Charlie's x 1968 copo 9737 yenko
 

What an awesome car! Beautiful!

What is COPO 9737?

From Muscle Car Museum, no verification of facts...

COPO 9737 Sports Car Conversion was considered to be done especially for Yenko to dress up his packages. Its biggest visual benefit was the 140-MPH speedometer. This was actually the same code the dealership had used for 1968 when they had swapped new 427 CI short-blocks in standard big-block Camaros, but COPO 9737 could be ordered by anyone who filled in the right spaces on the paperwork.


This is right from the auction and is probably a better descriptor...
COPO 9737, better known as the Sports Car Conversion option (named for Yenko Sports Cars), included upgraded cooling and brakes, along with a 140 mph speedometer, heavy duty springs, larger anti roll bar, M-21 close ratio four speed transmission and a 4.10:1 Positraction differential.

Are there any known 9737 non-Yenkos?

LOL.... "Yenko expert Charlie Lillard"

It is a great car though. Best running one I've owned.

Well, you did own the site.

Don't sell yourself short.
