1957 GMC, Chrysler OR 1978 AM General 6x6 Deuce

1957 GMC Duce 6x6

I know the thread title is confusing, but so is my problem.

I found what the vehicle title says is an M35 1978 AM General, Owner says is a 1957 Chrysler 6X6, and pictures say is a 1950's GMC 6X6. He says it has a 354 hemi engine, 4 speed with granny gear, and 2 speed transfer case.

I want to go take a look at this truck today, but I'd like to know what exactly I'm looking at so I can haggle a little better. Any insight would GREATLY appreciated!!

I think it is safe to say that it isn't a 1978 AM General.

Agreed...Also safe to say it's not a Chrysler either!! Maybe the owner is just referencing the engine?

 

[doghead]

I think I recall someone else posting an old truck with a hemi(industrial) that was a transplant.

What it is: G-749 series GMC

Sounds like it could have an early Chrysler Hemi 354

What it is not: an AM General


Titled one way; in reality, something else. Still worth checking out.

Heck, I would be interested in the engine.

It shouldn't be hard to tell if its a inline 6 or a V8 . Take pictures of the motor .

100% agreed it's not a 78' LOL. To me it seems like a 1950's GMC M135 or similar model with a Chrysler Hemi transplant.

Here's a copy of his add.......

1957 Chrysler 6 by 6. 354 hemi engine. has a flat bed. 2 speed transfer case. its an old military truck. reassembled in 1978. has heat. windshield wipers enclosed cab. can pull a house down. excellent in pushing snow in long driveways. very heavy. 4 speeds trans with granny gear. air over hydraulic brakes. pedal low on brakes but they work well. starts up and runs this thing is reliable and works every time. Title says its a 1978 am general air operated front differential.

Currently running off of boat 5 gallon gas tank. 2 fuel pumps cherry bomb exhaust. Sounds cool. huge radiator, new starter. It has good matching tires, mud and snow. red light on top works. nice mirrors pintle hitch in rear.

also have 2 wheeled camo trailer. military type.
weighs approximately 13,000 pounds."

For the price, I think this might be too good to pass up......

If the price was right, I'd be on it like a hobo on a ham sandwich.

No disrespect to hobos or ham were meant in the comment above.

$2500 for the truck $450 for the trailer is what they are asking .

So the original engine would be the inline 6 GMC Gas. Are they hard to find? Cause I have a 66 Charger that would just LOVE to have that Hemi living under her hood
If not, I've got a 350 4bbl Torque Monster I can toss in the GMC and put that hemi in the Charger.

As soon as I get up there and have a look and a drive, I'll take & post pictures.

^ what he said

 

[porkysplace]

It originally had a 302 inline 6 with a automatic transmission.

 

[doghead]

And no high low t case, right?

The ad says 2 speed transfer case with air shift front axle . Wonder if they put a GMC body on a M35 frame and drivetrain.

Edit ; You should get some pictures of the axles also .

 

[M1224]

I was thinking the same thing about the frame..... Could explain the title..

Hmmmmmmm, M35 Frame, GMC Body, Chrysler Firepower Hemi........ It's the Frankenduce!

I'm taking as many pictures as I can, of every detail I can.

 

[doghead]

Should be easy to identify, old axles are not top load double reduction.

 

[Section8]

Ok. I don't claim to be an expert but...
Looking at the pictures, side profile, you can clearly see that the front drive shaft its completely horizontal meaning top loading axle.
To me this says axle swap or the owner has put the body on a newer frame.
Going along that line. Since it is gas, could it not be an REO 6x6?!
Pictures of the axles and driveline will be very interesting to see!!
If they only did an engine swap and front axle swap with the air locker, I would be concerned about two different axle gear ratios if the rears weren't swapped also.
This calls for catasrtophic failure in the drive line!!
Just my two cents take it or leave it!!
All this aside I would be all over it if everything checked out!

If it is titled as "assembled" it should have a state of michigan vin tag rivited to somewhere . If it is 1978 AM General look for the vin numbers on the frame by the front spring mounts.

It doesn't say anything about an air locker?

Looking at the middle pic, the axle is off an M211
