Block Casting/Partial VIN Find

[daytho1]

Had an interesting find this weekend while I was doing some detailing.  I was doing some research on block castings, engine codes, and partial VINs.  According to the drivetrain info, the only block castings for the 67 L6 engines were 3877178.  Started getting really confused when I found my block to be what is suppose to be a 68 block (3921968).  The engine code matches my POP (F0626FM).  Some may say that the engine has been replaced and the engine code restamped.  I know for a fact that this isn't the case.  This is the same engine that came installed in the car in 67.  The only other numbers that are visible on the block are above the starter and adjacent to the transmission filler tube.  There are 2 plates: 1) CON2  2) 247.  I have no idea what those numbers could possibly be.  All of my documentation is original and I haven't bought a bogus POP.  Just curious if this could be a conflict with the drivetrain info.

Here's some additional photos of the additional tags.

"CON2" is the conveyor line the block was poured on at the Saginaw Foundry, and "F 24 7" is the block casting date (June 24, 1967). The "casting clock" shows it was poured during the 5th hour of the first shift that day.

John,
So how do I explain a 68 block in a 67?  Is it possible that with it being close to the end of the model year that a 68 block was used?  Or were blocks allocated by calendar year versus model year?

Thanks for the info. We don't have much L6 casting data so we didn't realize that.

Yup, the 3921968 casting must have been released at the end of the 67 model year. Not unusual for some changes to not be tied to the model year changeover.

It's mentioned here: http://www.camaros.org/drivetrain.shtml#BlockCast, now.

You're more than welcome.  Glad I could contribute something.  I still haven't been able to find the partial VIN but I'll keep looking.

I still haven't been able to find the partial VIN but I'll keep looking.

On 1967 Camaros, generally only the Z28 and SS engines had the partial VIN's stamped on the engine block.

Guess I'll stop looking then.  LOL!  Thanks Paul.
