Help with Block ID

I read a comment where the engine serial number could be stamped in the transmission bell housing where its bolted to the motor? Doesn't seem helpful if someone swaps the motor :)
 
You might consider taking a head off and taking a picture. That will show what you really have. You should have an early Mercury motor in that truck. If you do do, it is a good one to use.
 
It's got a 59AB front crank pulley, and crab dist, out of all the replys I don't see anything about letter in the center of the heads like 59AB or the letter A Walt
 
I think I found part of the problem. Can anyone help me ID the year of this truck??

I was told it was a 1940 but after doing some more reading and looking around trying to figure out what motor this is it just dawned on me that it maybe a 1942. The headlights on heavy duty trucks changed to be mounted in the fenders ???

I'm at work, all the paper work is at home. I'm wondering if the old guy I bought it front just had it wrong??

apparently Snogo still has just about every record of every truck they ever worked on.

This truck had the snowblower mounted 6/8/43

So I'm going to go out on a limb and say its a 1943.
 
It may be wartime if it was military. I'd say 1942. FoMoCo only produced military equipment after early 1942. If it is all-wheel drive, it was likely a conversion. It may be NAPCO or Marmon Herrington.

Not any bearing on what block it has but is this truck four wheel drive, sits kinda high, are there any Marmon Herrington badges inside the cab and on the hood. It looks like there is a shadow where one badge would have been on the left rear side of the hood. Military 1942-45 trucks had four steel spoke steering wheels, only plastic perimeter.
 
this is a marmon herrington 4x4 The truck does have war tag and marmon tags in the head board.

Does anyone know how to get a hold of Don Chew from brighton,CO. Apparently he has all the old records from Marmon Herrington. The number i have 303-659-8884 is no longer in service. Hopefully this doesnt mean he has passed away. And if so, someone is taking up the torch to keep all that info alive. I'm surprised Marmon didn't keep it.

Still doesn't help ID the block, but at least it narrows it down some.
 
Marmon Herrrington & NAPCO both converted a lot of 1942 civilian equipment under contract after the war got started. A lot of civilian built stuff was rerouted to the war effort. Ford built a lot of G8T 1.5 ton trucks during the war but they had the 226 6-cylinder engines and a good bit of them were sent to the Soviet Union.

I'll do some more scraping on the bell housing to look for a 59. And I'll take a peak and look for head numbers or tag numbers.

The other strange thing about this truck is that its a LH drive truck, but all the gauges are on the RH side. Meaning the glovebox is in front of the steering wheel :)

Can anybody explain this???.... MARK
 
It has a cab from a RHD on it.

Truck, 1 1/2 ton 4x4 dump (Ford / Marmon Herrington)
8 cyl. 95 bhp. 4F1Rx2, 134" wb.????
A large number converted by M.H. for the US Corps of Engineers. Used on Alcan highway and Canol project.

Checked the registration, says 1940, correct serial number. Must have been a typo at some point who knows. I'm almost positive it's a 43 according to snogo paperwork.
I'll check the wheelbase at some point. Hoping to get motor out this weekend maybe. Then I'll know for sure what it is. Sounds like snogo trucks were rh drive so they could see better. Then someone must have switch the steering and pedals and left gauges, or swapped cab? The other concern im having is being able to get highway speeds out of the truck. Trying to leave it stock but also a frequent driver.
 
Anyone know the model of the 4 speed transmission they usually put in the trucks?

Was spraying all the bolts on the motor with Pb blaster, getting it ready for removal this weekend and noticed the drivers side head looks to have a crack in the middle length wise in the head. Pulled dip stick, has oil on the stick, but also looks like it probably has 2-3 inches of water in it also. Not sure if that's high enough to reach the crank or not.
So we will see, going in with low expectations lol.

On a side note the 4 speed that is in it whatever that is, do they make bellhousing to connect to say a 302? I'm assuming anything over say 150hp and you need to be very careful not to blow the ****** apart?
 
The 4 speeds are a little hard to drive, they are not synchronized like a modern transmission. Some people like to learn to drive them, but for most they are a challenge. Don't believe the original 4 speed is a very good candidate for an engine upgrade, strength is not the major issue, drivability is.
