It’s also a multiple-award winning vehicle at Goodguys including the Truck of the Year Finalist and Top 10 Builders Choice.

Known as, “Grizzly” – this 1950 Chevrolet 3100 Supercharged LS3 Custom Pickup with TCI Chassis is the ultimate American Classic Truck. It was built by Streamline Custom Designs in Utah and debuted at the Goodguys Lone Star Nationals. In 2023, it was presented a Goodguys Builders Choice Award and Truck of the Year Early Finalist Award. It was also featured in Goodguys and TruckHub Magazine. It was showcased at the Hot Rod Alliance at SEMA. The vision of this build was to create a unique 3100 that defines luxury and performance.
The exterior of this 50′ Chevy 3100 is truly remarkable with its craftsmanship and attention to detail throughout. Rather than fight decades-old sheet metal, the team at Streamline started with new sheet metal including a Premier Street Rods 5-window cab, AMD hood and fenders, and a second-gen Mark-K bed. That allowed them to concentrate on making subtle body modifications like a shaved cowl, one-piece hood, custom inner fenders, frenched LED headlights, front valence, Kindig door handles, smooth running boards, radiused bed corners, molded taillights, a custom tailgate and a rolled rear pan. The bed was raised 3” and a set of mini-tubs were installed. The team also built custom front and rear bumpers from a 1968 Chevrolet Camaro. The laser straight body and precise gap lines highlight the iconic design. It was outfitted with a new one-piece windshield and door glass. The distinctive color started from Winterleaf Brown off a 1932 Ford and was customized to what now is referenced as Streamline Café Au Lait. The paint was applied to the highest standards and is exquisite. The oak bed floor is finished of multiple stain colors with smoothed stainless-steel strips and Crafty-B supplied the stylish gas cap. It rolls on Schott Split-Window 18×8 front wheels and 19×12 rear wheels that are mounted to Nitto yellow line tires. Everything on the exterior is in working order such as the lights, turn signals and horn. The wipers are for appearance only.

The interior of this 50′ Chevy 3100 is very tasteful with its unique design. Revolution stitched up the cabin by covering the dash, American Retro steering wheel, Procar bucket seats, center console and just about every interior panel in distressed leather. It was decorated with a microfiber suede headliner and German weave carpeting with molded floor mats. Some interior amenities include Dakota Digital gauges, Restomod air conditioning, power windows, JL Audio audio system including speakers and subwoofer, Ididit tilt steering column, cup holders, power outlet, USB ports, Clayton Machine Works shifter, handles and pedals. Everything in the interior is in working order such as the lighting, gauges, air conditioning an audio system.

The painted engine compartment is highly detailed throughout. The hood has custom brackets and pumps. To optimize engine set back within the chassis, the firewall was recessed 3” and was smoothed out. It’s powered by a Chevrolet Performance LS3 with Magnuson supercharger. It was dyno tested with 632 horsepower and 775 lb-ft at the rear wheels. Olds Rocket valve covers dress up the LS3 and the accessory drive is from Drive Junky. A combination of satin clear on the under hood sheet metal and custom Graphite Gray on the valve covers, supercharger and wheels provide nice contrast to the brown body paint. The front section of the passenger side was modified to conceal the supercharger fluid tank and the driver side now accommodates the cold-air induction tube. The engine is cooled by an aluminum radiator with electric fan which is covered by a custom radiator support panel. The engine breathes through Speed Engineering headers and Flowmaster mufflers with electric exhaust cut outs. The engine is coupled to Chevrolet Performance 4L75E automatic transmission and Currie 9” rear end with 3.73 gears.

The undercarriage is also highly detailed throughout. It’s equipped with a new TCI Engineering Chassis with power rack and pinion steering, tubular control arms, heavy duty sway bars, four-link rear and Ridetech coil-overs shocks. It’s also equipped with power Wilwood four wheel disc brakes and ESTOPP electric emergency brake. This vehicle has been driven over 1,150 miles and performs excellent.
