I think CamarosRus' question means, the stamped locations should have the same alpha numerics and number of digits since they were stamped at the same time using the same gang stamp....all EXACTLY the same. . So a genuine factory stamping mistake would be on all locations? . ~ Pete

The partial VIN will be a smaller stamp text size.

I think you're referring to how the partial Vin stamp is smaller than the suffix/date stamp? . All partial Vin gang-stampings should be the same as each other since the same tool was used on each location. ~ Pete

You'd think so

It's unusual to find either an engine plant stamp or an assembly plant VIN stamp where the characters all have absolutely equal depth and definition; there were many variables involved in the length and wear of the individual dies, angle at which the holder was held, direction of the hammer blow, etc. Many restamps, however, are "perfect".

Good example w/ this '73 unit shown....I can't figure out how to include pics? . Anyway, all 9 digits are on this example engine pad shown so would be exactly the same on the rest of the stamped partial Vin locations. . If one of the digits was upside-down or missing it would be the same on all other stamped partial Vin locations. . With the subject thread car missing the first two digits, if genuine the other locations should have the same mistake. ~ Pete

Re: 70 RS Z28
 

Same with this 68 Camaro. 2 sizes of stamps. So there are 2 stamping dies that are used.

Partial VIN is "18U199887"
The partial VIN can also be on the oil filter flange instead of on the pad with the engine code.

The 70 should be stamped on the pad and by the oil filter flange. Where the 68 may only be in one of the 2.

Re: 70 RS Z28
 

Yes we know the engine/suffix stamp is larger....it's the partial Vin only that I'm referring to. . Aside from user quirks, all locations should be the same exact stamping, mistakes and all. . The subject car needs other partial Vin locations viewed to compare to the engine pad w/ missing digits. . Thanks! ~ Pete

That is totally incorrect for a 1970 stamp. 70 does not indicate 1970.

The correct stamp would be: 10N567890
1=Chevrolet
0=1970
N=Norwood
567890=Sequence number.

Your example is very wrong.
The engine you posted did not come out of a 1968 Camaro. No Camaros were built in Lordstown, Ohio. That motor actually came out of 1969 passenger car. "HK" was used in 1969 to designate 350/300 with powerglide. The number before the "U" is a "9". "U" is for Lordstown, Ohio. Passenger cars were built at Lordstown.

Also 1968 Camaro VIN's started with 300001 and 1969 Camaro started with 500001. So that motor never came out of Camaro.

Also I have yet to see a 1968 motor with the partial VIN stamped in the rough casting by the oil filter.

I meant 1 where the 7 is. Blond moment.

The picture and info about the 68 was from a tag site. My only intention was to show the 2 different font sizes.
