Most of the super camaro's were offspring of the Central Office Production Order or "COPO" camaro's, I know that the Yenko camaro was an offspring of the COPO 9737 Sports Car Coversion which was a 425 HP 427 CID iron engine, with a 140 MPH speed-o and Goodyear wide tread tires and 15x6 wheels, and Yenko added their exterior stripe kit and a set of gages to the interior, and created an icon, a camaro legend that would live forever as one of the toughest meanest camaro's ever built, a standard COPO 9737 was a plain looking car with no stripes or special interior amenities, in 1969 Yenko had wnet one step farther with the interior and embroidered a big sYc symbol at the top of the seat in the head rest, and you could not by any means mistake one of these cars for any other camaro.
There were a bunch of dealers that joined in the super car revolution of the 1960's, and a lot o the done very well at promoting their cars Don Yenko done a very good job at promoting his entry in to the super car revolution by hiring a driver who could get the job done, and show people the sYc camaro, in the process Dick Harrell would set many records in the sYc camaro, and prove it's validaty beyond the shadow of a doubt.
If that weren't enough a COPO 9560 simply called the "ZL1" camaro would hit the seen, the best purveyor of this car was Dick Harrell, Dick Harrell driving for Fred Gibb Chevrolet in the ZL1 camaro would set some of the most impressive times in the ¼ mile ever run in a factory camaro, this car came with an all aluminum 427 CID engine rated at 430 HP from the factory, the engine actually produced in the high end of the 500 HP range, and weighed only 30 pounds more then a small block Chevy, Harrell, with out a doubt did the best at promoting this car, he laid down a 10.36 to set his first record, and then later shattered that record with a 10.06, and this was a factory car that could be driven on the strett, although it was not meant to be driven on the street.
In the camaro realm of things their was yet another COPO package considered to be of super car proportions and that was the COOO 9561, which was a cast iron 425 HP 427 CID engine, yes of course that HP was underrated yet again, it put out the same amount of power as the COPO 9560 did, but weighed 300 pounds more, and was an impressive car also blasting the ¼ mile the mid 11 second range, making it a top contender for a title spot in the big race.
