    Posted: 02 Feb. 2012 at 1:01pm
I have just started working on a 1946 CJ2A.  I know without a doubt that I am the 3rd owner of this Jeep.  It was sold new here in Oregon. 

The body and frame serial number tags match--50749. 
The body ACM number is 40581.
The tailgate number is 40581.
The serial number on the Oregon title is 4T34114A.  The 4T3414A number is the one that is stamped on the front of the block above the water pump.  I do know that sometimes in the past the serial numbers listed on the titles were actually the engine serial numbers.

In all the research I have done, I thought the correct serial number stamping on a 1946 CJ2A engine should start with the letter J followed by 5 or 6 numbers.  The people that I got this jeep from assured me that this jeep had the original engine.

The block casting number is 641087-L-W10-AN1-OR-N2.
The head casting number is 6401XX (I can't read those last 2 numbers because the oil filter bracket is covering them and I have not yet removed that bracket).

Does anyone have any knowledge or thoughts on the strange serial number stamped on this engine?  Could this really be an original engine with these numbers?  Thank you for your input.

I'm not that knowledgeable but could the 4T be Willys' description for 4 wheel drive, the A for undersize main & connecting rods with 34114 being production number? Would this make it for a 1949? Not for a CJ2A? How about from a Jeep Pick up Truck? Just my thoughts.

Also i did check with the Oregon department of Motor Vehicles.
the title  with serial number 4T34114A and license plate were first issued in October of 1946.
the license plate on the jeep  is the original license plate  still on there.
I just wonder how a truck engine with the serial number 4T34114A stamped on the block
wound up in my jeep and on the original title  issued in October 1946.
IT IS A MYSTERY.

From this description I think the most logical answer is that Willys put an engine that was originally destined for a truck into yours. Why? who knows. Where do you think the term "Willy Nilly" came from?LOL

A quick yahoo search turns up this...
"Willy-nilly is actually a varition of "will he--nil he," which originally meant (and sometimes still means) regardless of whether or not a person consents to something. "
 
Besides that, i'm interested in this Motor conundrum as well.  lets see some pictures.

Hate to be a stick-in-the-mud, but:
  • "4T" is a 4WD pickup Truck engine number
  • pickup trucks were not made in 1946 (first made in '47)
  • 641087 block castings were not used in 1946 (first used early '47)
  • "W10" foundry castings first appeared late '47/early '48
The engine has been swapped.  4T engine number 34114 is from late '48/early '49.

That puts a twist in it. How did a Jeep get titled in 1946 using an engine number that didn't come out until 1948 or 1949?

That's what I was thinking so there must be some chicanery going on with the title. In other words, it's bogus.

It wouldn't neccasarily have to be bogus would it (?) that would imply it wasn't legal.
 
Just simply means the title was applied for (or updated) after the engine was swapped in. Still perfectly legal I would think.

Perhaps it was originally titled in 1946, engine replaced & title updated after engine replacement.

Taken from Oregon DMV site:

"CORRECTIONS AND ADJUSTMENTS
VEHICLE INDUSTRY REGISTRATION PROCEDURES
22.060 VIN and/or Engine Changes (CVC §§4161, 4163, and 9257)
Passenger and Commercial Motor Vehicles
• The department does not record engine changes on passenger and commercial
motor vehicles identified by a vehicle identification number (VIN).
• If an engine change is reported for a vehicle identified solely by the engine
number the identification number is changed to the:
— serial number, or
— an assigned VIN."

Maybe the title was originally issued with the original engine number, as we know many were, then when the engine was changed, the title was updated. I know that kind of stuff happened here in Colorado, at least. The first hot rod project I helped my Dad with was a '39 Merc V8 in a 33 Ford pickup. The "motor no." on the title had to be changed & resulted in a title for a "1933 Mercury Pickup".    BW
