Few muscle cars are as legendary and highly sought-after as the 1969 427 COPO Camaro.

Many enthusiasts consider the 1960s the golden years of the muscle car era. After the original Ford Mustang of 1964 became a smashing success, almost every Detroit automaker wanted to have a model in the pony car segment. Chevrolet introduced its fighter, the Camaro, in 1967. By 1968, the Chevy Camaro Z/28 was already running circles around Mustang 289s and 390s in the SCCA's Trans-Am racing series. But at the drag strip, Ford's special high-performance versions, including the 1968 Ford Mustang 428 Cobra Jet (335 hp) and 1967 Shelby GT500 Mustang with a 390-cubic-inch (7.0-liter) engine (335 hp), had the upper hand.

With muscle car wars in full swing, hardcore gearheads, road racers, and mostly drag racers wanted Chevrolet to respond. Unfortunately, it couldn't with its hands tied by GM's infamous racing ban of 1963. Some Chevrolet top dealers devised a plan to circumvent the GM limitations using the COPO system. The system enabled them to secretly order more powerful, street-legal Camaros from Chevrolet, already equipped with big block V8s and not upset GM. These drag racing muscle cars are popularly known as the Camaro 427 COPOs. Here are ten things only serious gearheads know about the Chevrolet Camaro 427 COPO.

Two visionary Chevrolet dealers, Don Yenko and Fred Gibbs masterminded the creation of the 427 COPO Camaros of 1969. While Yenko had personally swapped stock engines in the Camaro for big blocks before, he was having problems keeping up with the demand by 1969. His customers also wanted him to offer the standard G.M 5 years/50,000 miles warranty.

Initially, only these two dealers managed to order the base model Chevrolet Camaro with a factory-equipped 427 cubic inch engine. The Yenko Camaros had a 427 cu in L72 V8 engine, while the Gibbs' Camaros featured a lightweight all-aluminum 427 cu in ZL1 engine.

Chevrolet's high-performance Camaros of the late 1960s were among their day's most potent muscle cars. Despite this, racing customers still wanted faster, more powerful versions of Chevy's muscle car they could take to the dragstrip without further modifications.

Many of the 427 COPO Camaros orders of 1969 were mostly for customers who wanted to use them for drag racing.

The COPO (Central Office Production Order (COPO) was a mail-order system that allowed dealerships to order cars and trucks with non-standard colors or features. Dealerships often used it for special purpose vehicle fleets like taxis, school buses, company trucks, and police cars.

For 1969, stock Chevrolet Camaros were not allowed to ship with engines larger than 400 cubic inches. Fred Gibbs and Don Yenko exploited the COPO system to go around this. Additionally, through the COPO system, they could add high-performance extras not obtainable via the standard Camaro order sheet.

To secretly obtain these unique Camaros with 427 cu in V8s, these Chevrolet dealers used different special COPO codes. Camaros ordered by Gibb Chevrolet used the COPO 9560 code. Apart from the ZL1 engine, their high-performance package included a custom ducted hood, two exhaust systems, J52 Power Disc Brakes, and a heavy-duty F-41 suspension.

The 201 units made per the Yenko order used COPO 9561. In addition to the iron-block L72 V8, they got the same extras as the ZL1s and a few custom badges and stripes. Many of the Yenko Camaros and three ZL1s also got another COPO 9737 Sports Car Conversion. It added a 140-mph speedometer, 15 x 7 Rally wheels with E70 raised white lettered tires, and also had the option of bright exterior trims.

The 1969 COPO Camaros had such understated exteriors that few people could guess they had the enormous 427s crammed under their hoods. The iron-block 427-cubic-inch L72 V8 engine propelling the Yenko Camaros produced an impressive 425 horsepower and 460 lb.-ft of torque. Yenko would install a new set of headers and a freer-flowing exhaust system to boost power to 450 hp and 460 lb.-ft.

The Fred Gibbs' orders had an all-aluminum 427 cubic-inch V8 developed for the Can-Am Racing. Codenamed the ZL1, it was the first aluminum big block engine Chevy ever used in the Camaro. Chevy advertised the ZL1 as producing 430 horsepower and 450 lb-ft of torque. However, it had understated the figures to avoid attracting GM's attention - actual dyno tests showed the ZL1 was capable of a tire-shredding 550 horsepower!

Due to their remarkable performance, the 1969 COPO Camaros were immediately recognized as a formidable force on the drag strip. With about 20 of the 69 ZL1s used in organized drag racing, the model became an American drag racing icon.

The 1969 COPO Camaro ZL1 could reach 60mph in a lightning-fast 5.1 seconds while on its way to clocking 100mph in 12.4 seconds. It also took only 13 seconds to complete a quarter-mile sprint. On the other hand, the Don Yenko L72 Camaros had a blazing 5.4 seconds 0-60 mph time and could cover a quarter-mile circuit in 13.5 seconds, hitting 105 mph.

Both 427 Big-block COPO Camaros models made in '69 are scarce. The Yenko COPO Camaro production included only 201 units. As for the 1969 427 Camaro ZL1, Fred Gibbs ordered for 50 units - the least required to homologate the model for the NHRA Super Stock class. But later, other Chevrolet dealers like Nickey and Berger ordered an additional 19 ZL1 Camaros, bringing the total to 69 units.

When other dealers learned about the COPO 9561 unique code, they also placed orders for their own 427 COPO Camaros. Chevrolet eventually produced around 1,000 of them; however, many aren't as valuable as Don Yenko's and Fred Gibbs' 427 COPO Camaros.

As a result of Chevrolet's 2011 Chevrolet COPO Camaro concept attracting a great deal of interest from racing enthusiasts, Chevy revived the COPO name in 2012. Chevy has only made 69 units ever since, paying homage to the original 1969 COPO Camaro ZL1s. While getting one for most of the years required lottery luck, Chevy started selling them on a first-come first-buy basis in 2020.

Chevrolet releases limited-edition options like colors every year. It also makes special one-offs like the 2020 Chevrolet COPO Camaro John Force Edition, only sold through auction with proceeds going to charity. The automaker has added additional engine options besides a 427 cubic inch V8. Today, the COPO Camaro can be had with a gigantic 572-cubic-inch (9.4-liter) big-block V8. It's the biggest American V8 ever.

For the classic Camaro faithful and collectors, few models top the big-block 1969 COPO models. With Chevy making no more from 1970 until 2012, they are among the most desirable collector Camaros. An excellent condition 1969 Yenko Camaro, as determined by Hagerty, is worth $335,000.

The 1969 Camaro ZL1 is even more sought after by collectors. Hagerty estimates the value of a #1 condition at $1,050,000. In 2020, a 1969 COPO Camaro ZL1 (Car #59) fetched $1,094,500 at auction, setting a new record for the highest price ever paid for a Camaro.

Unlike the original 1969 Chevrolet Camaro 427 COPO, the revived versions of the COPO Camaro aren't street-legal. They cannot get licensed, registered, or driven on public roads. The original versions were street legal as they got designated Vehicle identification numbers (VINs) as opposed to the later versions, denoted by a serial number.

These Camaros are purely drag-racing specials and qualify to race in NHRA Stock and Super Stock competitions. As such, they feature a roll cage, and racing bucket seats, among many other features required for the drag strip.
