Mystery surrounding my engine and chassis serial numbers

Humm pics not on this computer. I know when I bought the cj I did check the numbers and trans did match the body.

Pic of C6 where the partial VIN is stamped...

Fortunately the numbers were stamped a little more legibly on the transmissions vs the hard to read half A$$ job done on the engines. Unfortunately the location made a  while in the car read almost impossible. On the C6 it was stamped on a flat area on the main housing right in front of where the tail shaft housing bolts up.

No Officer...I really don't know how fast I was going, my speedometer stopped at 140!

Does anyone know what is this number stamped on the front of the block by the oil pan face? It is "111870"

That sure looks like a partial VIN to me, you too?

Let me check your shorts!

I am thinking it is the engine assembly date. Normally I would expect to see a "0 L 18" for November rather than "11 18 70", but since the engine casting date is "0 L 17" November 17, 1970. I am guessing given the location and casting date, it is the assembly date of November 18, 1970.

Hate to ask but is the block cracked from freezing right beside the oil pan rail? Sure looks like it in the picture.


When a man is in the woods and talks and no women are there is he still wrong??

On the subject of block stamping.
On the two spare 351C blocks I had picked up and looking carefully at the stamping, my personal opinion, being a qualified machinist having stamped many parts with id & s/n numbers. I believe that blocks would be stamped at the time they were first put on the line prior to any machining. An unskilled or sloppy person would very likely NOT hold the punch square or hit it hard enough. This would definitely cause most of the up-swell of the number being machined off during the facing process, resulting in a hard to read s/n number.
(I got s**t many times at first when parts were surface ground and the numbers lost!)
As for the transmission, mine is a top-loader 4 speed and the matching number was stamped on the top of the front mounting flange, so it would be very easy for the guy on the line to match block and trans..... if he could read the block number that is!!
As for yours, who knows what it is, definitely a sloppy job. Good luck finding the truth.

SO much going on with this car !! There are many ways I could go at this!

ONE you have to research and CONFIRM other NJ stamped motors of that time frame. (NOT 72/73 info) Because looking at the stamps OTHERS posted "that is not a #1" I have seen . (granted I know Dearborn cars) This will also allow for car built in NJ around that time frame and the first couple numbers. IF it was a Dearborn car from that time frame you would expect it to be in the 135-136 range. You probably know that.

TWO (as someone else said) What does the OTHER APRON show for the VIN? While the #4 is wrong is there a #1 on the other side?

It really is goofy - the combo of errors that is! The assembly day seems correct for the casting.
Look at the OTHER SIDE OF THE MOTOR (at the pad area of the stamped VIN). It is smooth or "all peened up" like under the stamp?? Can figure if that is rust or attempt to mask prior number. SEEING THE & at the end almost questions if that was missed?

Mark
P.S. If this was a $1200 buy in 1980 I doubt any if of any issue............what is the "rest of the story" on date of purchase, price and how it was represented by seller? (Dealer?/Restorer? someone that sells lots of cars or just a guy)
