plan to put in a NV4500 with the advanced adapters t-case and bell housing adapters. My questions for those that have done this:

Can I leave the engine where it is or do I have to move it up?( I’d rather not move it)
Will the original transmission crossmember work and does it have to be moved back?

Is it going to be a problem fitting the t-case shifter? I have bucket seats with a console.

This is on a 72 Blazer with a GM 383HT crate motor.

Thanks

Re: NV4500 Installation Questions

Sub’d. Hopefully someone will give you input. I want to do this same mod.

There are a couple of threads related but from what I found the threads focused on trucks or second generation Blazers.

Re: NV4500 Installation Questions

I've been gathering parts for a long time so I have ideas, but haven't done the swap...
I'm not sure how you plan to adapt the old style TC to the (I assume) round pattern 32 spline 4x4 NV4500 output. I snagged a round pattern NP205 and got a TC shifter bracket with it from AA since the old one mounts to the original adapter.
I'd measure the length (front to back) of the old and new BH, adapters, transmissions and so on, then put the numbers in a spreadsheet (or just do the math) to see where things line up.
Moving a crossmember is pretty easy so to me that's not a worry. If the NP205 has a brace on the side that's a consideration.
I doubt that the swap in a truck is really any different is a same body blazer vs truck and not significantly different in a 67(9)-72 vs square. At least later squarebodies used a hydraulic clutch so there's a thought.
I parted a 91 suburban for the TC and a lot of parts including lots of AA parts. The BH is a mechanical style TH bearing with a part number that comes back as for a V6. I drove the truck so I know it works...
