			here is an interesting article on a COPO 
 this looks like about 1964 or 65
 
 As far as I know, The first use of a COPO to build a fleet of race cars was the Yenko COPO on Corvairs
 
 Yenko used Corvair COPO 9513A and 9681E and others in 1966
 
 there was a COPO 9719A  1965 Chevelle with 396 L-78 and other hi po parts that was not a RPO Z-16
