1967 Camaro Convertible L78 MQ Block 124677N221349

[jbtech]

I decided to order an NCRS report on the MQ block in my garage. My first request for a coupe vin wasn't in their system. Tried again with a convertible vin and got a hit.

With 113 L78 Convertibles in 1967, I was told this block is too late to be a pace car?

Anyone have any idea what car this may have belonged to?
