It is offered on Bring a Trailer with bidding at $23,000 and two days remaining. The hook is the blown big-block and the sheer presence of a mid-1960s full-size Plymouth built as a modern-driving muscle car.1964 Plymouth Sport FuryBring a TrailerWhat it's worth right nowValuing this car is not a matter of stock comps, because it is a one-off custom rather than an original example. For reference, Classic.com and auction data show 1964 Furys spanning a wide range, from under $10,000 for projects to $77,000 for the rare, factory-correct 426 Max Wedge cars, with clean driver-quality examples generally listing in the $25,000 to $40,000 range. This car sits in its own category as a supercharged restomod.AdvertisementAdvertisementWhat matters here is the build. A blown 440, a Tremec five-speed, a Dana 60 rear end, and four-wheel disc brakes represent a significant investment that comfortably exceeds the current bid, which effectively underwrites the car's floor. Working against the top end are its niche appeal, since a full-size unibody Plymouth is a less mainstream canvas than a Charger or Road Runner, and a handful of cosmetic and functional rough edges.1964 Plymouth Sport FuryBring a TrailerAt $23,000 with two days left and only a couple of bids, it is tracking at the low end of where a car like this should land, and it has room to climb into the high $20,000s or beyond if it drives as well as its spec suggests.Condition and detailsThe car is finished in red with a white roof over a red and white vinyl interior, riding on 15-inch American Racing Torq Thrust wheels with Firestone white-letter tires, and it presents as a purposeful street machine. Honest flaws are visible in the listing, including paint blemishes on the rear left, a cracked steering wheel rim, and wrinkles in the headliner, so this is a driver rather than a show car.The supercharged 440 was assembled by PK Machine in 2007 and topped with a Blower Shop supercharger and twin Demon carburetors, with an engine build sheet included. The seller relays a builder estimate of around 709 horsepower at the crank, which is not independently verified. A prospective buyer should note that the clock, tachometer, and boost gauges are listed as nonfunctional, and that a commenter observed the driving video did not clearly demonstrate the car pulling hard through the rpm range, so confirming how it actually drives is the single most important step.1964 Plymouth Sport FuryBring a TrailerThe car carries a clean Montana title with a lien released in 2014, and the seller, an experienced Bring a Trailer lister representing the owner, states that two shops went through the car and found no issues, attributing any underside residue to normal use. An in-person or third-party inspection is still the smart move given the custom nature of the build.The offerSpecificationDetailMakePlymouthModelSport FuryYear1964Mileage70,000 shown, not verifiedEngineSupercharged 440ci V8PowerBuilder-estimated 709 hp at the crankTransmissionTremec 5-speed manualDrive typeRear wheel drive with a Dana 60 rear endExterior colorRed with a white roofInterior colorRed and white vinylCurrent bid$23,000, with two days leftInterested in this 1964 Plymouth Sport Fury? View the listing here.What makes the Sport Fury uniqueThe Sport Fury sat at the top of Plymouth's full-size range in 1964, the sporty, bucket-seat flagship of a lineup that also produced some of the most feared cars of the early Mopar performance era. That was the year of the legendary 426 Max Wedge and the debut of the 426 Race Hemi, and while most Sport Furys left the factory with milder V8s, the model's clean, upright styling and big-car presence have made it a favorite base for customs and restomods.1964 Plymouth Sport FuryBring a TrailerThis example leans fully into that spirit. Rather than chase originality, its previous owner built it into a supercharged, manual-shifted brute, the kind of car the seller describes as a long-legged cruiser for Montana's open roads. It is a distinctly personal take on a big 1960s Mopar, trading concours correctness for a loud, torque-rich driving experience that stands apart from the more common muscle-car choices.My takeThis is a genuinely cool, characterful custom, and there is a lot to like about a supercharged 440 Sport Fury with a proper five-speed, a Dana 60, and disc brakes, because the hard parts are all here and the money spent building it clearly exceeds the current bid. If you want a big, loud, torque-rich Mopar that stands out at any cars and coffee, this delivers something most muscle cars cannot, and it does so at a price that looks like real value on paper.AdvertisementAdvertisementThe caveats keep it honest. I would place fair value in the $25,000 to $40,000 range for a sorted, well-driving example, so the current $23,000 bid is reasonable with room to rise, but the nonfunctional gauges, the cosmetic flaws, and especially the unanswered question of how it pulls under load mean this should be bought only after you have seen it run and drive, ideally through a third-party inspection. Do that, confirm the engine delivers on its build sheet, and this is a distinctive, big-power classic for sensible money.Disclaimer: This post is for informational purposes only.
