I found a GM NV4500 out of a late '94 truck that is 2WD. This pic shows the bolt pattern ~~~>

This pic shows it with a Ford FE bellhousing and an Advance Adapter unit between them; it was modified to work, but I wont be able to use it with the 4BT.

I have asked a bunch of questions about the pre-CR bolt pattern before and now cant find the info that told me which Dodge input would make the early GM NV4500 work with the 4BT. IIRC it had something to do with measurements; I think 1 1/8" vs 1 1/4" and such. I also cant find my notes as to which bellhousing will work to bolt these two together. To top it off those notes also had the info about what donors I can find this stuff in. :rasta: I'd appreciate it if somebody could help re-skool the NOOB here. THANKS! :beer:

What engines use the "Ford FE" pattern. Not everybody on here is familiar with what that designation.
ALSO, read my thread on "comparing the differences" found in the transmission sticky. Note the post on using an AA adapter from the NV4500 to Ford pattern. If the FE is the smallblock Ford pattern, I6 through 351engine pattern, that should in theory directly bolt onto the Cummins/Ford/Borg Warner step van engine adapter.

you would need to get a sbc bellhousing and the chevy adapter parts for the 4bt
Bobs, the FE is a designation used for 360, 390. 427, and 428 "big blocks." There are a few other engines in that family, but I'm not familiar with them

I have one of the early GM nv4500. I used the stock chevy bell and the chevy adapter that came on my 4bt out of the bread truck. every thing pretty muched bolted together. i did have to make a custom slave due to some fit issues with the starter on the adapter. I used a stock Jeep slave which I think was an early GM product and it works very well for me.

Do you know what donors may have that same bell and adapter if I dont find one attached to the 4BT in a bread truck? What Jeep slave did you use and did you do a tech article on it?

Just a couple more 352, the mighty 406, 410, and there were some oddball truck motors like the 391.

What does it take to bolt the FE to an nv4500, I have a 1975 f250 with np435, divorced transfer case, 4.10's. An OD transmission would be nice.

the bellhousing and adpater I will have when I get this NV4500. I'll contact you when I get it.

It makes sense that it would, but where can I find them :confused:

If I use this 6.5 bellhousing how does it bolt up to the Cummins 4BT :confused:

I have the adapter and flywheel. The BH I think is available aftermarket with left mount slave cyl stronger than stock. Maybe Advance adapters?

most excellent for you, but I dont have a 4BT yet. ;) And every 4BT I have found doesnt have the adapter on it, nor any NV4500 that I have found has the stinkin' bellhousing. ggrrrrrr

You have one of each, OR you have one of each you are willing to part with?

Nice link, thanks ... I need vehicle specific info to work it ... more research first to nail down specifics I guess.

What's the transmission pattern on the ford side of that adapter plate? If it's a T19 you may already have what you need if you can use it with the Ford/BW small block bellhousing provided it's the same. Again, read the thread that I suggested before you toss an extra $700-800 on something that's almost impossible to find, the GM flywheel setup.
