GMC 4000 questions

[Mr.green]

I believe the model on the glove box tag was N 4005.

Its a 1963, 351C (??the C part??), 19,500 GVWR

I have a few questions. How hard is it to find engine and chassis/drive train parts?

I still can't find a picture of another one (I gave it some decent effort)

Any chance of finding new front fenders for it?

Current uses: hauling old cast iron wood working machinery within an hour or so from home. Cruising it through town once a week. Making my 4 year old boy grin ear to ear. Tow a tandem dual wheel trailer with more machinery on it.

Long term: Body work, paint, big cam cummins with an eaton fuller?? or dt466, some sort of modern drive train so I can make longer runs with it.














I think I am having a hard time talking myself out of it.

What you have there is a Model B. Other than the Fenders, the truck looks pretty nice. Fenders for it will be hard to find, although possible with a thorough research, but they look like they could be repaired. Engine parts are getting a little hard to find, but there are a few GMC sites out there that can help on getting what you may need. Driveline parts should not be much of a problem. That 351 should pull your full GVW weight with no problem. I once had a 4000 with a 305 in it and it pulled just fine, even when I was a little overloaded.

There is a little bubble on the passenger side door and cab front side part.

Drivers door has a tiny little hole, no bubbles. The cab floor is in great shape.

Owner has the original fenders that were on it, they were rusted out in the same places as well.

I am sure that they can be repaired.

I would leave the V-6 in there unless it has a serious problem. Swapping a big Cummins in there will likely cost far more than you would ever save gas vs. diesel, and be a tremendous headache anyway. About the only diesel swap I can think of that would turn out halfway decent would be a Duramax. B's were set up for V-6 (gas or diesel) power. A few did have 6-71's in later years but had a very large dog house. The gas V-12 versions had the engine mounted under the cab.

Awsome truck!! Find an old body guy who really knows how to repair body panels and match the paint.. Wouldn't touch the motor till it blows up.... and that might be a while. Get bigger tanks for those longer trips and enjoy what you have.
There are some parts available over on the 6066 site, as well as pics of other 4000's

The C stands for 6 cylinder ( weird eh? ). A big block 6 cylinder at that :P
