351C block code question

There is a thread on my Cleveland forum about a 351C block and it concerns
the code stamped into it. I never paid attention to codes and such, I just
rebuilt what was good and threw away what was bad. So I have nothing to say
about this. Basically, the debate is to whether the "H" in the stamped
code, 2H182214, refers to the engine code (351C-2V) or the manufacturing
plant.

Any thoughts?

The thread is here:

Its a partial VIN. Ford did it on some cars/engine combos and didn't
on others. The two is the last part of the body type code (as in 02)
and the H is the engine code. The last six numbers are the sequential
unit number for the car itself just like the full VIN. My Boss 302 (G)
and my 428SCJ (R) motors have these partial VINs stamped on a pad at
the back of the block.

Ah, there is the problem. See the other post by the guy with the Boss 351
block. He has an F in the code. He writes:

"I had a Boss 351 car. The VIN of the car was 1F02R123456 (not really the
sequential build number). On the INNER FENDER (NOT the motor) was stamped
1F123456, which was obviously the year, assembly plant, and sequential build
number."

Since F was not used for any 351C engine type, his story has les. So, what
is the real deal? Is it that Ford was not consistant?

Just to add a little more fuel to the fire, I built my 400 with a 1976 D7TE
block, casting date 6D21 (Apr 21 1976). I know it was originally built as a
351M since I took the original pistons & crank out of it. Stamped into the
pad on the back of the block is 6J156560. So if the 6 is the last # of the
body type code it could be from a 66 (LTD Brougham) or a 76 (Country Squire
Wagon). However there was no J engine code used in 1976 according to my
FoMoCo shop manual. The 351-2V engine code is H as has been noted ad
nauseum. The only J code I could find was for the assembly plant (Los
Angeles).

Would it be unreasonable that each plant had its own method? I mean,
let's say that Ford sends out a memo mandating some VIN stamping on the
block to somewhat deter vehicle theft strips. It might have been up to
the guy with the dies as to how that played out, as long as they were
complying with the rule. Heck, it might have varied from shift to
shift.

Differences in small parts and underside color and whatnot from
plant to plant are documented. Why not the VIN, too? The fact that you
have different results in your group and this one pretty well points to
inconsistent policy. The sequential number is going to be the critical
part of the stamp, anyway.

Not only is this possible, it seems likely. But I was hoping for a definate
confirmation.

Yes, it sounds like a plant code.
