Most custom trucks hide the interesting parts. This 1948 Chevrolet 3100 Custom Pickup, currently live on Cars & Bids, puts them under a row of eight individual throttle bodies. The truck is a Tre5 Customs build wrapped around a modified Roadster Shop Revo chassis, powered by a GM Performance LS3 V8, and it is a long way from the usual bagged-and-billet pickup.
The auction is scheduled to end Monday, October 26 at 2:42 p.m. Eastern, according to the listing. When we checked Tuesday morning, bidding stood at $10,000 after 12 bids. The seller is a dealer, AMF1 in Seal Beach, California, representing the titled owner.
The chassis does the heavy lifting
The 3100 sits on a Roadster Shop Revo chassis, a purpose-built platform that replaces the original frame rather than adapting it. According to Barrett-Jackson's Scottsdale listing for the same VIN, the chassis uses custom front and rear links, a billet Watts link and Ridetech shocks, with AccuAir e-Level air suspension handling ride height. Braking comes from Baer 14-inch drilled and slotted rotors with six-piston calipers. The Cars & Bids equipment list adds a Currie rear axle and a Mustang II steering box.
An LS3 with eight-stack induction
The engine is a 6.2-liter GM Performance LS3 V8 paired with a 4L60E four-speed automatic. What sets it apart is the Borla eight-stack induction, one throttle body per cylinder, managed by a Holley Terminator X system. Ultimate headers feed a custom 3-inch TIG-welded exhaust with Black Widow mufflers. Neither listing states a horsepower figure, so any output number would be a guess. For context, the stock LS3 crate engine is rated at roughly 430 horsepower, and the same basic V8 powers the LS3-equipped 1954 Chevy 3100 we covered earlier.
The eight-stack is mostly a show of engineering for its own sake, in the same spirit as the supercharged LS3 Chevelle restomod and the Hayes-built 1967 Corvette with its 540-horsepower LS3: modern V8 hardware dressed in classic sheet metal.
Bodywork and cabin
The truck is finished in PPG Pearl White. Barrett-Jackson's description lists shaved body panels, flush-fit glass, frenched LED lighting, a one-off roll pan, custom running boards and a modified front bumper. A Mar-K wood bed kit and hidden air components keep the bed clean. Inside, the factory-style bench seat is trimmed in Hydes leather in a Cognac tone, with Dakota Digital instruments, a Billet Specialties steering wheel, Restomod Air climate control and a Pioneer head unit with JL Audio speakers. The odometer shows 512 miles.
What is documented and what is claimed
The build details above, down to the chassis and engine, match between the Cars & Bids listing and Barrett-Jackson's 2026 Scottsdale docket, which shows the same VIN as a no-reserve lot with a sold status. We could not see the sale price. The Cars & Bids listing says the truck is titled in California as a 1948 Specially Constructed vehicle and that the titled owner reportedly bought it in 2025. We could not reconcile that with the Scottsdale lot, so bidders should ask about the ownership timeline.
The listing also says the truck was shown at the 2020 SEMA Show. We could not confirm that independently. The only known flaw listed is a crack in one of the wooden bed slats, and build records and service invoices are included in the gallery. As always, the information comes from the seller, and bidders are responsible for verifying it.
The Advance Design generation Chevrolet introduced for 1947 was the brand's first all-new postwar truck, and builders have been reworking it ever since. Few have done it with eight throttle bodies and a bespoke chassis, and with bidding still near $10,000 and days to go, this one is worth watching.
