I am looking into building a yenko/copo CLONE. I wanted to say that first so all the purest don't freak out when I ask these questions,. I am just looking into building a car with a lot of HP to have some fun in with my boyz ages 6 and 4.
First question would all yenko/copo have a X code??? the reason i ask is when I have done some reading www.holisticpage.com/camaro/camaros/copo.htm
the article references that "Since these cars could be ordered by any dealer there were many more COPO's built for other dealers
." Does that mean another dealer from LA could have ordered the motor and put it into a LA built car with out a x code??? Just a question. They raced these cars in CA. also right
Second question is that the article says that "The first COPO 9561 cars were delivered to Yenko Chevrolet in January, 1969
." That means to me that there could be a 1969 yenko/copo car made that would have been built in the NOR plant without a X code since X codes didn't start until the second week of December. I am sure the cars that he received in January were on the production way prior to the second week of December wouldn't they??? according to www.Yenko.net
. "Early cars were either X11 or X66, while cars built after March are X44
." early meaning early in the year of 1969 not early in the production year that would have been started back in sept of 1968.? So could have some of the first 1969 copo/yenko's built been without x codes?? We know that all 67 and 68's were without x codes. That is when the x codes started right?
Third question is what crank would they have put in a copo? and is that the same as a yenko/copo? I have read that it is the 7115 crank but, but i have also read that the 7115 was put into the ZL1 and is super hard to find. I have read that most copo/yenko cars had the 6223 crank. Along those lines the block would have been a 512 4 bolt main with 840 heads right???
Finally, could a copo motor been placed in other cars other than the ones that Don Yenko built? yenko and copo seem to be synonyous with each other. Is there any info of how many went to don yenko and how many went to other dealers? I am not a fan of the 6 colors that i have read about that Don Yenko's camaro's were. If there are ones that don did not get could they have been any color?
Once again guys i am just asking questions and have come to the table of the all knowing for a few answers. I am looking to build a car that my boyz and I can have a good time in yet CLONE it as close as possible. Thanks for all the feed back and look forward to hearing from you.
