Carroll Shelby once famously said: “Horsepower sells cars; torque wins races.” We agree that torque is often a more important metric of a car’s potential and power. This is especially true for classic muscle cars with big V8 engines and massive torque figures. Today, we will look closer at the 10 most powerful cars from that period. Not horsepower but lb-ft of torque! 

1. 1970 Chevrolet Chevelle SS 454 – 500 lb-ft

The Chevelle SS was among the most popular muscle cars of the era, mainly due to its affordable price but excellent choice of engines and equipment. The 1970 model looked great, too. However, the SS454 LS6 was not only the most potent model in the lineup but also one of the quickest cars ever produced by GM. 

For just a couple of hundred dollars more over the standard 360 hp Chevelle SS 454, buyers could get the LS6 version with hotter components, a unique intake, and heads and have a 450 hp monster delivered to their dealer. However, those who got it were impressed by the performance. The Chevelle SS 454 LS6 could accelerate to 60 mph in 5.5 seconds and cover a quarter mile in just 13.2 seconds at 108 mph.

2. 1971 Buick GSX Stage 1 – 510 lb-ft

Not many people know, but Buick was a considerable force in the upper echelon of the muscle car segment. Buicks were always fast and well-equipped cars, but the quickest was the limited-production Buick GSX introduced in 1970. The GSX was a luxury muscle car with impressive firepower under the hood. The standard 455 V8 was equipped with a special intake, improved internals, and high-compression heads to deliver 360 hp. 

Of course, the factory significantly underrated the engine. However, with a massive 510 lb-ft of torque, the GSX was crowned the most powerful American car of the era. The torque was responsible for a 6.1-second 0 to 60 mph time but, even more importantly, for a 13.38-second quarter-mile time at 108 mph trap speed. 

3. 1970 Plymouth Hemi’ Cuda – 490 lb-ft

The legendary 426 Hemi engine is the most sought-after V8 of the classic muscle car scene. Everything with this monster under the hood was swift and respectable on the street, but in 1971, Hemi Cuda was on the top of the Mopar food chain. However, those who could afford 426 Hemi got an astonishing performer, a high-revving V8 with stunning good looks. 

Rated at 425 hp, realistically around 500 hp, the 1971 Hemi Cuda sprinted to 60 mph in 5 seconds flat when equipped with a close-ratio 4-speed manual. But the quarter-mile time of 13.2 seconds at 107 mph is even more impressive. If you had a Hemi Cuda in 1971, you were probably the fastest guy or girl in your area. 

4. 1970 Dodge Challenger R/T 440 Six Pack – 490 lb-ft

The Dodge Challenger R/T was a close relative of the Plymouth Hemi Cuda. However, it was without an expensive and sometimes tricky-to-maintain Hemi V8 engine. Under the hood, it had a 440 Magnum V8 with a famous Six-Pack intake (three two-barrel carburetors), which allowed this massive engine to deliver a healthy 390 hp. 

The 1970 Challenger R/T could be equipped either with an automatic or a 4-speed manual, but regardless of the transmission choice, when you hit the right pedal hard enough, you could see 60 mph in about 5.5 seconds. The quarter-mile was 13.62 seconds at 104 mph, which was enough to put this Dodge amongst the fastest cars of the era and a true classic of the muscle car genre.  

5. 1970 Plymouth Superbird 426 HEMI – 490 lb-ft

As one of the craziest muscle cars ever produced, the Plymouth Superbird was made only in 1970. Plymouth built just under 2000 road-going Superbirds to homologate the car for NASCAR racing and sold them all over America.

The car was based on the Roadrunner, and it came with a 440 V8 as standard and a 426 Hemi as the only engine option. However, Plymouth installed a nose cone, hideaway headlights, and an enormous spoiler on the back to make it as aerodynamically efficient as possible. Also, it transformed the rear glass from the standard concave-shaped one to a regular one, which proved more slippery in wind tunnel testing. 

6. 1969 Plymouth Road Runner 426 HEMI – 490 lb-ft

When it first appeared in 1968, the Plymouth Roadrunner proved to be a very influential and essential muscle car. It introduced the new trend of inexpensive and fun cars and was also a strong seller, affecting the whole segment. The entire idea behind the Roadrunner was simple. 

The most appealing thing about the Roadrunner was that Plymouth used the cartoon character of a roadrunner from the popular Willie E. Coyote cartoon. Chrysler paid $60,000 for the rights to use the name and design, and everybody thought the company was crazy for doing so. The sales results proved everybody wrong, and the Roadrunner was the first muscle car with crazy graphics and the car that started the trend. The Roadrunner had a bench seat, no luxury options, and manual steering, but it came with the powerful 383 V8 as the base engine, and buyers could also opt for the 440 or the mythical Hemi 426.

7. 1970 Ford Mustang Boss 429 – 490 lb-ft

The mythical Mustang Boss 429 is a proper muscle car legend. Ford conceived it in 1969 as a pure racing engine intended for use in NASCAR championships. The Boss 429 featured a different engine architecture than the rest of Ford’s big blocks. They made the Boss 429 much wider. 

With factory ratings of 375 HP, this unit produced over 500 HP, but it created much more in race trim. Ford decided to put this engine into the Mustang, offering a limited production of Boss 429. However, NASCAR chose not to homologate it since they only accepted intermediate and full-size cars, but the Mustang was a pony car. 

8. 1966 Dodge Coronet Hemi Sedan – 490 lb-ft

The Chrysler Corporation reintroduced its legendary 426 Hemi engine for 1966 as an option on selected Plymouth and Dodge models. The iconic powerplant was also offered as an option on Dodge Coronet, and technically, it could be ordered with any body style. However, buyers associated Hemi power with two-door coupes or convertibles, and most people didn’t realize that they could have Hemi in a sedan or even in wagon form.

That is why only a few people bought the Coronet De Luxe Hemi four-door in 1966, getting the ultimate muscle car sedan. With advertised 425 HP under your right foot, the Coronet Hemi four-door was arguably the fastest production sedan in America and the ultimate muscle car four-door. 

9. 1968 Pontiac GTO Royal Bobcat 428 – 470 lb-ft

All General Motors A-Body intermediate cars got a thorough restyling for the 1968 model year, and Pontiac debuted an all-new, sleeker, semi-fastback GTO with hideaway headlights and a special front bumper. Called the “Endura” bumper, it was GTO’s unique feature. It was basically polyurethane plastic in body color that could endure damage and hits without deforming. It was a predecessor of modern plastic bumpers. 

The 1968 Pontiac GTO Royal Bobcat 428 was a dealer-modified muscle car that pushed performance boundaries. Its 428 cubic-inch V8 engine delivered 470 lb-ft of torque and 390 horsepower. The Royal Bobcat package included performance enhancements such as recalibrated carburetors, advanced ignition timing, and improved airflow. These modifications resulted in quicker acceleration and enhanced throttle response.  

10. 1964 Pontiac GTO Tri-Power – 428 lb-ft

The Tempest GTO, as it was called, was an option on the Tempest intermediate model. For just $295, buyers would get a high-performance 396 V8 with 325 HP in standard or 348 HP in the famous Tri Power form. Manual transmission, unique trim, GTO decals, and dual exhaust were all part of the package. Since the car was light, the Tempest GTO had a pretty convincing performance, and in 1964, it was one of the quickest American cars on the market. 

Pontiac’s sales manager wasn’t particularly fond of the model but thought that the GTO package didn’t lack perspective. His estimate of a maximum of 5000 examples per year was drastically surpassed by official sales figures of over 32,000 copies. The GTO was a hit amongst the younger buyers, and the star was born.

Ford introduced the Mercury brand in 1938 and discontinued it in 2011 after 86 years of proud car-making. From the start, Mercury was positioned above Ford in terms of luxury and features but used the same mechanicals and engines. During the 1960s, the brand was very active in racing and the muscle car segment, and that is why we wanted to remind you of the 10 best muscle cars produced by Mercury. 

1. Mercury Cougar GT-E 

The 1968 Cougar GT-E was Mercury’s bold statement in the muscle car arena. Initially equipped with a 390 cubic-inch V8, mid-year saw the introduction of the 427 cubic-inch V8, delivering a factory-rated 390 horsepower. 

This made the GT-E one of the most powerful Cougars ever produced. With only 357 units built with the 427 engine, it remains a rare and sought-after collector’s item. The Cougar GT-E wasn’t just fast and good-looking but also prestigious and well-built. 

2. Mercury Cougar Eliminator 

Despite being a twin brother to the Mustang, the Mercury Cougar gained a cult following and created a name of its own in the late ’60s. But for the 1969 muscle car wars, Mercury had something special—the Cougar Eliminator. 

The Cougar Eliminator was a top-of-the-line model with several interesting engine choices. You could get a Boss 302 engine, a high-revving 5.0-liter V8 in a slightly bigger body with more luxury features. However, more buyers opted for bigger 351 or 428 Cobra Jet engines, making the Eliminator Boss 302 rare. In 1969/1970, Mercury made only 638 of those great machines in two years. 

3. Mercury Cougar XR-7 

Positioned as the luxury variant of the Cougar lineup, the XR-7 offered refined interiors with wood-grain accents, leather seating, and full instrumentation. However, it didn’t skimp on performance. The ultimate version, which perfectly combined muscle car power and luxury, was the mighty Cougar XR-7. This model had the 390 V8 engine with 320 hp, and buyers could also opt for the GT package, which included beefed suspension, stronger brakes, and steering. 

The XR-7 was a popular model, with over 27,000 produced in 1967, but only a little over 2,600 came with the GT package. Over the years, the Mercury Cougar has been in the shadow of the Mustang, but in recent years, prices have started to rise for this piece of the luxury muscle segment.

4. Mercury Cyclone Cobra Jet 

The Cyclone was introduced in 1964 and stayed on the market until 1971, but the best version, which is the most interesting to collectors, is the Cyclone CJ. Those two letters marked the presence of the famed 428 Cobra Jet engine, the first truly street-muscle engine built by Ford. With a 7.0-liter displacement and advertised 335 hp, the Cobra Jet made over 400 horsepower. The Cyclone CJ was a serious street racing contender, and this new engine significantly increased its performance. 

Along with Ford, Mercury was active in NASCAR racing during the late ’60s, and Cyclone CJ contributed to racing efforts. However, less than 3,500 Cyclones CJ were produced in 1969, while regular Cyclones without the Cobra Jet option were much more popular. 

5. Mercury Cyclone Spoiler II 

Ford had Talladega, so Mercury wanted its own Aero Special. Designers took Cyclone and copied design cues from Talladega, creating the Spoiler II model for 1969. The Cyclone Spoiler was mechanically identical; however, it was sold in two packages—Cale Yarborough Special and Dan Gurney Special. The packages had different color schemes, but otherwise were the same. The only differences between Talladega and Cyclone Spoiler II were the standard rear spoiler, front grille, and design of rear lights. 

Even though there was an official rule that the manufacturer must produce 500 or more copies of its homologation special, there was some controversy on the exact number of Cyclone Spoiler IIs produced. Official literature provides 503 examples, but experts claim that the number is much lower (around 350 cars). Rumor is that Mercury was behind with the production of the Cyclone Spoiler II. When NASCAR officials came to check the vehicles, they sneaked regular Cyclones painted in Spoiler II colors. This way, it appeared that 503 cars were produced, hiding that there are far fewer Cyclone Spoiler II made. 

6. Mercury Cougar GT 429 

The 1971 Mercury Cougar GT 429 is a rare muscle car that combines luxury and raw power. Equipped with a 429 cubic-inch Cobra Jet V8 engine producing up to 370 horsepower, it offered thrilling performance with a refined edge. As Mercury’s upscale counterpart to the Mustang, the Cougar GT featured distinctive styling, hidden headlights, and available Ram Air induction. 

The GT package added heavy-duty suspension, dual exhaust, and performance axle options. While overshadowed by more common muscle cars, the Cougar GT 429 remains a prized collector’s vehicle today, appreciated for its unique blend of elegance, brute strength, and limited production.

7. Mercury Comet Cyclone 

The Mercury Comet Cyclone, produced from 1964 to 1967, was Mercury’s bold entry into the muscle car era. Based on the compact Comet, the Cyclone offered sporty styling and performance upgrades. Early models featured 289 V8 engines, while later versions introduced larger 390 and 427 cubic-inch powerplants, delivering serious horsepower. 

With its distinctive trim, bucket seats, and rally gauges, the Cyclone combined style with speed. In 1966 and 1967, it gained a sleeker fastback design and optional performance packages. Though less celebrated than Ford’s Mustang, the Cyclone carved its niche as a potent, stylish, and underrated muscle machine of the 1960s.

8. Mercury Marauder X-100 

Mercury was well in the muscle car segment but luxury performance models were scarce, until 1969 when a new generation of the Marauder was introduced. Imagined as a luxury coupe, the Marauder had a fresh design with interesting features like concealed headlights, a massive front end, and a sloping rear end with concave rear glass. It was a big, heavy car for cruising rather than street racing. 

Behind the strange name was a regular 1969 Marauder with a 429 V8 engine producing 360 hp, bucket seats, heavy-duty suspension, blackout rear trim, and fender skirts. The performance was respectable, but it was still a big and heavy car, so it was significantly slower compared to some bare-bones, smaller, and lighter muscle models. 

9. Mercury Capri RS

The introduction of the third-generation Mustang had a significant influence on Mercury, too, since the brand got its version in the form of the Capri in 1979. From 1970 to 1977, Mercury sold the Capri, which was an imported model from Germany with four—and six-cylinder engines, but in 1979, thanks to the Mustang, the Capri was brand new and featured a unique front-end design. 

Mercury introduced the RS model as the performance version, which featured a 2.3-liter turbocharged engine with a whopping 135 hp. The performance was expectedly bad, but the car looked cool with a big air intake on the hood, big RS badges, and a rear spoiler. Today, those RS models are quite rare, although not very valuable or sought-after by collectors. 

10. Mercury Marauder 

Even though Ford never intended the Grand Marquis to be a performance car, Mercury decided to turn it into one. They installed a highly tuned 4.6-liter V8 with 302 HP and a revised suspension, gearbox and brakes. These changes turned this sleepy, comfy sedan into a sharp muscle car. It came in three colors, but the black Marauder had menacing looks and an aggressive stance, differentiating it from its sedate cousins.

The performance was impressive for a big, heavy sedan. It could go from 0 to 60 mph in around seven seconds. However, the most significant asset was its appearance. Seeing this big, black sedan in a rearview mirror could make drivers want to pull over to the side of the road.

Oldsmobile wasn’t always the dusty nameplate that faded quietly into history. Back in its prime, it was one of GM’s boldest divisions—often used to test wild ideas, futuristic tech, and luxury features that would later trickle down to the rest of the lineup. From sleek gullwing coupes to hybrid prototypes and digital dashboards before anyone else had them, Oldsmobile concept cars showed what the future might look like… even if most never made it to production. Here are 10 Oldsmobile concepts that prove this brand once had its eyes on the future.

1985 Oldsmobile Incas

Looking like something out of Blade Runner, the Incas was a futuristic gullwing sports coupe with an insane cockpit. It had a yoke-style steering wheel, digital dash, and wraparound glass canopy. Powered by a mid-mounted turbocharged 4-cylinder, the Incas was never meant for production—but it turned heads worldwide.

It was built by Italdesign and packed with tech that felt like sci-fi in the ’80s. Oldsmobile was trying to rebrand itself as a high-tech innovator, and the Incas was a bold, memorable start. Most people forget that Oldsmobile was te pinnacle of technology at one point in time.

Honda has a reputation for reliability and smart engineering—but its design lab has also produced some downright bizarre ideas. Over the years, the brand has rolled out concept cars that teased futuristic tech, wild styling, or clever packaging. Some looked ready for production… but fizzled out. Others were just too strange to ever see the light of day. Whether due to bad timing, market shifts, or just being too far ahead of the curve, these 10 Honda concept cars failed to make it to showrooms—leaving behind only what-ifs and display stand memories.

2003 Honda Kiwami

The Kiwami looked like a rolling piece of origami. With its sharp edges, ultra-clean design, and hydrogen fuel cell powertrain, it was Honda’s vision of an elegant, high-tech luxury sedan. Inside, it was pure Zen—open space, wood floors, and a minimalist dash.

2003 Honda Kiwami

But hydrogen tech was still a long way from viable, and the styling was far too radical. The Kiwami vanished after the auto show circuit, leaving behind a cool name and a reminder that sometimes elegance just isn’t enough to go mainstream.

1993 Honda EVX

Before Tesla was even a dream, Honda was experimenting with electric sedans. The EVX had an ultra-aerodynamic body and a fully electric drivetrain—long before anyone took EVs seriously. It featured solar panels on the roof, regenerative braking, and a digital cockpit.

1993 Honda EVX

Unfortunately, the battery tech just wasn’t there in the early ’90s, and Honda quietly shelved the project. While it was a clear look into the future, the world wasn’t ready—and neither was Honda’s supply chain. Honda was pushing the envelope of design around this time period.

2008 Honda FC Sport

A hydrogen-powered sports car? That’s what the FC Sport was aiming for. With a futuristic three-seat layout (driver in the middle) and super-low body lines, it looked like something out of Tron. Honda never planned to produce it, but it turned heads at auto shows and made a big splash in design circles.

2008 Honda FC Sport

Still, no one was asking for a hydrogen NSX. The FC Sport never evolved past the concept phase, but it was a cool reminder that Honda wasn’t afraid to dream weird. The sleek body was ahead of it’s time and this is still one of the most beautiful concept cars to come out of Japan.

1995 Honda SSM (Sports Study Model)

This sleek roadster looked ready to be the next big thing—and eventually evolved into the S2000. But the SSM itself was never sold. With its long hood, rear-wheel drive layout, and clean lines, it previewed what enthusiasts wanted from Honda.

1995 Honda SSM (Sports Study Model)

However, delays in development, market caution, and internal hesitation meant the SSM was shelved in favor of a more refined product later on. The SSM wasn’t a total failure—but it never reached customers, even though it probably should have.

2001 Honda Unibox

Imagine a translucent plastic minivan with wheels at the corners and a lounge-style interior—and you’ve got the Unibox. Designed as a next-gen city vehicle, it focused on interior space and modular design. The floor had rails to move seats around, and everything inside felt more like Ikea than Detroit.

2001 Honda Unibox

The Unibox was quirky and imaginative, but Honda knew there was no way it would sell in real life. Still, parts of it—like reconfigurable seats—live on in Honda’s more practical minivans and SUVs. This was one of the most unique Honda concepts to come out of the new decade.

1999 Honda Fuya-Jo

This was Honda’s party car. Seriously. The Fuya-Jo was a Tokyo Motor Show concept aimed at night clubbers. It featured a tall roof so you could stand inside, DJ-style controls, and joystick steering. This was a purple beast of a concept car that didn’t look like anything else on the road.

1999 Honda Fuya-Jo

Meant to be driven short distances between clubs, it was more like a rolling rave box than a real car. Unsurprisingly, it went nowhere. But it still earns a spot on this list for being one of Honda’s most unexpected and bizarre creations ever.

2006 Honda REMIX

A small, two-seat coupe that looked ready to take on the Mazda MX-5? That was the REMIX. Lightweight, sporty, and affordable-looking, it had real potential. Car fans loved the shape and simplicity, but Honda said no—fearing it wouldn’t sell well enough.

2006 Honda REMIX

The REMIX could’ve been the spiritual successor to the CR-X, but instead it faded into concept car limbo. It’s one of those cases where the enthusiast world said “yes” and the corporate side said “nah.”

2007 Honda Puyo

The Puyo looked like a marshmallow on wheels. Built to promote hydrogen fuel cell tech and soft, people-friendly design, the car literally had a gel-like outer shell designed to reduce injury in low-speed crashes. It also glowed at night and had a joystick instead of a steering wheel.

2007 Honda Puyo

While cute and creative, the Puyo was far from production-ready. Still, it showed Honda’s weird and wild side—and its commitment to safety and alternative fuels, even in jellybean form. Honda has built quite a few.

1992 Honda EP-X

Another electric experiment from the early ’90s, the EP-X was a sleek, two-seat EV concept with a focus on lightweight design and city driving. It looked like a cross between a CRX and a spaceship. Honda never released full specs, but the car was rumored to have limited range and very basic interior features.

1992 Honda EP-X

At the time, there just wasn’t a real market for small electric cars—and Honda wasn’t ready to commit. So the EP-X quietly disappeared after a few show appearances. The Honda EP-X was a unique concept car that managed to spark a lot of interest in a Honda sports car.

2000 Honda Spocket

Half roadster, half pickup, the Spocket was one of Honda’s strangest “what if” ideas. The front was a stylish two-seater roadster, while the back had a tiny truck bed for hauling gear. It had a hybrid powertrain and was aimed at adventurous city dwellers who needed both style and utility.

2000 Honda Spocket

As odd as it was, the Spocket got people talking. Still, it was way too niche for mass production, and Honda shelved it right after its auto show run. If a Ridgeline and an S2000 had a baby, this would be it. The Spocket also became a fairly famous Hot Wheel toy as well.

Most popular classic muscle cars have been sold in tens of thousands (or more) of examples. This means that those models can be found for sale easily. However, in the muscle car heyday, Detroit presented several pretty rare models, and none of them exceeded production figures of 1000 copies. If you wonder what those cars are, here is the answer. 

1. Buick GSX

Backed by steady sales and outstanding reception of their muscle models, Buick decided to introduce the ultimate muscle car: the legendary and scarce Buick GSX. The GSX stood for Gran Sports Experimental and was, in fact, the visually upgraded Gran Sport with a Stage 1 performance package. 

The GSX debuted in 1970 with an aggressive graphics package that was not typical of Buick products. It was available in two bright colors—Saturn Yellow and Apollo White—with front and rear spoilers, functioning hood scoops, side stripes, and Rally wheels. Buick produced only 678 examples that year. 

2. Pontiac Firebird Trans Am

The Trans Am model became popular and mass-produced in later generations, but in 1969, it was a rare and special limited edition car. In 1969, Pontiac wanted to present a model that could be homologated for Trans Am racing, but the company was under a racing ban from GM. To mask its intentions, Pontiac introduced the Firebird Trans Am as a loaded version that featured considerable block power from the famous 400 V8 engine equipped with a Ram Air III or IV intake system. 

The difference between those engines was significant since Ram Air IV featured many improved engine internals and components, but they were both rated at 366 hp, which was pretty underrated. However, this special version with signature white paint, blue stripes, Rally II wheels, and other equipment proved to be a tough seller, and only 634 Firebird Trans Ams were sold. Among those, only 8 were convertibles.

3. Mercury Cougar Eliminator Boss 302

Despite being a twin brother to the Mustang, the Mercury Cougar gained a cult following and created a name of its own in the late ’60s. But for the 1969 muscle car wars, Mercury had something special—the Cougar Eliminator. 

The Cougar Eliminator was a top-of-the-line model with several interesting engine choices. You could get a Boss 302 engine, a high-revving 5.0-liter V8 in a slightly bigger body with more luxury features. However, more buyers opted for bigger 351 or 428 Cobra Jet engines, making the Eliminator Boss 302 rare. In 1969/1970, Mercury made only 638 of those great machines in two years. 

4. Ford Torino Talladega

In contrast to some models from our list, which were produced for 12 months or so, Torino Talladega was made for only a couple of weeks in early 1969. This car was Ford’s answer to Dodge Daytona and Mopar’s efforts to win in NASCAR. 

The idea behind the Talladega (named after the NASCAR track) was to take a standard Torino, give it a unique front end and a few slippery details, and homologate it for superspeedways. A total of 754 Talladega were built in such a short time, and many of them were used for racing.

5. Chrysler 300 Hurst

Introduced in 1970, the special limited edition 300 Hurst was a special model based on the new full-size Chrysler platform. It was built in minimal numbers, around 500, with the help of the famous transmission company Hurst. 

It featured an exceptional white and gold paint job, a similarly styled interior, and a rear spoiler integrated into the rear deck lid. Under the hood, a mighty 440 V8 engine with 395 hp could propel the 2-ton beast to respectable acceleration times. 

6. Dodge Charger 500

Most muscle car fans know the Dodge Charger lineup well, including the wild Charger Daytona from 1969. But Daytona’s predecessor, the Charger 500, was far less known and less successful. The standard Charger, with a deep grille and concave rear glass, wasn’t very aerodynamic, and despite powerful engines and good drivers, it just couldn’t achieve the speeds required for winning. 

Dodge decided to introduce a limited-edition Charger 500 (named 500 because it was produced in that many examples) with a flush grille, fixed headlights, and regular rear glass to improve the car’s aerodynamics. The Charger 500 had two engines, a standard 440 and an optional 426 Hemi. Since the Daytona was much more successful and interesting, the Charger 500 was soon forgotten by all except for hardcore Mopar muscle guys.

7. Chevrolet Chevelle Z16

What exactly is the Chevelle Z16? Basically, it’s a fully loaded regular Chevelle with all go-fast options, a 396 V8 engine with a Muncie 4-speed gearbox, and heavy-duty suspension and equipment. 

Some dealers weren’t even aware that this option existed, and Chevrolet refused to market the Z16 for some reason, making this Chevelle kind of a secret model.The Z16 was fast, but it was also expensive for a Chevrolet. That is why they made only 200 of them. 

8. Dodge Charger Daytona

In the late ’60s, Dodge was desperate to enter NASCAR racing, and the Charger was the perfect candidate. However, since NASCAR cars already approached high speeds of almost 200 mph on newly constructed superspeedway tracks, aerodynamics played a key role in a car’s performance and results. 

So Dodge decided to go all out and create a racing car with a special front end, flush rear glass, and a prominent rear spoiler. The Charger Daytona was one of the first cars to be developed in a wind tunnel, and new materials were used in its construction. It was a one-year-only model, and 504 were produced.

9. Plymouth Barracuda Hemi

Two of the biggest Chrysler legends from the classic days of muscle car culture are the Barracuda and the 426 Hemi engine. All through the ’60s, those industry icons didn’t mix, at least not in street-legal cars. In 1970, Plymouth offered this legendary engine in the Barracuda body style, immediately creating one of the fastest and most desirable muscle cars ever made. 

The mighty Hemi engine was an expensive top-of-the-line option for 1970 and 1971, available in coupe or convertible form. It cost around $900 more than the standard Barracuda, and it was installed in just about 600 coupes and only 17 convertibles during a two-year production period. The power was rated at 425 HP, but everybody knew that the orange monster delivered more than 500 HP straight from the box. 

10. Chevrolet Camaro ZL-1

The Camaro ZL-1 was the same as the regular 1969 Camaro on the outside, but it was so fast it was barely street-legal. The official 1969 Chevrolet literature doesn’t mention the ZL-1 option for the Camaro, but if you were a successful drag racer or a dealer, you knew about this expensive option. That is why only 69 Camaros ZL-1 left the factory. 

The secret of the Camaro ZL-1 was its engine. It was a high-revving 7.0-liter V8 with around 550 hp in mild tune. Chevrolet produced about 200 of those engines, and while most of them went to Can-Am racing teams, 69 ZL-1 engines were installed in C.O.P.O Camaros and sold to drag racing teams.
