1969 COPO 427 engine

[Hawkeye]

Thanks for the info and the pictures. Can you tell me if your build date and vin stamp are both on the front pad of the engine?
The responses I have gotten are truely awesome. I greatly appreciate the information.

In his case yes they are.

But, is it possible for the vin to be stamped on the pad above the oil filter? If so, is there an approximate date when they changed the vin stamping location?
Thanks.

It is both a timing and a plant issue as Chevelles were built at several Plants. That early Yenko Block is correct. I'm certain that some of the Chevelle Guys can Chime in and help with the specifics.

Here is the best picture I have of the front engine pad. Please give me your thoughts. I know it is not the best but any info you can give me will be very helpful.

I'm no COPO expert,but that VIN does correlate with Baltimores build out schedule for April 1969.
Although the orange paint set in the font stampings would indicate the short block was repainted at least a second time after initial asssembly.
Is that threaded head plug overshadowing the Tonawanda stamping or is that just a bad camera angle?

[Hawkeye]

Thanks for the response. Is there any documetnation I can go by in order to verify this?

I would like to thank everyone who has given me some responses to all of my questions. You have been very helpful and I look forward to getting more information from you as my project progresses. This is one membership that is worth being a part of and you will see me listed as a member soon. I still need many part numbers and info on the L72 engine so any additional info you have keep it coming.
