Blown 468 and a Straight Axle: 1955 Chevy Bel Air Gasser Chases Bids on Hagerty MarketplaceA jet-black, supercharged 1955 Chevrolet Bel Air built in period-correct gasser style is drawing serious bidder attention on Hagerty Marketplace, where the no-reserve sale has already topped $26,000 with several days left on the clock. The two-door post sedan is part of the George G. Trebbi Collection, a group of custom, loud, and fast machines being sold in tribute to the late Cincinnati collector who built his life around classic Chevrolets.The gasser look traces back to the NHRA's Gas classes of the mid-1950s, when drag racers needed a way to get sticky, wide, low-traction tires to hook off the line. Racers found the answer in a straight front axle, a raised nose, a lowered rear end, and a stripped-down body, all working together to shift weight rearward under hard acceleration. The formula caught on so widely that "gasser" became shorthand for the whole aggressive, wheels-up look, regardless of what NHRA class a particular car actually raced in.This particular Bel Air leans hard into that formula. It rides on a dropped straight front axle with a tilt fiberglass front clip, wears a flat-black hood cut for a supercharger scoop, and rolls on a period-style combination of Mickey Thompson front rubber and Firestone slicks out back. Under that hood sits a 468-cubic-inch big-block Chevy topped with a Roots-style 6-71 supercharger and a pair of Holley double-pumper carburetors, feeding a Richmond Super T-10 four-speed manual and a 9-inch rear axle with 4.10 gears. Inside, a roll bar, Chevelle bucket seats with harnesses, a Hurst shifter, and a bank of underdash gauges complete the drag-strip theme, and a handwritten dyno note included with the car's documentation claims 668 horsepower on pump gas, though there's no timeslip to back up a quarter-mile number.AdvertisementAdvertisementBuilt by H.S. Dreams in Omaha, Nebraska, and acquired by the Trebbi family in 2020, the car is now being sold at no reserve through a Broad Arrow specialist, a Hagerty subsidiary acting as the seller's agent. Bidding has climbed steadily since the auction opened in late July, with the high bid sitting at $26,679 after eighteen bids, and the sale is scheduled to close August 10.Because this Bel Air has been so thoroughly reworked, comparing it to a stock car only tells part of the story. Hagerty Valuation Tools price a numbers-matching 1955 Bel Air two-door sedan with the optional 180-hp four-barrel V8 at roughly $34,500 in #3 (Good) condition, while a clean convertible with the same engine can bring closer to $57,400. A gasser build like this one trades that kind of factory-correct value for something harder to price on a chart: a documented period-style hot rod with a big-inch blower motor and a well-known collection history, the sort of car whose worth often comes down to how badly a given bidder wants that exact look and story.This is far from the only Hagerty Marketplace find with roots in the same era. Motorious recently covered a hand-built 1959 Chevrolet 150 rat rod nicknamed Tetanus, a similarly no-frills take on a Tri-Five-adjacent Chevy, as well as a fuel-injected, big-brake 1959 Corvette that pulled serious bids on the same platform. For readers who prefer their Chevrolet horsepower a little more modern, a 2017 Camaro ZL1 built by RPM Motorsports to the tune of 865 horsepower has also been chasing bids on Hagerty Marketplace this summer.With no reserve, an active bidding war, and days still left on the clock, this 1955 Chevy gasser looks set to be one of the more memorable pieces of the Trebbi Collection to find a new home.⚡️ Read the full article on MotoriousSign up for the Motorious Newsletter.
