I see people on-line questioning the 1965 COPO 9719 Chevelle 300 at MCACN.
Nothing wrong with asking questions as this 396 L-78 is not a Z-16 and is very unusual.
Questions need answers

Did some research on the 1965 Chevelle KAN trim tags

I found special order trim tags on Yenko cars starting back in the 1980s.
It took me a long time to collect trim tags back then to compare Yenko tags to the regular production tags.

I did the same process on the 1965 COPO 9719 Chevelle 300. It only took a short time to find trim tags on-line.
The 1965 Chevelle KAN tags use the numbered groups 2 to 5 option code fields.
The first tag is from the COPO 9719 and has what looks like a special order number in the group 5 field.
The second tag is from a Z-16 and has a "M" in the group 4 field. The "M' code is known on Z-16s.
The 3rd tag is from a regular 1965 Chevelle and has a "W" in the group 5 field (seat belt code).

I have not seen any other tags with the number like the 1965 COPO 9719 Chevelle and I was able to find a lot of 1965 KAN tags.
