Late-Forties Legacy
Chevrolet introduced the Advance Design series in 1947 as its first major automotive redesign following World War II. Built with a focus on interior room and driver visibility, these trucks became commercial mainstays. The 3800 series designated the heavy-duty 1-ton platform, configured with a wheelbase designed to handle larger payloads than the standard half-ton models. This particular 1949 model preserves that heavy-duty commercial scale while integrating modern powertrain and chassis systems.
The Build Overview
This 1949 Chevrolet 3800 is a customized, long-bed restomod that underwent a multi-stage build process. The initial custom build concluded in 2003, with a second phase of targeted engine compartment fabrication completed in 2017. The vehicle shows 800 miles on an inaccurate aftermarket odometer, making its true mileage unknown (TMU). Offered by a dealer out of West Chester, Pennsylvania, the truck includes build records and carries an Antique Vehicle branded Pennsylvania title.
The Heartbeat: Engine & Drivetrain
The engine bay is detailed with a smoothed firewall, a fabricated radiator cover, and a classic “batwing” air cleaner assembly, all color-matched to the truck’s silver exterior during the 2017 fabrication phase. Power comes from a 383 cubic-inch stroker V8 equipped with an Edelbrock aluminum intake manifold, a 4-barrel carburetor with an electric choke, and an HEI distributor. Dress-up items include Holley Vintage Series valve covers with raised Chevrolet script, while spent gases exit via coated Hooker headers feeding into a dual exhaust system routed out the rear. Cooling is handled by an aluminum radiator, and power is sent to the rear wheels through a Turbo Hydra-Matic three-speed automatic transmission and a 10-bolt rear differential.
Interior Comforts
The cabin has been upgraded with a complete re-trim and modern instrumentation. Driver and passenger sit in replacement bucket seats upholstered in black Ultraleather with white patterned cloth inserts, complemented by custom matching door panels and a coordinated center console with integrated cup holders. Driver inputs are managed via an aftermarket steering wheel mounted to a tilting column, paired with a Gennie floor shifter. Comfort and entertainment are provided by an aftermarket air conditioning system and a Kenwood stereo unit wired to kick-panel speakers. The custom body-colored dashboard houses a full suite of AutoMeter gauges, including a 120-mph speedometer, a tachometer, and secondary indicators for water temperature, oil pressure, voltage, and fuel level.
The Sheetmetal: Exterior Styling
The factory commercial body lines are finished with custom paint detailing and altered proportions. The sheetmetal was repainted in metallic silver in 2003, featuring gray ghost-style flames across the front end alongside custom pinstriping and tailgate lettering. Body modifications include fiberglass rear fenders, smoothed running boards, dual cowl-mounted side mirrors, and tinted glass, all set off by LED taillights and a bright chrome factory-style grille. The 4×8-foot utility cargo bed features a custom-hinged aluminum floor panel that lifts for chassis access, alongside a separate front storage compartment housing an aluminum fuel tank under a hinged cover. The truck rides on 16-inch chrome Rally wheels wrapped in 225/60 Bridgestone Turanza LS-V tires.
The Foundation:
The original heavy-duty 1-ton commercial chassis has been extensively altered to improve steering accuracy and ride quality. Up front, the factory straight axle was replaced by a Mustang II-style independent front suspension assembly featuring integrated structural mounts on an updated crossmember. Steering changes include a power-assisted rack-and-pinion system, while stopping power is upgraded via a power-assisted four-wheel disc brake system.
