A rare custom American Muscle Cars known as "Hellfish" is so thoroughly re-engineered that it makes a factory muscle car look like a science fair project — and it just sold for an insane amount of money on Bring a Trailer, squarely in the territory of new Ferrari Romas and Lamborghini Huracáns. A Custom 1972 'Cuda With An Obscene Price Tag Bring A TrailerBuilt between 2014 and 2015 by the Roadster Shop of Mundelein, Illinois, the metallic gray coupe started life as a humble 340ci-powered 'Cuda and ended up as something that frankly has no business existing — according to some people. The shop dropped in a Mopar aluminum-block 7.0-liter "Gen III" Hemi stroker, bolted twin turbochargers to it and connected the whole package to a Bowler-built Tremec T56 six-speed Carbon Edition gearbox. Hot Rod magazine ran a feature in November 2015 and measured 1,241 horsepower and a tire-obliterating 1,027 lb-ft of torque. For context, that is more than double the output of a new Dodge Challenger Hellcat. That is also, to be clear, absolutely unhinged for a car whose roof is roughly level with your hip.Bring A TrailerA custom Fast Track chassis sits beneath the steel body, paired with Hyperco coilovers, Penske double-adjustable shocks at all four corners, tubular front control arms, a four-link rear with Panhard bar, Woodward rack-and-pinion steering, and Wilwood six-piston front brakes.Bring A TrailerOn the outside, the shop shaved the emblems, door handles, and trim, grafted on a 1970-style grille and taillights, cut and re-fitted the bumpers tighter to the body, and painted the whole thing in metallic gray with a satin black hood. A red "Hellfish" badge sits in the grille. A demonic fish graphic adorns the tail panel. It is not subtle. It was not designed to be subtle.Bring A TrailerInside, Recaro bucket seats are wrapped in black leather, red Schroth Racing harnesses stand ready for commitment, and a Spek Pro gauge cluster reads up to 180 mph — a number that, given the power output, no longer seems like an exaggeration.Interestigly, the vehicle has no odometer, and true mileage is unknown. Given that it makes 1,241 horsepower, perhaps the more pressing unknown is how many rear tires it has consumed since 2015. However, this car seems to be worth a lot of money, and that is why it just sold for a staggering $330,000. How Much Do Regular Plymouth Baracudas Go For Today? Mecum AuctionsTo put the Hellfish's $330,000 sale price in perspective, it helps to know what a standard '72 Barracuda actually trades for on the open market.Unrestored, driver-quality examples — think faded paint, tired interiors, and original small-block engines still doing their best — typically change hands anywhere between $20,000 and $40,000 depending on condition and originality. Nice, fully restored drivers in desirable colors with matching numbers sit in the $50,000–$80,000 range. Concours-quality restorations of the most sought-after cars, particularly original big-block cars with documented history, can push past $100,000 — but that takes a genuinely exceptional example to get there.The 1972 model year is also worth noting as a slight weak point in the Barracuda's collector hierarchy. The '70 and '71 cars — with their aggressive "E-body" styling at its freshest and more powerful engine options before emissions strangled the fun — command a consistent premium. The '72s are loved, but they sit a rung below their earlier siblings in most collector circles.Which makes the Hellfish's $330,000 result all the more remarkable. It sold for roughly eight times what a pristine, numbers-matching '72 'Cuda would bring — and the reason is obvious. You're not paying for a Barracuda. You're paying for a 1,241-horsepower, Roadster Shop–built, Hot Rod–featured, twin-turbo monster that just happens to wear Barracuda sheet metal. At that point, the sticker on the grille is almost beside the point.
