COPO / ZL1 Questions

[71SS]

I'm new to your site. And have some questions regarding COPO and ZL1 Camaros.
COPO = Central Office Production Order???
Were all COPO cars 427's?
Is a COPO car the aluminum 427 (ZL1)?
Were there COPO Chevelles and Novas?
How many COPO cars were built?
69 ZL1 Camaros and 2 Vettes?
I'm familiar with the Yenko cars, kinda, but I don't know what a Yenko Duece is.
Are there production numbers available for Yenko, Baldwin Motion, Nickey and Harrell?
Were there other GM dealerships that built Supercars? /ubbthreads/images/graemlins/dunno.gif
Hopefully one of you pros can steer me in the right direction. I've always been fasinated with these cars but never could find anyone that knew them well.

Help
