The Term "COPO"

[JoeC]

The term COPO was not coined by the car magazines. It is shown in many Chevy documents. The way I understand it, COPO was a process used to order options that could not be ordered using the normal RPO process of ordering options. For example - you could have ordered a 1969 Corvette with RPO ZL1 but it was not available on a 1969 Camaro. You could have ordered an Impala with RPO L72 but RPO L72 was not available in a Chevelle or Camaro. The COPO process was used to build hi po cars that Chevy didn't really want to build. Some COPO options were parts such as the 1971 style spoilers used on a few 1970 Camaros, but more often they were combinations assembled to build a complete vehicle that was then given its own COPO number. For example, you can order a 69 Camaro with RPO Z28 and it optioned the car with the 302 engine, front disk brakes, 12 bolt rear, and other hi po parts that were mandatory with RPO Z28. It also prevented you from ordering certain options such as AC and AT. Now here is where the tricky part is that got the Chevy gear heads all excited. NHRA required a minimum of 50 factory built units to qualify in Super Stock class drag racing. Fred Gibb wanted to run a Camaro in Super Stock. He ordered 50 Camaros and he wanted to run the ZL1 engine but it was not available as RPO ZL1 so they put in an order for COPO 9560 to have them built. Like RPO Z28, it was a combination with mandatory options such as alu 427 and special BE rear, etc and also made other option unavailable such as AC. Fred Gibb had used the COPO trick the year before to get 50 special L78 Novas with TH400 trans that was not normally available with the RPO L78 option.

That was a great explanation by Jim and Joe. One thing I am unclear about, though.

Did the boys at Central Office use the term "coh-poh" when referencing any of the cars that were ordered through the COPO process?
I understand the point about COPO9561AA or whatever, showing up on the paperwork, but that does not mean that back then, they were referred to as "co-pohs". Most cars were ordered through the RPO process, and RPO showed up on the paperwork, but I've never heard of them referred to as "Ar-pohs" or "Ar-pee-oh's"

Jim was there so he can answer better then me but I believe the term "coh-poh" was started by the magazines in the mid 1980s. Before that most of the magazines said factory 427s did not exist. I never liked the term "coh-poh". I like to call them 427 COPOs. Some dealers ran ads in 1969 calling them "factory built 427 Chevelles and Camaros". A guy I know who worked at a dragstrip in 1969 calls them "425 horse Camaros". In Jim's post above he called them "factory hot rod" which is a good name because the hi performance COPOs were literally built to race. In my opinion Chevy would have never built them if it were not for the NHRA rules. They tried to keep them low profile with no 427 emblems or even SS emblems except for the 1968 Nova TH400. The 1970 LT1 Novas didn't even have any SS body parts. The 1970 Camaro COPO spoilers were pushed through so they can be used on the 70 Camaro Trans Am race cars.

I got to thinking after reading this post. You really have to thank god for racing. What if the different race organizations such as NASCAR, NHRA, AHRA, etc. had not made minimum production rules on certian cars to be raced in a particular class? We would never have had cars like the ones that we love so much and focus on in this board. Or you would never have cars like the Superbird/Daytona, or the Ford Taledega, etc. Just an interesting thought. [img]/ubbthreads/images/icons/smile.gif[/img]

I think our hobby would be non existent if not for the racing organizations. These are the reasons why the manufactures did what they did with these cars and without those organizations, we would likely have nothing. Just look what they have done for the trucks in recent years.
