The muscle truck represents the most curious of segments in all the automotive industry in that they don't actually sell that well, but manufacturers keep churning them out. That's actually a good thing because they are cool as hell, and there ain't nothing wrong with feeding a niche market while keeping an underground movement simmering. There's actually something very alluring about taking a pickup, which is generally associated with knuckle-busting blue-collar hard work, and giving it some elegant upper-crust supercar-like performance.This is, again, a very limited market that attracts a special kind of buyer who wants the practicality of a pickup with the romanticism of excessive and unnecessary power. Most people who are drawn to high-performance rides opt for either a wicked muscle car or a flashy sports car, but the muscle truck buyer wants to keep it real as well as keep it real fast. Because these high-powered pickups are often produced in small numbers, there are quite a few that people have forgotten about, and it's time to get reacquainted with some of the most killer supercars with truck beds. 1989 Dodge Shelby Dakota Power: 175 HP/270 LB-FT Mecum Carroll Shelby is most famous for tearing Enzo Ferrari a new one at the 24 Hours of LeMans as well as his suped-up Mustangs, but many people forget he ended his career making Dodge vehicles suck less. In 1989, Shelby applied his skill to the Dodge Dakota first by swapping out the standard 125-horsepower V6 for a 5.2-liter Magnum V8 that gave it an additional 50 ponies. He jazzed up the interior with a leather-wrapped steering wheel and Shelby logos and inserts galore.The exterior saw the most dramatic change with special graphics, a blacked-out front grille including an air dam with integrated fog lamps, and the iconic fiberglass "light bar" behind the cab. Most trucks in '89 had 0-60 mph times that wouldn't even be good quarter-mile ETs, so the 15 seconds it took the Shelby Dakota to travel 5,280 feet made it seem like a sports car. 1978 Dodge Li'l Red Express Power: 225 HP/295 LB-FT Mecum With flared sides, chrome exhaust stacks, and an aggressive, muscular stance, the 1978 Dodge Li'l Red Express is arguably the most underrated truck of all time. Also, it was the fastest American-made vehicle, even peppier than the Chevrolet Corvette, produced that year.Thanks to a little quirk, the Li'l Red Express was exempt from equipping a performance-sapping catalytic converter, while all others languished in the malaise of the Dead Horsepower Era. Its 360ci V-8 was good for 225 horsepower and around 295 pound-feet of torque, which propelled it to a mid-7-second 0-60 time and made it the quickest production vehicle to hit 100 MPH in '78. Dodge only built 2,188 of these babies for '78, so not a lot of people remember them, but the added bonus of their rarity makes for a killer collector truck. 1991 Chevrolet 454 SS Power: 255 HP/405 LB-FT Mecum A 1991 Ford Mustang GT could run a quarter-mile in the mid-15s, which was sufficiently badass for the day. A 1991 Chevrolet 454 SS could match that ET, but it was a pickup truck, not a muscle car, so that's actually even more badass. Chevy took a regular cab, short-bed C1500 pickup, and dropped in a 255-horsepower 454ci V-8, creating one of the first modern muscle trucks.The engine was a far cry from the ultimate 450-horsepower 454 LS6 V-8 that made the 1970 Chevelle SS a legend, but times were much different in the early '90s, and the 454 SS truck carved out its own legacy as one of the most powerful vehicles of the year. With a scant production run, it's understandable if most people forgot about this serious performance truck. 1991 GMC Syclone Power: 280 HP/350 LB-FT Mecum The same year Chevy got into the muscle truck business, GMC said, "hold my beer" and showed 'em what a true high-performance pickup was all about. The 1991 GMC Syclone was not only the fastest production truck at that point, but smoked just about everything on the road that year. With a 4.3-liter turbocharged V-6 that produced 280 horsepower and 350 pound-feet of torque, the Sonoma-based truck was a legitimate 13-second ride.This truck could beat a Nissan 300ZX Twin Turbo, hang with a Porsche 911 Turbo, and, astonishingly, was only two-tenths of a second slower than a first-gen Dodge Viper RT/10. Like too many awesome muscle trucks, the '91 Syclone was built in extremely limited numbers, 2,995 units to be exact, so it's relatively obscure, but no less amazing. 2003 Chevrolet Silverado SS Power: 345 HP/380 LB-FT Bring a Trailer In response to the 2001 Ford SVT Lightning, which we'll get to in just a second, Chevrolet unleashed their own version of a high-performance full-size truck with the 2003 Silverado SS. While not quite as potent as the Ford, the Silverado SS was still a monster street truck. With a 345-horsepower 6.0-liter V-8, this pickup could reach 0-60 in 6.8 seconds and run a quarter-mile in 14.8 seconds according to a Car & Driver test spin. A non-SS Silverado 1500 was roughly two seconds slower, and the same goes for the Ford F-150, while the SS was still a second faster than a Dodge Ram 1500 with a Hemi V-8. This was definitely the truck to beat in 2003. 1965 Dodge Custom Sports Special Power: 365 HP/470 LB-FT Dodge From 1964-1967, Dodge offered the high-performance Custom Sports Special package on their D-Series pickups, which is the first example of a muscle truck. 1965 is significant because that's when the iconic 426 Max Wedge V-8 was available for the CSS, making it one of the most insane trucks of all time. While not quite as lethal as the dual-quad versions of the 426 that made a legend out of the Plymouth Sport Fury, the 365 horsepower of the single four-barrel carburetor '65 CSS was good enough to make the truck badder than most muscle cars of the year, including Mustangs, GTOs, and Chevelles. This truck is so rare that we couldn't find a single example of one ever being sold at auction or in a private sale, and since it's like it never existed, most people didn't forget about it, they never knew it was a thing in the first place. 2001 Ford SVT Lightning Power: 380 HP/450 LB-FT Mecum Ford introduced a high-performance variant of their F-150 full-size pickup in 1999, known as the SVT Lightning. Originally, it featured a 360-horsepower 5.4-liter Supercharged V-8, which was pretty awesome, but in 2001, it became thoroughly spectacular. Employing a larger air inlet, bigger mass-air meter, upgraded intake manifold, more efficient intercooler, and a shorter rear axle ratio, the '01 SVT Lightning cranked things up to 380 horsepower and 450 pound-feet of torque. The SVT Lightning boasted a 5.8-second 0-60 time, 13.9-second quarter-mile ET, and a top speed of 147 MPH, but independent testing, including Car and Driver, showed those were conservative numbers and the 2001 SVT Lightning was actually a couple ticks quicker. 2004 Dodge Ram SRT-10 Power: 500 HP/525 LB-FT Mecum Having already invented the muscle truck, Dodge set out to create the supertruck in 2004 and totally nailed it with the Ram SRT-10. Fitted with the same 8.0-liter V-10 from the Viper, this totally bonkers pickup was the baddest thing on the streets in the early aughts. Its 4.9-second 0-60 mph and 13.6-second quarter-mile were impressive, but its top speed was the real star of the show.On February 2, 2004, the Guinness Book of World Records named the Ram SRT-10 the world's fastest production pickup, when a bone stock version averaged 154.587 MPH on two passes. With the more recent 702-horsepower supercharged Hemi Ram TRX, a lot of folks have forgotten about the SRT-10, but Dodge has been doing the supertruck thing for decades. 2008 Toyota TRD Supercharged Tundra Power: 504 HP/550 LB-FT Bring A Trailer You can be excused if you never heard of the 2008 Toyota TRD Supercharged Tundra, because it wasn't an actual model or even trim level. It was a dealer-installed Eaton TVS supercharger that transformed the half-ton Tundra into a full-blown supertruck. Wrenching the supercharger onto the 5.7-liter i-Force V-8 took it from 381 horsepower to 504 furious ponies. Its 4.4-second 0-60 time made it quicker than a Mustang GT, Challenger SRT-8, and even a Porsche Carrera.Because this wasn't a production vehicle, there are absolutely no sales numbers, but enthusiasts estimate that maybe a couple of thousand to possibly just hundreds were ever sold. The rarity of the TRD Supercharged Tundra and the fact that Toyota didn't include a killer graphics package with it are why the ultimate supertruck is nearly completely anonymous. 2019 Ford F-150 Nitemare by Roush Power: 650 HP/610 LB-FT Roush Performance The 2019 Roush Nitemare F-150 is the only truck on this list that isn't an official product of its original manufacturer, but it is far too awesome to continue giving the cold shoulder. Custom-ordered Ford F-150 trucks left the factory and headed over to Roush Performance for serious upgrades in both performance and style. The standard 5.0-liter V-8 was paired with a Roush TVS supercharger, making for a literal nightmare 650-horsepower street assassin.There are performance upgrades throughout, and the exterior is treated to some slick Roush graphics, while the truck is dropped a couple of inches and fitted with custom 22-inch wheels. A 4×4 SuperCrew Nitemare could go from 0 to 60 mph in 4.1 seconds, while a Regular Cab shaved two-tenths of a second off that time, putting it on par with muscle cars and sports cars for straight-line acceleration.Sources: Car and Driver.
