30: 1969 Dodge Dart GTS 440
What happens when you cram a massive 7.2-liter (440 cubic inch) V8 engine into a relatively compact mid-size coupe? Compromises. In the case of the 1969 Dodge Dart GTS 440, essentials like a brake booster and power steering had to be omitted to make room for the big-block powerhouse. Considering this potent Dart could demolish a quarter-mile in roughly 14 seconds, bringing it to a halt with its standard drum brakes was reportedly a white-knuckle experience. Drivers described harrowing moments of the car hopping sideways and shaking violently under hard braking, all while wrestling with the unassisted, heavy steering. But for enthusiasts of raw classic American muscle, isn’t a little drama part of the high-speed thrill?
29: 2017 Pontiac Trans Am Super Duty
2017 Pontiac Trans Am Super Duty roaring with modern performance
Technically, this fire-breather starts life as a Chevrolet Camaro SS before undergoing a radical transformation by the artisans at Florida’s Trans Am Worldwide. It receives bespoke front and rear fascias, iconic glass T-tops, and, naturally, a functional hood scoop crowned by the legendary “screaming chicken” decal. Beneath that feathered emblem, however, lies pure, unadulterated muscle. A potent LSX V8 is installed, force-fed by a Whipple supercharger, and exhaling through custom headers and exhaust, all channeled through a robust six-speed Hurst transmission. The result? A staggering 1,000 horsepower. Builders noted difficulty keeping it strapped down on the dyno, estimating over 700 lb-ft of torque hitting the rear tires. This modern interpretation of a classic American muscle legend comes with a price tag exceeding $150,000, not including the original donor Camaro.
28: 1968 Mercury Cyclone GT
The 1968 model year brought a significant and stylish transformation for the Mercury Cyclone. The previous boxy, Fairlane-based body was replaced with sleek, swooping lines borrowed from the contemporary Ford Torino, giving it a much more aggressive and appealing look. While the standard engine in the Cyclone GT trim was technically downgraded from a 390 V8 to a 302 V8, buyers had the crucial option to specify the formidable 427 V8. This powerhouse delivered a potent 390 horsepower, turning the stylish coupe into a serious performance machine. Among the Cyclone GTs, the convertibles equipped with the optional four-speed manual transmission are the rarest and most desirable, representing a sought-after piece of classic American muscle history.
27: 1966 Chevy Biscayne
Sleeper 1966 Chevy Biscayne L72 hiding its potent V8 power
Don’t underestimate Chevrolet’s entry-level full-size offering from 1966; the Biscayne could be ordered as a surprisingly formidable performance car. By eschewing luxury features like power seats, power windows, and opting for more basic carpeting and upholstery, the Biscayne shed valuable weight compared to its more opulent siblings like the Impala. Crucially, Chevrolet offered incredible performance options, including the legendary 427 cubic inch L72 V8. Selecting this engine automatically upgraded the suspension with heavier-duty springs, shock absorbers, and sway bars. An even more capable F41 suspension package added a thicker front sway bar and introduced one at the rear for improved handling. With no external tells like hood scoops or special badging, these “sleeper” Biscaynes packed a hidden punch, often leaving unsuspecting rivals bewildered in their dust – a true wolf in sheep’s clothing from the classic American muscle era.
26: 1964 Dodge Polara 500
1964 Dodge Polara 500, a drag strip dominator with space-age naming
Named with a nod to the Polaris star to capitalize on the excitement surrounding the era’s space race, the Dodge Polara succeeded the Coronet and quickly established itself as a force on the drag strips. The 1964 models were particularly potent weapons. Buyers could equip their Polara 500 with the powerful Ramcharger 426 Wedge engine, officially rated at 415 horsepower, or opt for the legendary 426 Hemi, conservatively listed at 425 horsepower but known to produce closer to 550 ponies in reality. When properly tuned for drag racing, these classic American muscle machines were capable of blistering quarter-mile times, running the distance in the low 12-second range at speeds approaching 120 mph, making them dominant competitors in their day.
25: 1966 Oldsmobile Toronado—Jay Leno Edition
A standard 1966 Oldsmobile Toronado was already impressive, featuring a 7.0-liter V8 producing a healthy 385 horsepower. However, standard wasn’t enough for renowned car enthusiast Jay Leno. He transformed his Toronado into an automotive beast, fitting it with a heavily modified, twin-turbocharged, aluminum 425 cubic-inch LS6 V8 engine that unleashes an incredible 1,070 horsepower. While the exterior largely retains its stock classic American muscle appearance, beneath the surface, it rides on a significantly reworked C5 Corvette chassis and suspension system. Furthermore, while the original Toronado was a pioneering front-wheel-drive car, Leno wisely converted his creation to rear-wheel drive to handle the monstrous power output, creating a unique and incredibly potent custom build.
24: 1967 Mercury Cougar GT
1967 Mercury Cougar GT showcasing its hidden headlamps and V8 power
The Mercury Cougar represents the most successful vehicle launch in the brand’s history, with an impressive 150,000 units built during its debut year, 1967. Among this production run, approximately 12,000 were elevated to the performance-oriented GT trim level. Concealed behind the Cougar’s distinctive rotating headlamps resided a potent 390 cubic-inch Marauder GT V8 engine, generating a respectable 320 horsepower. The GT package wasn’t just about power; it also included crucial upgrades like enhanced suspension components, larger brakes, wider wheels and tires, and a less restrictive exhaust system. These modifications ensured that the Cougar GT could effectively translate its V8 muscle to the road, making it a sophisticated and capable entry in the classic American muscle car segment.
23: 1969.5 Dodge Coronet Super Bee A12
Introduced mid-way through the 1969 model year (hence the “.5” designation), the Dodge Coronet Super Bee A12 was a mid-sized muscle offering strategically aimed at budget-conscious buyers seeking serious Mopar performance. Its heart was a potent 390 horsepower V8 engine featuring a then-novel induction setup: three two-barrel carburetors, famously known as the “Six Pack.” Dodge engineers didn’t stop there; they meticulously tweaked various engine and suspension components to maximize power and straight-line speed. The “Bee” in its name is widely believed to reference the car’s “B-body” platform, while the “Super” prefix requires little explanation given the formidable powertrain. The A12 package delivered raw, accessible classic American muscle performance.
22: 1970 Ford Mustang Boss 429
Iconic 1970 Ford Mustang Boss 429, a rare homologation special
In 1970, acquiring a Ford Mustang Boss 429 required a significant investment of $4,087 (approximately $33,000 in today’s currency). This special Mustang housed a unique semi-hemispherical head 429 cubic-inch V8, officially rated at 375 horsepower, designed primarily to homologate the engine for NASCAR competition. The Boss 429 could sprint through the quarter-mile in a solid 14.0 seconds and achieve a top speed nearing 120 mph. Its production was limited to just two years, 1969 and 1970, with fewer than 1,400 examples ever rolling off the assembly line. This rarity, combined with its unique engine and racing pedigree, makes the Boss 429 one of the most collectible and revered classic American muscle cars.
21: 1970 Oldsmobile 442 W-30 Convertible
Seeking to challenge the dominance of Pontiac’s GTO, Oldsmobile developed the potent 442 package, initially derived from the heavy-duty “police apprehender” version of its popular Cutlass model. This muscular beauty boasted the defining “4-4-2” configuration: a four-barrel carburetor, a four-speed manual transmission, and dual exhausts (though the definition evolved over time). Power came from a massive 455 cubic-inch V8 churning out 370 horsepower. Opting for the W-30 package added further performance enhancements, including functional fiberglass hood scoops feeding cold air to the engine, an aluminum intake manifold for lighter weight, and a more aggressive camshaft profile. While Oldsmobile built 3,100 examples of the 442 W-30 in 1970, only a mere 264 were produced in the highly desirable convertible body style, making it a rare and valuable piece of classic American muscle.
20: 1973 Pontiac Firebird Trans Am SD-455
1973 Pontiac Firebird Trans Am SD-455, the pinnacle of Pontiac performance
The heart of the 1973 Pontiac Firebird Trans Am SD-455 was the legendary Super Duty (SD) 455 engine. While the 455 displacement wasn’t new, the SD version featured significant internal modifications designed for durability and high performance, standing out during the early days of emission controls. Key upgrades included a strengthened cylinder block incorporating four-bolt main bearing caps for increased rigidity under stress. This meticulously engineered engine quickly earned the SD-455 Trans Am a reputation as arguably the fastest Pontiac ever produced in stock form. Officially rated lower due to insurance and regulatory pressures, the engine produced well over 300 net horsepower, but tuners found much more potential. With modifications like an optimized intake manifold, a wilder camshaft, and free-flowing headers, the SD-455 could generate upwards of 600 horsepower and 600 lb-ft of torque, cementing its status as a late-era classic American muscle icon.
19: 1987 Buick GNX
Produced for just one year as an evolution of the already formidable Grand National, the Buick GNX (Grand National Experimental) stunned the automotive world. At the time of its release, it was hailed as the fastest production car built in America. Its turbocharged 3.8-liter V6 engine was officially rated by Buick at 276 horsepower and 360 lb-ft of torque. However, independent dynamometer testing revealed the true figures were closer to 300 horsepower and a massive 400+ lb-ft of torque. This underrated powerhouse enabled the menacing, all-black GNX to launch from 0 to 60 mph in a blistering 4.7 seconds – quicker than contemporary rivals like the Lamborghini Countach and Chevrolet Corvette. This impressive performance wasn’t solely Buick’s doing; they collaborated with McLaren Performance Technologies/ASC to fine-tune the engine and suspension, creating a sophisticated and brutally fast final statement for classic American muscle in the 1980s.
18: 1971 Plymouth GTX
Sleek 1971 Plymouth GTX, a rare Hemi-powered muscle car
With Pontiac having claimed the GTO moniker, Plymouth designated its top-tier muscle machine the GTX, standing for “Grand Touring Extra.” Based on the redesigned B-body platform for 1971, the GTX featured sleek “fuselage” styling. Production numbers for the ’71 GTX were relatively low, with fewer than 3,000 units built in total. Today, well-restored examples command prices reaching $150,000 or more. The true unicorns among them are the Hemi-powered GTXs. Only 30 cars were equipped with the legendary 426 cubic-inch Hemi V8, boasting 425 horsepower and a tire-shredding 490 lb-ft of torque. This combination of sophisticated styling and earth-moving power makes the 1971 Hemi GTX an exceptionally rare and desirable example of classic American muscle.
17: 1970 Ford Torino King Cobra
In a bid to dethrone Dodge and Plymouth from their NASCAR dominance achieved with the Charger Daytona and Road Runner Superbird, Ford initiated a project to develop an aerodynamically superior competitor based on the Torino coupe. A specialized team of engineers crafted a distinctive aero package, featuring a smoothly integrated, sloped front end designed to replace a simple nose cone, along with a larger grille opening positioned lower to the ground for improved airflow at high speeds. However, a critical omission proved fatal: the lack of a large rear spoiler, like those found on its Mopar rivals. This resulted in aerodynamic instability, particularly in high-speed corners, where the car’s rear end tended to lift unpredictably, making it difficult and dangerous to drive near its 200 mph target speed. Rather than invest further in development to rectify the issue, Ford ultimately canceled the King Cobra project. Only three prototypes were ever produced, making this ambitious but flawed classic American muscle aero warrior exceedingly rare.
16: 1970 Buick GSX
Bold 1970 Buick GSX in Saturn Yellow, known for massive torque
Instantly recognizable in its signature Saturn Yellow or Apollo White paint schemes with bold black striping, the 1970 Buick GSX was a visually striking machine with the performance to back up its looks. It served as Buick’s ultimate expression of classic American muscle. The standard engine for the GSX was a massive 455 cubic-inch V8, conservatively rated at 350 horsepower but producing an astonishing 510 lb-ft of torque. At the time, this torque figure was the highest offered in any American production muscle car, giving the GSX incredible off-the-line acceleration. For even greater performance, Buick offered the GSX Stage 1 package. Only 479 examples of this up-tuned variant were built, featuring enhancements for even more power. Today, genuine GSX Stage 1 models are highly sought after by collectors, often commanding prices exceeding $120,000.
15: 1966 Ford Galaxie 500
The Ford Galaxie 500 occupied a unique position in the mid-1960s, serving as both a popular full-size family sedan and a formidable competitor on NASCAR ovals and drag strips. While several model years offered performance potential, 1966 stands out as a particularly desirable year. This was when Ford introduced the potent new 7.0-liter (428 cubic inch) Thunderbird V8 engine option for the Galaxie line. For those seeking the ultimate sleeper performance, the rare “Police Interceptor” version is the one to find. These models featured an uprated version of the 428 engine, tuned to produce 360 horsepower, combined with heavy-duty suspension and brakes, making this unassuming sedan a surprising contender in the classic American muscle landscape.
14: 1964 Ford Fairlane Thunderbolt
1964 Ford Fairlane Thunderbolt, a lightweight factory drag racer
The Ford Fairlane Thunderbolt was a purpose-built, homologation special created specifically for drag racing dominance. Ford produced only 100 units, the minimum required to qualify for competition in the NHRA Super Stock class – a class it promptly dominated, securing the championship title in its debut year. This was a true factory skunkworks project, transforming the modest Fairlane into a lightweight terror. Power came from Ford’s mighty 7.0-liter (427 cubic inch) V8, officially rated at 425 horsepower. However, like many engines of the era, this figure was notoriously underrated for classification purposes; actual output was closer to 500 horsepower. Stripped of non-essentials and featuring fiberglass body panels and Plexiglas windows, the Thunderbolt was essentially a race car barely disguised for street use. It could rocket from zero to 60 mph in an astonishing 4.7 seconds and run the quarter-mile in under 12 seconds, making it one of the most extreme examples of classic American muscle ever offered by a major manufacturer.
13: 1963 Pontiac Catalina
During the early 1960s, specially prepared, lightweight versions of the Pontiac Catalina, drawing heavily on NASCAR technology, were dominant forces on drag strips across America. This full-size two-door sports sedan packed serious punch, particularly when equipped with the available 421 cubic-inch H.O. (High Output) V8 engine, rated at 370 horsepower. The 1963 model year Catalinas are especially prized by collectors for the ultra-rare Super Duty (SD) trim. These cars were already built using lightweight aluminum components, but some examples went even further, featuring frames drilled with numerous holes – the infamous “Swiss cheese” frames – to shed every possible pound. This obsessive focus on weight reduction resulted in an incredible power-to-weight ratio. Unfortunately, GM implemented a corporate ban on factory-backed racing later that year, bringing the official Super Duty program to an abrupt end. Nevertheless, the 1963 Catalina Super Duty remains a legendary contender in the annals of classic American muscle.
12: 1970 Chevrolet Chevelle SS Convertible
1970 Chevrolet Chevelle SS Convertible, a popular and powerful drop-top muscle car
The Chevrolet Chevelle Super Sport (SS) was arguably one of the most popular and iconic muscle cars of its era, and the 1970 model is often considered the pinnacle. Demand was enormous, with over 51,455 Chevelle SS models rolling off General Motors assembly lines that year. However, the convertible version was significantly rarer, with only around 1,100 drop-top SS units produced. Today, these open-air Chevelles in good condition command prices upwards of $70,000. Buyers seeking potent performance could opt for engine choices like the RPO L34, a 396 cubic-inch big-block V8 generating a healthy 350 horsepower and 410 lb-ft of torque, or the legendary LS6 454 V8. The combination of stunning looks, big-block power, and open-air motoring makes the 1970 Chevelle SS Convertible a highly desirable classic American muscle car.
11: 1969 Pontiac GTO Judge Convertible
While the standard Pontiac GTO was already a groundbreaking powerhouse and a visual stunner that arguably kickstarted the muscle car craze, the optional “Judge” package introduced in 1969 added extra flair and exclusivity. Judge models featured unique tri-color side stripes, a blacked-out grille (deleting the standard chrome), and a distinctive pedestal-mounted rear spoiler painted to match the body color. These visual cues signaled that this GTO was something special. Under the hood, the Judge came standard with the potent Ram Air III version of Pontiac’s 400 cubic-inch V8, delivering 366 horsepower thanks to functional hood scoops feeding cool air to the engine. By 1969, the popularity of convertibles had begun to decline, resulting in very limited production numbers for the GTO Judge drop-top. Only around 150 examples were built, making it the rarest and most sought-after variant of this iconic classic American muscle trim.
10: 1970 Plymouth Road Runner Superbird
1970 Plymouth Road Runner Superbird with its iconic massive rear wing
If you crave a head-turning classic American muscle car from the 1970s capable of hitting 60 mph in under five seconds – an absolutely ludicrous time for the era – and equipped with a horn that playfully mimics the famous “Meep Meep” of the Looney Tunes Road Runner character, then the 1970 Plymouth Road Runner Superbird is your machine. Developed specifically for NASCAR dominance, its outrageous aerodynamic features included a pointed nose cone and a towering rear wing. Under the hood, the standard engine was the potent 440 Super Commando V8, but the ultimate option was the legendary 426 Hemi V8. Equipped with twin Carter carburetors, the Hemi was officially rated at 425 horsepower, though dyno tests often showed actual output closer to 433 hp. Car and Driver magazine tested a Superbird Hemi, recording a blistering quarter-mile time of 13.5 seconds at 105 mph – incredibly quick for its day, comparable to sports cars built decades later.
9: 1969 Chevrolet Camaro ZL1
Fittingly, Chevrolet produced only 69 examples of the ultra-high-performance 1969 Camaro ZL1, making it one of the rarest and most valuable classic American muscle cars ever built. Developed through Chevrolet’s special-order COPO (Central Office Production Order) system, the ZL1 was essentially a factory-built race car. Its heart was an all-aluminum 427 cubic-inch big-block V8, substantially lighter than the iron-block 427s. Officially, Chevrolet rated the ZL1 engine at 430 horsepower, but this was a significant understatement; dyno tests consistently revealed actual output exceeding 525 horsepower. With its potent engine, minimal weight, and purposeful appearance often featuring simple dog-dish hubcaps, the Camaro ZL1 was the fastest production car Chevrolet had ever offered. Properly set up examples were capable of running the quarter-mile in the low 11-second range. When these rare beasts surface at auction today, they command staggering prices, with one recently selling for over $1 million, according to Hagerty.
8: 1969 Dodge Charger Daytona
1969 Dodge Charger Daytona showcasing its extreme aerodynamic design
Easily identifiable by its pointed aerodynamic nose cone and a massive rear wing that looked like it belonged on a jumbo jet, the 1969 Dodge Charger Daytona was a radical machine born from the intense NASCAR “aero wars.” Designed purely for high-speed stability on banked ovals, its extreme modifications proved incredibly effective, making it the first car to officially break the 200 mph barrier in NASCAR competition. Dodge produced 505 units for homologation purposes, meaning a fortunate few could own a street version of this dominant race car. In road-legal trim, the Daytona was typically equipped with either the 440 Magnum V8 or the legendary 7.0-liter (426 cubic inch) Hemi V8, the latter officially rated at 425 horsepower. The Charger Daytona remains one of the most outrageous and iconic examples of classic American muscle engineering focused on ultimate speed.
7: 1969 Pontiac Firebird Convertible
While later Firebird Trans Am models would become famous for the “Screaming Chicken” hood decal (which didn’t debut until 1973 and wasn’t widely available until 1976), the earlier 1969 Pontiac Firebird Convertible was a stylish and potent muscle car in its own right. Sharing its F-body platform with the Chevrolet Camaro SS, the Firebird offered similar performance but with distinct Pontiac styling. It proved highly popular, with over 11,000 convertible units produced for the 1969 model year. In the internal GM performance rivalry, the Firebird eventually gained an edge over its Camaro cousin, particularly when equipped with Pontiac’s Ram Air engine options. The Ram Air III and Ram Air IV systems utilized functional hood scoops to feed denser, cooler air to the engine, boosting horsepower (by approximately 15 hp for the Ram Air III over the standard 400 H.O.) and performance, solidifying the Firebird’s place among desirable classic American muscle convertibles.
6: 1970 Dodge Challenger Convertible R/T
1970 Dodge Challenger Convertible R/T, a rare Mopar with Six Pack power
The 1970 Dodge Challenger marked Dodge’s entry into the pony car market, and the R/T (Road/Track) convertible represented the pinnacle of open-air performance for the model. One of the most potent engine options available was the now-legendary 7.2-liter (440 cubic inch) V8 equipped with the “Six Pack” induction system – three two-barrel carburetors. This engine provided formidable power and placed the Challenger R/T convertible in a very exclusive category of classic American muscle. Of the 2,921 Challenger R/T convertibles built for the 1970 model year, only an incredibly small fraction – just 99 cars – were factory-equipped with the powerful 440 Six Pack V8. Narrowing it down further, only 61 of those 99 Six Pack convertibles were built with the desirable four-speed manual transmission, making them exceptionally rare and highly sought-after by Mopar collectors today.
5: 1971 Plymouth ‘Cuda Convertible
By the early 1970s, the popularity of convertible body styles was waning, and insurance premiums for high-performance, big-block muscle cars were skyrocketing. This confluence of factors dramatically impacted the production numbers of some of the era’s most potent machines, including the 1971 Plymouth Hemi ‘Cuda Convertible. Plymouth produced only a dozen Hemi ‘Cuda convertibles in total for the 1971 model year. If you desire ultimate rarity within this already scarce group, seek out one equipped with the four-speed manual transmission – a mere three were ever built with this combination. The 1971 model year was also significant as it marked the final year Plymouth offered the legendary 7.0-liter (426 cubic inch) Hemi V8 engine. This extreme rarity, combined with the Hemi’s iconic status, makes the 1971 Hemi ‘Cuda Convertible one of the most valuable and coveted classic American muscle cars in existence.
4: 1992 Dodge Viper RT/10
First-generation 1992 Dodge Viper RT/10 roadster, raw V10 power
No list celebrating potent American performance cars would be complete without the raw, uncompromising 1992 Dodge Viper RT/10. Representing a modern reincarnation of the classic American muscle ethos, the Viper prioritized brute force and driver engagement above all else. Lurking beneath its dramatically long hood is a massive 8.0-liter V10 engine, developed with input from Lamborghini (then owned by Chrysler), churning out 400 horsepower and a formidable 450 lb-ft of torque. What truly set the original Viper apart was its complete lack of electronic driver aids. There was no Anti-lock Braking System (ABS), no traction control, and not even airbags in the initial models. Mated exclusively to a manual transmission, the Viper RT/10 demanded respect and skill from its driver. It was, and remains, a pure, visceral driving machine for those brave enough to tame its V10 power.
3: 1965 Shelby G.T.350R Fastback
Carroll Shelby’s relentless pursuit of maximum performance combined with track-ready handling found perhaps its purest expression in the 1965 Shelby G.T.350R. Based on the Ford Mustang Fastback, Shelby American transformed the pony car into a legitimate race car for the street. The “R” designation stood for “Race Spec,” signifying that these cars were built in compliance with Sports Car Club of America (SCCA) production racing regulations. Shelby produced 572 examples of the G.T.350 Fastback in 1965, with only 34 of those being the ultra-rare, competition-focused “R” models. These cars featured a modified 289 V8, suspension upgrades, weight reduction, and aerodynamic enhancements. Owners could literally drive their G.T.350R from the dealership straight onto the racetrack and be competitive. One famous example dominated its class in 1968, winning an incredible 32 out of 54 SCCA races entered, cementing the G.T.350R’s legacy as a truly dominant force in classic American muscle road racing.
2: 1969 AMC AMX/3
Stunning mid-engined 1969 AMC AMX/3 supercar prototype
Arguably the most exotic and visually stunning vehicle on this list, the AMC AMX/3 was American Motors Corporation’s ambitious attempt to create a world-class, mid-engined sports car capable of competing with European thoroughbreds like the De Tomaso Pantera. Inspired by contemporary Italian designs, AMC penned achingly beautiful lines for the AMX/3. Its engineering was equally impressive, spearheaded by the legendary Giotto Bizzarrini (of Ferrari 250 GTO fame). Unlike traditional front-engined classic American muscle, the AMX/3 featured a potent AMC 6.4-liter (390 cubic inch) V8 mounted behind the cockpit for optimal weight distribution and handling. Despite investing a significant sum (estimated at $2 million then, roughly $15 million today) into development and producing several prototypes, AMC ultimately canceled the project due to rising costs and changing market conditions. Only six AMC AMX/3s were ever completed, making each example incredibly rare and valuable, with valuations often exceeding $750,000.
1: 1967 Shelby Cobra 427 Super Snake
Carroll Shelby’s mission was to create road-going cars with truly monstrous performance, and the 1967 Shelby Cobra 427 Super Snake stands as perhaps the ultimate, most terrifying embodiment of that goal. Representing the absolute pinnacle of Cobra performance, Shelby American built only two Super Snakes. One was tragically destroyed in an accident, leaving only one survivor: the breathtakingly curvaceous, blue example pictured. This unique vehicle sold at auction in 2021 for a staggering $5.5 million. The buyer acquired not just a beautiful car, but a legend powered by a 427 cubic-inch Ford V8 engine that Shelby elevated to mythical status by adding twin Paxton superchargers. The resulting power output was claimed to be a positively terrifying 800 horsepower – an astronomical figure for a lightweight roadster in the 1960s. The sole remaining Super Snake is arguably the wildest, most extreme example of classic American muscle ever conceived.
