Any way to find this out? ...

This is interesting but on my car - an LS-1 - my engine code is "G" not "X" - is this correct? also my production number would be 151460 - no way they built that many.

Some links with info. Not sure how correct they are

http://www.autofacts.ca/classics/vininfo.htm

This one lists all the option codes

The links don't really tell much new just confirm that the last 6 digits are production #'s??

My last 6 #'s are 230751

After some more searching I found following about Vettes.

Each VIN number is unique to that Vette
The VIN is assigned, in sequence, during vehicle assembly
The last 6 numbers of the VIN is the production sequence number, this is what makes the Vette unique
The production sequence number starts at one and keeps going
The VIN number is stamped on serveral location of the Vette frame for theft recovery
Some production sequence numbers start with a special number, the ZR1 starts with 800001
1953 to 1956 the VIN sequence numbers started at 1000
From 1960 to the present the VIN sequence number is stamped on the passenger side of the engine block
1963 to present Vettes VIN's have a digit for coupe or convertible
In 1968 a Federal law stated VIN's must be visible from outside the vehicle to benefit the police
In 1972 the engine code was added to the VIN
In 1973, 4000 VIN's were missing so production is 4000 less than the last sequence number
In 1981 a 17 digit VIN number was made the standard by auto makers around the world
In 1981 Vettes were built in St. Louis, Missouri, and Bowling Green, Kentucky, for a two month period. Note: The VIN's for the 1981's built in St. Louis use a combination of the orange and red tables below
