Strange vin #
the vin# on my 76 engine has a vin# with the last digit is a 9 the rest of the vin# is the same also the correct vin# is stamped in the block but beside this # V0729CKX. Maybe this was a Friday/Monday car. The complete vin is 1Z37L6S5445126 same on the frame. I have owned HER since 1985 no swap outs. Any info about car would help. On driver door tag same vin # with build date 8/76

I am not sure of the question.
The VIN as stated, 1Z37L6S5445126, shows it was the 45,126th one built.
The V0729CKX shows that the engine was assembled at the Flit plant on July 29th.
You state that the build date was 8/76 which would match with a july build engine.
and....what was the question again?
Edit: okay now I see, vin ends in 6, vin stamp on engine ends in 9. Does the VIN match the title?
I would have to guess that who ever was doing the stamping that day just got the 6 upside down in the stamp gang. What about the transmission, does it have the same mistake?

That's the assembly date and identification suffix for your engine.
V plant code for Flint, Michigan engine assembly plant
0729 date the engine was assembled at Flint (July 29th)
CKX suffix for an L-48 with auto transmission
V0729CKX was stamped on the engine at Flint before the engine was shipped to St. Louis.
The VIN derivitive on the pad next to V0729CKX was stamped on the engine at St. Louis. It should match the VIN on the driver's windshield post, but for you it looks like the numeral 6 may have been put in the tool upside down resulting in a 9 being stamped.
Check your transmission. The same stamping tool was used to stamp the transmission. It's possible the tranny will show the same mistake.

this is a pic with two vin#'s on the block. has anybody seen this before. the vin # ending with 6 is what matches the car vin #. thanks for the help on the trans vin # locate need to do some cleaning to find.
Never seen one that like that before. Mind if I ask around?

That certainly looks like the 'stamp guy' inserted the last digit upside-down and stamped the block...then tried to correct the error by stamping the correct number on it also. That operator would not have had any equipment to grind off the 'bad' number. Odds are the unit did not get tagged for rework and just got shipped 'as is'. Never seen one like that before, but you can tell that the same gang stamp made both number impressions (except for the corrected number). IMO, you have a bonafide 'oddball' engine block stamp that came that way from the factory. {either that, or the engine has a split-personality...}

The six got put in upsidedown and was stamped as a nine. When he saw the mistake, he put the six in correctly and stamped it again. The question remains: did he see the mistake and make the change before he stamped the tranny?
Unique to say the least.
Thanks for the pic.

99.999999% of undamaged engines do NOT need to be decked. What you see and measure at overhaul (and look horrible) is the way the engine was machined at GM. It lasted 100K miles with no issues, why farque with it now?

just took pic of trans, looks like the "stamp guy" tried to fix problem. 
look at the last #. going back stock you are right shouldn't need decking. just standard on my other engines thanks again for the input.
