SEMA 2023: 1949 Chevrolet 3100 Pickup NautiD by Weaver Customs

The Las Vegas Convention Center encompasses more than 4.6 million square feet of floor space spread across multiple buildings. When the SEMA Convention comes to town, they occupy the entire facility. To say that the SEMA Show is big is an understatement. It is so big that it’s hard to see everything, even over multiple days.

If you spend all of your time in the convention halls, you might miss a great vehicle in one of the outdoor displays. At the 2023 SEMA Show, I saw this amazing custom Chevy pickup truck in the Adam’s Polishes booth in front of the Central Hall.

The truck is a 1949 Chevrolet 3100 pickup nicknamed “NautiD.” The truck was built by Weaver Customs in West Jordan, Utah.
The crisp body lines of the “Advance Design” styling really come through in this truck, which has shaved trim, drip rails, wipers, and mirrors. The non-metallic gray color is also eye catching, which is actually Axalta Chalk Grey. I spent a few minutes admiring the truck up close.

The truck has a ton of custom touches including a custom bed, flush mount glass, shaved and smoothed body, and a restyled front and rear end. There are more than 100 custom billet machined pieces on the truck.
Under the hood, the original straight-6 engine has been replaced with a 6.6-liter Duramax LLM diesel engine with twin turbochargers! This is coupled to an Allison 6-speed transmission. A custom Flowmaster exhaust keeps the power flowing smoothly. The Duramax engine is an interesting choice for a build, but it fits the spirit of the truck as a workhorse.

The custom-built chassis has an independent front suspension with a 4-link rear suspension with Ridetech components. A narrowed 9-inch rear end puts the power to the rear wheels. Speaking of which, the wheels are one-off designed which are 18×8 in the front and 20×12 in the rear with Michelin tires.

The interior has a minimalist design aesthetic blended with modern amenities. The truck has air conditioning, a Kicker stereo, power windows, and even 2 cup holders in the center console. A pair of custom Dakota Digital gauges provide essential information to the driver. The interior was done by Innovation Custom Interiors in Ogden, Utah who wrapped the seats and console in Guinness Hydes leather.

This Chevy 3100 is a 74 year old truck that has been completely reimagined with modern power, handling, and amenities. With this full restoration and upgrade, I’d say the truck is ready to take on the next 70 years and beyond.
