Gasser-Style Supercharged 468-Powered 1955 Chevrolet Bel Air 2-Door Sedan

Description

OFFERED WITHOUT RESERVE

If it was loud, fast, or custom, you knew Trebbi—er, trouble—was coming. Born and raised in Cincinnati, Ohio, George Trebbi was known for his insatiable quest for knowledge in business, history, and classic cars. He loved sharing his knowledge and passion with friends and family, and he could frequently be found taking his grandchildren for a joyride in one of his cherished Chevys. Hagerty Marketplace is proud to present The Trebbi Collection: custom, fast, and loud—and all presented without reserve. * * *

In the mid-1950s, the NHRA started the Gas division to attract more street cars to its drag strips. And it worked: by the late ’50s, Gas had five different classes, from E/Gas to blazingly quick 9-second A/Gas racers. And soon, the word “gasser” was heard around racetracks and cruise spots.

The gasser look was a practical solution for dealing with the era’s primitive, stiff-sidewall slicks. By building a car that could efficiently shift weight rearward, racers could make those low-traction early slicks hook. So they used a lifted, lightweight straight front axle, lowered the rear axle height for better weight transfer, removed the front bumper (and often the grille), and used lightweight fiberglass body parts, including tilt front ends. The mean-looking result could be further enhanced with a tall tunnel ram intake, or a huge supercharger sticking out of the hood.

A 1955 Chevy gasser is a sight to behold. Combining the boxy first model year of the legendary 1955–57 “Tri-Five” series with the gasser’s purposeful modifications yields an incredibly aggressive look — especially with the Bel Air’s uplevel brightwork setting off sinister black paint.

This ’55 Chevy started life as a V8-powered Bel Air 2-door “post” sedan, and wears black paint with a flat black hood. A straight front axle and a modified rear suspension provide the signature gasser stance, with a front bumper delete, a tilt fiberglass hood, period tinted glass, and slicks and skinnies completing the look. Inside the rollbar-equipped interior are black bucket seats, a Hurst shifter, a dash-mounted tach, and additional gauges. And lurking under and over the hood is a 468ci big-block Chevy wearing fender well headers and topped by a Roots-type supercharger. That blown V8 sends torque through an aftermarket 4-speed manual transmission to a 9-inch rear end.

This 1955 Chevrolet Bel Air 2-Door Sedan Gasser is now represented at no reserve by a Broad Arrow Specialist with a clean Ohio title in the current owner's name.
