This 2014 Z/28 relates perfectly to the Double-COPO.

My original statement " I don't think GM ever viewed the ZL1 to be a corner bender, it was to be an all-out street/strip car during the 'muscle-car wars'." should likely have read:
"I don't think GM ever viewed the original 1969 ZL1 to be a corner bender, it was to be an all-out street/strip car during the 'muscle-car wars' of the late 1960's and the early 1970's."
I would check around some of the muscle-car sites on the original ZL1. While the 1969 ZL1 had the F41 heavy-duty suspension, their intended purpose was for NHRA drag racing. Indeed, I would say that the 69 ZL1's that were built likely ended up in the hands of drag-racers (e.g. guys like Bill 'Grumpy' Jenkins).
It is possible some of them ended up in road-race applications, but likely would have required a rear-axle ratio change.
I would also note the 1969 Z-28 had the JL8 option which enabled someone to order a 1969 Z-28 with 4-wheel disc brakes. I am not certain how many ZL1's had this option (or whether you could even order it on the ZL1).
