Cummins to early GM NV4500 - Pirate4x4.Com : 4x4 and Off-Road Forum

Well I finally got around to doing a Chevy/Cummins swap.We put it in my brothers 67' K20.The question is can an early GM nv4500 be used? We already have one and need to get this truck going.He prefers to keep the lower first gear and we need to use GM trans so we don't have to swap out the tailshaft to run a 205. Any info would be great.

Kyle, you going to run one of the adapters from a P30 van? That would probably be the easiest way, but it tilts the engine.

Will that work? I heard that they would work,but AA said there was no way to make it work.I have had AA tell me other stuff that wasn't accurate though.

I am using a GM nv4500 (1996) All you have to do is change the input shaft to a Dodge and use a dodge bellhousing clutch etc..then you can use a CTD to Dodge nv4500 adapter plate (factory stuff)

You can't install a dodge input in an early GM nv4500.

In the Advance Adapters NV4500 instruction manual (page 4) it states "..this input shaft cannot be interchanged with any other NV input shaft other than transmissions with the same 1 st gear ratio UNLESS you change the counter drive gear also." So in your case it can be done with some extra work. I hope this helps you.
