1971 K10 Stepside - Getting a Roller Roadworthy

[pjmoreland]

I picked up an NV4500 yesterday. Bought it from a guy way out in the desert in eastern Nevada who pulled it from a 1993 2500 WT with a V6 about 6 years ago with the intention of using it in a project that fell through. He said the truck had a little over 100,000 miles on it. He told me this after I had paid him for it. Hopefully that is accurate. It spins smoothly in all the gears. That's all I know at this point. He included a couple of shifters and a couple of original bell housings. My understanding is that the original bell housing won't work because the slave cylinder hangs down on the passenger side and will interfere with the front driveshaft. He also threw in a bunch of old Holley carbs and parts. I don't think I'll be able to use any of them on my SBC since they are 850 CFM models. Traffic on the way back was pretty bad because Running Man just finished up.

This transmission is a 2WD version, so I will be converting it to 4WD by installing a new main shaft and tail housing.

Sweet Project, Sub'd to follow along.

Those leaf spring brackets look scary with those square tubes booger welded to the bottom of the frame! ORD makes some really nice stuff. I have their Shackle Flip hangers on the rear of my K5

PO was really rocking out with (2) 6x9's cut into the bottom of the doors.

I really hope those booger welds are as weak as they look when it comes time to grind them off. It's gonna take way more time to remove them than it took to make them.

I will be welding up those gigantic speaker holes, but on the bright side it made it very easy to reach inside the door to help roll up the sticky window.

That’s a nice haul. I didn’t realize you could get a V6 with a 4500, I always figured they were all 3500’s, and I also didn’t know you could get a 88-98 2500 with a v6. I learned a few things today.

I wasn't aware of that either. Based on what I can find doing a google search, the NV4500 was offered in the 88-98 W/T model, along with a V6, to increase the tow rating of the truck. Strange combo.

That is interesting. Must have been a slug when loaded up or towing anything with a V6.
I have a 4500 in my 93 and it's going strong at 150k. I did change fluid in it at 100 just because it seemed like a good interval.
It's a good transmission. It has always had a touch of synchro "bite" on the 1-2 upshift if you're being speedy, but that's minor and avoidable.

Is your first gear so low that you don't usually use it?

Installed the windshield. Usually i start at the top and work downward so that the corners are easy. This truck is so high off the ground though that it was too difficult to push up on the glass, so I started at the bottom this time. Those corners sure were a battle.

Post a clear pic of the barcode tag or tell us what the big letters on it are and we might be able to decode it. The later NV4500s had a more square shifter housing so this one is 95 or older.

I put my glasses on and it looks like the tag has GXB on it and my doc says this:

MODEL YEAR 1994 - 6.34:1 RATIO GEAR SET
4X2 C-TRUCK 15960760 GXB ALL EXCEPT 6.5D

It says GXB on the label. The guy I bought it from said it was out of a '93.

Yes, it's a true granny low. Nice for taking off with a trailer or 4-wheel crawling in LO. Or parking in a crowded lot.
That said, the shifter calls it L, so the 1-2 shift I was referencing would be the 2-3 to those of us that remember the old school 4-speed shift patterns.
