1972 convert engine pad question

[Joseph U.]

I have just looked at a beautiful red 72 air convert. the engine pad stamping is as follows:
12sxxxxxx (the last 6 numbers match the vin on the window plate but I don't understand the "1" before the 2S.
the other number on the block seems to be VD923ckw.
this car is a 4 speed convert base engine with PS not PB.
Can anyone help with the decoding of the engine stamping?
Thanks for the help.

just found out one of the engine cylinders was re-sleaved several years ago.
How concerned should I be - car seems to run just fine, does not burn oil and no sign of leakes.
Thanks again

The VIN stamping with 12SXXXXXX is normal for a 1972. The Date and Suffix code should read V0923CKW or Flint Sept 23 day 350CI/300HP 4-speed

Re: 1972 convert engine pad question

The 1 at the beginning of the VIN derivative is normal for a '72. The other stamp probably reads V0923CKW. That translates to an engine built in the Flint MI engine plant on Sept. 23, base engine with 4 speed trans,

One other thing, I'm guessing the "2" is, and should be a "Z".

1972 Corvette 350 CKW was a 200HP.

Yes. The engine code and suffix identify the engine. The VIN derivitive stamp identifies the car in which the engine was originally installed.

No, should be a '2'.

Thanks Mike. That's right. I was thinking of something else.
