Here's the Kansas Copo engine thread from a couple years back that Anders is referring to..
There's obviously controversey over the stampings but nothing is conclusive so the noted Vin worth comparing w/ the Vin of Roger's car..

Here also is a Team Chevelle thread w/ the same engine topic..

Keith, do you recall if your friends Copo had the 72/72 or '--' on the tag?.
And again is the 'L' on any known Copo Cowl Tags or only on SS cars?.
Too bad the original rear is gone as it'd sure clear up some info!.
And Roger, what was the answer on the POP existing or is there any chance there's any paperwork w/ POP imprints still around as it'd probably have the rear code too?.
