Engine/Drivetrain / Re: SM 465 to NV4500 Question

« Last post by Captkaos on July 09, 2026, 02:48:17 pm »

The NV4500 is longer than the SM465 by like a couple inches.  AND its hydraulic, so the bell would need to change and swap to hyrdo, the tunnel cover would need to be modified for length, driveshafts, the front would need to be longer and the back shorter.  output shafts are different on the driveshaft yoke.
This is just what I vaguely remember.  I think for this to work you need a early GM specfic trans, otherwise you need adapters since most were from a Dodge.

Good Times!  I hope 

Well I was working on it with my twin brother but we discovered more problems than solutions.  I am trying to get this 1968 C10 that has been off the road since 2001 back on the road.
I got the Inline 6 running after rebuilding the carb and replacing most of the ingnition components and then discovered here was no driveshaft.
Since I wanted to actually drive it, I acquired a T5 and did a Jeep Shaft swap that we had hope to just do a pull and swap.  It really didn't work out as planned as we doing discovery on we pulled it apart. The bellhousing required a spacer that I didn't have, the retainer needed to be cut down, along with the pilot.  Then there was an issue with 20 year old wheels and no brakes.  I spent half the day trying to get fluid to all of the wheels.  Needless to say it is still up in the air, literally.

I updated your post to have the URL links so they aren't "lost" and I added one picture with the formatting. With Photobucket you need to open the image and copy the link.  All will be watermarked like the above. and if you ever loose them they will be gone like Kenny said.

sorry... I'd simply upload the photos but this site only likes jpegs with NO E.

Just download and rename them.

What you did to fix that needs to be in the Technical Pages Section.  That affects every square owner on here.

It actually is posted here: Annual Cleaning out the cowl

Blocked off cowl drain, to many leaves and the fan sucking them in and blowing into the AC box apparently into the resistor and creating ambers.
I haven't been consistent on cleaning out the cowl....

That's crazy!  Glad it turned out okay!

Don't give up.  Just upload the pics to here.  Gotta make em less than 500k  I feel your pain.  It's better than linking.  back in the day I used photobucket before they broke the entire internet.  I had hundreds of pictures linked on here.  they're all gone.  all i have left is what I've uploaded directly to this site.  I recommend doing that.  it will last in the long run.

Don't give up man!  We wanna see what you're doing!

I don't have answers, as I'm facing the same problem.  The only two ways I can see to go is a Gear Vendor overdrive, and/or an early 4l80e out of GMT400 4x4 that will work with my NP208.

Engine/Drivetrain / SM 465 to NV4500 Question

« Last post by Mike81K10 on July 07, 2026, 10:42:19 pm »

Will the NV4500 directly swap with the SM465 (have an NP205 transfer case)? Will the transmission cover in cab work with the shifter location or will it have to be relocated? Will the driveshaft have to be modified or will it work? Will the NV4500 be good for the highway? It was a while since I drove my truck and when I had it on the highway with my 383 stroker, it just needs top end assistance. Winding out and not getting the performance with the SM465. Is not good for highway? I never had a problem with my stock 350 or just didn't realize a problem in the past.

I want to keep a manual transmission! I think an automatic may be too much trouble!
