1984 K3500 nv4500 install - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 4 door dually 4x4 454 4 speed that I want to drive more.65 is wound up. I have a 95 nv4500, the t-case in it, and also a 241c. My questions are...

What clutch combo do I use?

What is the best transfer case to use?

What bell housing?

Basically what all parts do I need to do it right?

I know some of you are going to tell me to research it and I have and most seem cobbled up to me. I want to hear from someone that has actually done it not someone who read about it somewhere. in the future I also plan to pull the big block and go with a 6bt. Thanks in advance.

If the 241 is out of the 95, it won't work. The output is on the wrong side.

There is nothing wrong with the 205 case that it would already have being a one ton. It can be adapted but the best route would be to find a round pattern case 205. they came in the K/V30s 85+. they will bolt to the rear of the NV4500 with much less effort. if i remember correctly the 95 was the transition year for the NV in gms. so yours should be modifiable to work with a cummins. that would require an input, retainer and BH swap to accomplish. with the gas engine clutch, you should be able to run a stock(to the '84 truck) hydro assembly if you run an Advance Adapters conversion bell housing. if you try to use the stock stuff you may end up with driveline clearance issues.

my setup is an old two piece rear main bbc. sm465 clutch assy with advance adapter bell housing. 85 slave and master with pedal assy.

had to clearance the inside of the bellhousing for the big clutch.
