Muscle cars were huge in the 1970s. This era was coming to a close by the time the decade ended, but that didn’t stop Chevrolet from producing some incredible muscle cars that many drivers loved and enjoyed. When it comes to rare and unusual cars, these ten Chevy models take the cake. 1977 Chevrolet Camaro Z/28 Number Produced: 13,000 Chevrolet This car was one of the best-looking muscle cars of the era, making a bold comeback after being discontinued in 1974. The 1977 Chevrolet Camaro Z/28 screamed muscle and performance from every angle, making it one of the most admirable cars of the decade. The decals and badges ensured everyone knew what it was.The F-Body design of the Camaro Z/28 gave it a long, low, and wide appearance, making it easy to admire while it drives. This Camaro had a dual-exhaust system to give it the deep muscle car growl, and it could be had with positraction to help keep it under control when pushed hard. This car signaled the return of the top Camaro name. 1970 Chevrolet Camaro SS Number Produced: 12,476 Hagerty The 1970s Chevrolet Camaro SS was a bit of a confusing model. Although the numbers look impressive, the SS would only make up about one-tenth of the total Camaro models produced that year. The SS was originally listed with the 454 cu-in big block V8 offered, but that was a typo, as none with that configuration were ever produced.The Camaro SS was actually the more powerful version of the car than the venerable Z/28, which produced 360 horsepower from its engine. These confusions might be why the 1970 Camaro SS wasn’t one of the most popular versions ever made, but that rarity allows this car to be a fantastic muscle car with a great story. 1975 Chevrolet Laguna S-3 Number Produced: 7,100 Classic Car Restoration Club The 1975 Chevrolet Laguna S-3 was a take on the Chevelle that was only available in two-door coupe versions. The semi-fastback style was enhanced with body stripes to give this car the low and sporty look desired. The louvered rear quarter windows were a signature feature of the Laguna S-3, which also came with Rally wheels to give it an excellent look.The Laguna S-3 was made for three years, but the 1975 version added a little more sizzling style with a slanted aerodynamic nose, which made it look cool and allowed this car to be a top performer in NASCAR. Several drivers won races in the Laguna, with Cale Yarborough taking the checkered flag 33 times in this car. 1971 Chevrolet El Camino SS 454 LS6 Number Produced: 4,543 Chevrolet One of the most interesting vehicles in history is a muscle car with a pickup bed. The 1971 Chevrolet El Camino SS 454 LS6 was a high-powered beast that could carry a heavy load in the bed or pull a trailer, but was also capable of rocketing to high speeds in a hurry. The front half was identical to the Chevelle, but the rear was fitted with a truck bed in a unibody style.Some would say the El Camino doesn’t deserve to be considered a muscle car, but with impressive performance figures and a low stance, it’s hard to leave it out of the conversation. The lightweight nature of the vehicle makes it one of the fastest GM cars of the 1970s, which is certainly worthy of consideration. 1970 Chevrolet Chevelle SS 454 LS6 Number Produced: 4,475 American Muscle Car Museum During the Golden Age of American Muscle, the Chevrolet Chevelle was one of the most iconic cars. The 1970 Chevrolet Chevelle SS 454 LS6 was one of the rarest models of this car, but it was easily the pinnacle of design and performance among American muscle cars. The design changes added in 1968 created a car that looked like a battering ram by 1970. If you want true rarity in the Chevelle, only 20 of these cars were convertibles, but that is simply an additional body style of the big-block Chevy muscle car.The Chevelle is all attitude and zero apologies, making it one of the most iconic muscle cars of the era. Most models are equipped with smaller engines, but a special few have the massive LS6 engine, which meant more power, more speed, and much more aggression on the road and on the track. 1970 Chevrolet Monte Carlo SS Number Produced: 3,823 Chevrolet Typically, the Monte Carlo isn’t thought of as a rare muscle car, but the SS model from 1970 was one of those cars that was only built in a few versions. The powerful V8 engine and two-door midsize car build gave the Chevrolet muscle cars a classic look, coming out of the 1960s and going into the 1970s.The Monte Carlo was considered a bit of an upscale car compared to other Chevy cars of the time. That said, it was still a legitimate street machine that could take on other challengers and leave them far behind. It was a street predator waiting to pounce on its next prey. 1972 Chevrolet Corvette Stingray LT-1 Number Produced: 1,741 Hagerty One of the most stunning and exciting Chevrolet cars of the 1970s is the 1972 Chevrolet Corvette Stingray LT-1. The LT-1 engine made the car rare, and it was the final year that the Corvette had chrome bumpers, which gave the car a sleek and stylish look. This car is easily recognizable wherever it goes.This Corvette featured signature pop-up headlights, which allowed the front to come down at a sharp point, making the car a show-stopper wherever it goes. The cabin was also impressive, featuring a driver-focused cockpit that ensured every drive could feel like a race if that’s what drivers were looking for. 1970 Chevrolet COPO LT-1 Nova Number Produced: 177 Audrain Auto Museum The 1970 Chevrolet COPO LT-1 Nova was almost the rarest muscle car from the brand during the 1970s. Don Yenko was famous for using the special order system of Chevrolet (COPO), to buy and sell souped-up muscle cars during the late 1960s and early 1970s. The most famous Yenko car is the Camaro, but the Nova received similar treatments with the LT-1 engine.In addition to the powertrain upgrades, the Yenko team added an upgraded suspension system, new sway bars, and a limited-slip differential. Once the COPO Nova models reached his dealership, he swapped the wheels and added a hood-mounted tach and Yenko decals to the mix, giving drivers special cars that were fun to drive. 1972 Chevrolet Corvette ZR1 Number Produced: 20 Mecum The 1972 Chevrolet Corvette ZR1 was the final year of an early three-year run for this car. During the three years from 1970-1972, only 53 units of this car were made and 20 of those were produced for the 1972 model year. Drivers who opted for this high-performance Corvette sacrifice key comfort and convenience items in the name of performance.The Corvette ZR1 was meant to be the counterpart to the LT1, giving drivers a great car for amateur road racing, which made this car great on the track, but not as comfortable on the road. Instead of air conditioning and power steering, drivers got a cold-air hood, a larger radiator with a different shroud and fan, the Muncie "rock crusher" transmission, electronic ignition, and handling improvements to make it possible to take the checkered flag in local races. 1971 Chevrolet Corvette ZR2 Number Produced: 12 Hagerty The rarest Chevrolet Muscle Car of the 1970s was the 1971 Chevrolet Corvette ZR2. This car was so rare that only 12 were produced, two of which were convertible models. This car came along to mark the end of the era before automakers began using lower compression ratios to meet the new emissions regulations of the decade.The ZR2 model was essentially one last hurrah for the 454 LS6 engine, giving this Corvette 425 horsepower and several high-performance options. The ZR2 was the ultimate Corvette, and it was only offered for one model year. The chassis and cooling upgraders were what made this car the ZR2 and differentiated it from other Corvette models. In today’s market, this car can fetch nearly $450,000 at auction due to its rarity.
