The 1937 Chevrolet Custom Street Rod represents the absolute pinnacle of high-end automotive craftsmanship and raw mechanical aggression. This particular all-steel body example emerged from a no-expense-spared build, combining classic pre-war lines with massive modern power. Since the customization was completed, the vehicle has traveled only 1,546 miles, ensuring its pristine show-quality condition. Under the sleek gray exterior sits a supercharged small block engine that generates a staggering 550 horsepower. This incredible machine is scheduled to cross the block at the Glendale 2026 auction this March. It stands as a testament to the enduring appeal of the street rod movement in America.
All Steel Body and Polished Gray Aesthetics
Finding a 1937 Chevrolet Custom Street Rod with an all-steel body is becoming increasingly difficult in the collector market. The exterior is finished in a sophisticated shade of gray that emphasizes the smooth curves of the original design. Polished aluminum and chrome accents are featured throughout the exterior, providing a brilliant contrast to the paintwork. This build avoids the common fiberglass shortcuts, maintaining the authentic weight and feel of a vintage steel car. Every panel gap is tight, and the finish reflects the high level of investment poured into this project. Custom touches ensure it stands out in any sea of traditional hot rods at a show.
Hand Fabricated Interior and Custom Leather
The cabin of this 1937 Chevrolet Custom Street Rod is a masterpiece of hand-fabricated luxury and ergonomic design. Gray leather covers every surface, from the supportive bucket seats to the custom door panels and dashboard. This interior was created specifically for this build, ensuring a unique environment that matches the exterior color palette. Modern comforts are integrated seamlessly, allowing for a relaxed driving experience despite the massive power available. The attention to detail in the stitching and material choice reflects a truly professional level of upholstery work. It provides a tactile connection to the craftsmanship that defines high-tier street rod builds.
Advanced Chassis and Suspension Engineering
Beneath the steel skin, the chassis has been extensively modified to handle the 550 horsepower output reliably. A Scott’s Hot Rods custom independent front suspension provides modern handling characteristics and a lowered stance. In the rear, a 4-bar suspension setup with coilovers ensures the tires stay planted during hard acceleration. Rack and pinion steering replaces the original steering box for much more precise feedback on the road. This combination of parts transforms the 1930s platform into a machine that handles like a modern sports car. These upgrades are essential for safely managing the high-performance powertrain during spirited driving sessions.
Wilwood Braking and Detroit Locker Differential
Stopping power is provided by a Wilwood four-wheel disc brake system featuring polished four-piston calipers at each corner. These high-performance binders ensure the street rod can shed speed as quickly as it gains it. Power is delivered to the ground through a chrome 9-inch Detroit Locker rear differential, built for maximum durability. This differential is a favorite among drag racers and high-end builders for its ability to handle immense torque. The polished finish on the rear housing adds another layer of detail to the highly finished undercarriage. Every mechanical component has been chosen for both its strength and its visual appeal.
Supercharged 350 V8 Performance Specifications
The mechanical heart of this build is a supercharged 350 CI small block V8 engine producing 550 HP. A massive Weiand 671 supercharger sits prominently atop the engine, providing a constant supply of forced induction. Chrome and polished aluminum components fill the engine bay, creating a dazzling display of high-performance jewelry. An automatic transmission manages the power, allowing the driver to enjoy the visceral soundtrack of the blower whine. This powertrain is not just about show, as the 550-horsepower rating provides world-class acceleration and speed. It is a cohesive unit built to provide reliable and explosive performance on demand.
Summary of the All Steel Street Rod
This 1937 Chevrolet Custom Street Rod is a rare find that combines an all-steel body with elite-level components. The supercharged 350 engine and Weiand blower make it a serious performer in any automotive circle. Every detail, from the Scott’s Hot Rods suspension to the Wilwood brakes, speaks to a professional build quality. The gray leather interior and matching paint provide a timeless and sophisticated aesthetic for the next owner. With low miles since completion, it remains in showroom condition and ready for the Glendale stage. It serves as a premier example of what happens when engineering meets high-end automotive art.
