67' mid year camaro BB copo
 

Does any one know of any info that may support copo installing 427s on the first BB camaros produced in may/june,to help yenko get 50 factory built; if nhra ever challenged his 54 list as being dealer installed, Is this how he was able to hit the 107 number in order to submit to NHRa, also what vins if any does 68' copo camaros have on engine? https://www.yenko.net/ubbthreads/imag...ns/worship.gif

Thanks JoeC, so he tried several times but couldn't get them the way he wanted, all dealer swapped. https://www.yenko.net/ubbthreads/imag...ns/worship.gif
