What to look for when looking at a COPO???

[Unreal]

Virtually all the COPO "indicators" can be added to any car. As William stated, the COPO and the L78 shared most of the HiPo stuff, so if the original engine is gone, it's hard to prove. If the car is unrestored, and has the "indicators" and the original cowl tag (a lot of if's) AND has X22 or X66, it would most likely NOT be a COPO. So if it has all the indicators, and X11 or more likely X44 on the tag, I'd be getting excited. I think one X22 COPO has been found, and no X66 non-Yenko COPOs found.
