The Boss 72 Chevy 4x4 Cummins Dually

[MrBeast]

Hello everyone, I am new to the group, but I am a long time gear head. I decided to send in some pictures of my current project a 1972 Chevy C-30 Dually.





I bought the truck out of a little town north of Phoenix AZ, I flew out, picked it up, and drove it right straight back. The truck is really solid, and has very little rust being an arizona truck. Allthough from what I can gather about the history of this truck, it probably has over a MILLION miles on it.

The truck has been built a couple of times, a custom duck tail spoiler was grafted into the back of the cab. As well the truck has a custom built towing body on the back of it. But the most interesting thing about it is the truck is that it has the SM465 4 speed, and a 3 speed Over/Direct/Under drive box mounted in behind the factory box under the bed. It is controlled by a remote stick shift setup, it is a interesting setup to say the least.

However Friday as I was out running around town doing some errands, well I stuck my foot in it, and the 454 up and threw too much power to that Over/Under box, and tore the U-joint apart, unknown yet if any internal dammage has happened to the box. On the up side though, I do have a NV4500 just waiting in the wings to go into the truck, as well I have the Advance Adapters Bellhousing, and a Centerforce Dual Friction Clutch.

So over the course of the next week here, I will be getting the tranny installed, building a custom cross member to mount it, and then getting the drive shaft I got with the transmission shortened to hook up to my old H072 rear end.

The rear end will be another future project, it currently has 4.56 gears, and I want to swap them out to 3.90's so as that I can maximise my gas mileage, this is a towing rig after all.

Right now I havent decided if I am going to stick with the custom towing body, or if I am going to sell it in favor of a brand spankin new body built to my specs, we will see on that, but for the time being, I did just install all new LED tail lights in it, and I am going to put new doors on the boxes, with hot rod door latches so as that they will latch nicer and seal better keeping everything inside clean.

As well I will be going with a vintage air unit, and plugging and smoothing most of the holes in the fire wall. Once all of that is done, I am going to tear the truck down, ship the cab and body off to be painted, and I will strip and clean the frame, and box it the whole leingth to make it much stronger, including building new cross members all the way down the frame that will be built much stronger than the stock frame is.

At this point I am going to rebuild the suspention, including either a 4 link or truck arm setup in the rear. The H072 will also get as I mentioned earlier 3.90 gears and an ARB air locker. I am attending college, and later on once I am in the Machinists portion of the class, I am actually going to make a custom set of hubs for my front and rear axles to accept 10 lug wheels, and then the truck will get a set of 19.5" Alcoa dually wheels, wrapped in Michelin Rubber.

On the inside of the cab I am working up somthing special as well, I am doing a custom digital dash, and I will be installing air ride semi style seats.

Other goodies I might have forgot to mention are under the bed I am going to be building custom fuel tanks out of Aluminum that will hold 95+ gallons of fuel. This will give the truck over a 1,000 mile range at 12mpg!

Anyhow, here are a few more pictures, I will keep you all posted on the project.

Oh also on a side note, I am going to be setting up a new shop here pretty soonish as well, so I am going to probably be posting pics on that as well (I am actually with out a place to work right now, it sucks!)
