Are you possibly saying the L70 engine was evaluated after it had been discontinued and once regular Camaro production had started?

Yes, kind of. The RPO was drawn and then cancelled per the timeline. However here is where it got interesting when a retiree told me "hey I was part of the L-70 build program".

In summary These were prototypes built in the same side building where the pilots were produced. These were 3X2 small blocks and were cosmetically dressed with the stripes later used on RPO Z/28. The build happened soon after regular Camaro production started in the fall of 1966.

Here is the Air cleaner image close up that I posted in another thread on this topic here back in 2016.
