Amazing video

Exactly info I needed

Thank you for the video

Great video. Thanks for all the information.

I have a 94 s10 2wd and the transmission is the nv3500 and it’s bad went and bought one off marketplace and found out it’s the wrong one my shifter is up further the one I bought is 2 far back as well as some other small issues that won’t work on my truck

You didn't have an NV4500

Is the zf6 for sale?

Are what I need to do that . Thank for any information

Hey GH Dezign, This is really great info! Thank you for going to the effort and sharing your knowledge here. Just a couple of things; There is no way the SM465 (CH-465) has the same shifter to bell-housing (face / back of engine) measurement as a NV4500 or ZF6 S6-650. I have a ZF6 S6-650 sitting in my garage waiting to go into my 89 1ton square-body dually. It is 15.75” as you say. I do not have a SM465 here to measure up; it must be a lot less through looking at the factory cutout impression in the truck’s transmission tunnel. I don’t have a NV4500 here either. If it is the same measurement as the ZF6 S6-650, that’s good to know and a help for this swap. 2nd thing and you may be just the man to ask this. I am mounting the ZF6 S6-650 to the original TBI 454 L19 (IV Mark 4, 2 PC seal). What flywheel pilot gearing and clutch Assy do I need? What I do know; the trans input shaft is 10 spline Ø1.375”and I will have to use a concentric slave cylinder. That’s about it. Thanks for your help! Cheers, Grant.

Very useful info. Im planning doing a turbo 5.3 pony truck and want it to be manual. Im sure i will need to watch this again as i move forward

Very very good video..and very helpful for me..made me realize how many different ones there are to choose from.. I've been using the nv3500 behide 350's in 40 & 50's rat rod cars and everything has been super easy to make it work perfectly.. the shifter location lands in a good spot..and I use S10/Silverado fluid reservoirs ..and truck pilot bearing

Really appreciate the video I was debating on a nv3500 I didn't realize the shifter was that close to the bell housing

can't find the 3500 length online and remembered you did a comparison, thank you for this info

My favorite one is the SM465

Thank you for this!

Thanks for the info I have a c20 with a 4 speed and I want a 5 speed in there and this helps out a lot !!

The k1500 4x4 trucks had nv3500's in them with an external slave. Some call them a getrag, but in all truth and actuality, they're still a nv3500. 99 and 2000 1st gen nbs trucks used an nv3500 with the 4.8-5.3 trucks as well. Very rare to find though.

A lot of great info here, thanks! I am about to swap an LS style T-56 behind a one piece RMS Chevy 350 and have heard mixed reviews on what pilot bushing to use. I purchased spacers that go between the bell housing and front plate of the transmission to fix the long input stick out, just wondering if you have any experience with this. Also, do you know for sure if an LS T-56 clutch will bolt to the old school SBC flywheel? Thanks!
