Name COPO can appear ridiculous for a car of this type, but the connoisseurs know that these 4 letters are power synonymes to the pure state!
COPO corresponded to the initial ones of Central Office Production Order, the department Chevrolet for the productions "to leaves" such as the Taxis, the Police cars.. but also the cars "to the card" as a Muscle For on measures!

The COPO Camaro had, mostly, the BB 427 of 425HP, nevertheless , some Camaro received the Absolute weapon of Chevrolet: the BB 427 ZL1 all alu. It was a true dragster!
Vince Piggins, the director of the promotion produces Chevy had to show a lot of diplomacies to induce this department in a production program of Great Stock.

The ZL1 and the Camaro 427 some melted became lance iron of Chevrolet in Great dragster Stock. To the red fire, the extreme discretion of the Camaro 427 did that she surprised a lot of people.

In contrast to the other Muscles For that sported ªcussons, enjoliveurs and aggressive dªcos, the COPO remained temperate while not sporting no special sign. Even if they figure among the Muscles For the dearest ones most never most produced, they almost all were delivered in a single color , without monogramme, or adhesive and other chrome, the interior also was stripped for him: in a COPO, invested money is located UNDER the cover!

Chevrolet finally produced can COPO, it is necessary to specify that the production includes for a good one leaves Chevelle 427 and Nova SB LT1 360HP 1970. These COPO did not doubtless generate the least profit for GM, indeed even sales to loss! But the objective did not be to win money, but to attract the potential customers with the concessionnary GM.
Historically this was thanks to the one of these concessionnary, Gift Yenko, a man of which the passion for speed and the influence with Chevy played a role determining, that naquirent the COPO.

The Muscles For occupying a choice place on the market, certain concessionnary were themselves even specialized in this vehicle type as Royal Pontiac (Michigan ) and Fred Gibb (Illinois). They always tried to elaborate this that did itself better in Hot Rod of series. But the undisputed leader was Gift Yenko, that, what's more to expose the models more powerful , some made again more powerful himself!!
Yenko Chevrolet devint the temple of the Great one For.

Gift was himself pilots and his first realization was the Corvair 1965: the Yenko Stinger

In 1967 apparut the Great Camaro Sport SB 350 , then vint the 396 395HP. With each of its motors, the SS was a true rocket, but as always, certain persons some wanted more. Now Chevrolet reserved the 427 to the Corvette and forbade itself the installation in an inferior model to the... impala Not Gift Yenko! If that returned, it was necessary to do it.

The first Camaro Yenko was a SS 350 team of the L72 427, Yenko the ªquipa also of wheels "special rallye" and of lateral exhausts of Corvette. Some monogrammes completed the all.

If the SS 350 were impressive, the 396 were fantastic but terrifying.

In 1968, the inspired idea of Yenko to propose a Camaro 427 fit school with of concessionnary others of New York to THE and brisa the taboo of the Muscles For with Chevrolet. This is as well as naquirent the COPO in 1969 , essentially thanks to the Camaro.









Vince Pinggins, another man of Chevrolet at the head of the Development Office Produces and Gift friend Yenko, s'intªressa itself closely to the project and in was the principal craftsman while returning this car more accessible, especially for the amateurs of Great Stock.
Vince passa orders of some special Camaro with the Central Office of Production of Chevrolet:

- Melted Block 7.0 liters L-72

- High Ignitions Performances

- Transmission 4 reports Transmission 4 reports

- Bridge 12 bolts in 4:10 or 4:56 Bridge 12 bolts in 4:10 or 4:56


This car is known as a COPO 9737. For the purpose of the year 1968, 64000 427 Camaro had been produced in the framework of the program COPO. Chevy rediscovered itself to the avant-garde one in competition Stock and Great Stock.









The Camaro was rejoined next by a new weapon: the Nova 427, fruit of a concessionnary other Chevrolet: Fred Gibb and of a legend pilot: Dick Harrell. This Nova returned again competitive Chevrolet in the category "Automatic" in Dragster.






If the 427 returned happy everyone, Chevrolet do not s'arr’ta itself there and surpassa its competitors with a COPO to BB all alu: the Camaro ZL1 named 9560!

- Block in Alu Block in Alu

- Melted Shirt

- Track and special axes floating Track and special axes floating

- Raised soupapes: 14.70 adm. and 15.748 ªch.

- Cylinder heads alu Cylinder heads alu

- Compression Rates 12.5:1


This motor could resume the indestructibles connecting rods and standard vilebrequin of the 427 bottom.

The difference did itself at the level of the weight: L72 + 315KG, ZL1180KG!

As the Corvette, the Camaro had become an essay bench rolling for the high pieces performances.

With the weight and the systems of a SB but the power and the couple of a BB, the ZL1 was monstrous. But the prohibitive tariff fit that only 69 unities were ordered.

During this time, Gift Yenko continued to prepare its own Camaro but on the basis of the COPO, it personnalisait the interior and the exterior one.

Yenko s'attaqua itself also to the Chevelle in personnalisant the Chevelle COPO 427. The Chevelle COPO 9562 left the assembly chain with the drank 4 Muncie, be with Turbo Hydramatic 400, brakes av to discs and a bridge 12 bolts 4:10

1970 marqua the end of the Camaro COPO to BB, it remained only the Nova COPO 350 SB 363HP: 12S to the 400DA. Gift Yenko s'attaqua itself therefore to the personnaliser.

The end of the Muscles For arriving, the motors BB to high compression disparurent, but Chevrolet do not n'abandonna for as much his quest of performance and Gift Yenko itself there associa all naturally.







Shepherd chevrolet of Big Rapids (Michigan) Was a concessionnary other assistant to bases COPO. It was most concessionnary oldest Chevrolet of the USA (1925). It was to the just era behind Yenko, but it always exists!






If the COPO disparurent, the will of Chevrolet to produce athletic cars of exception of s'arr’ta itself not. In 1970, Chevrolet installa the BB 454 LS6. Dautre leaves Chevrolet installa his "bigger SB "in a Nova 1970, the 350 Turbo Fire of 360HP.
Well evidently, Gift Yenko itself in m’la!






At first years 80, Yenko has gone out his last Great one For: the Camaro SB Turbo Z





Even if the production COPO disappeared, Chevrolet not some stops less than to make performance extremist Camaro such as the Iroc, Z28... j'usqu'en I j'usqu'en 2001 for 2002 sounds the glas of the Camaro and of his cousin FireBird!!!

Looks like some of the shot's were taken digitally from the American Musclecar "COPO" episode on Speedvision. Thanks for the translation above. The loose translations become pretty funny at times..i.e. "- Melted Block 7.0 liters L-72"...god I hope they meant forged.

I was kinda hoping they meant cast. [img]/ubbthreads/images/icons/smile.gif[/img] That would be the biggest forging press I've ever seen. [img]/ubbthreads/images/icons/wink.gif[/img]
