The 1983 Chevrolet Camaro IMSA Race Car represents a significant chapter in American motorsport, serving as the final competitive vehicle campaigned by the legendary Don Yenko. This car participated in the 1983 IMSA Kelly America Challenge, carrying the weight of a historic racing name.
A Dillon Enterprises Engineering Feat
Constructed by the noted experts at Dillon Enterprises of Indiana, this vehicle features a full tube chassis designed for maximum rigidity. It was driven by a talented roster including Jerry Thompson, Chris Thompson, and Don Yenko himself. During the 1983 season, this setup secured a second-place finish at Pocono and a third-place podium at Lime Rock.
Race Ready Preparation and Storage
The car remained in professional storage from 1987 until 2005, preserving its structural integrity and historical components. Recently, it underwent a thorough mechanical review, including compression and leak-down tests to ensure its track readiness. Furthermore, it rides on Hoosier slicks from 2015, maintaining an aggressive stance that reflects its competitive nature.
Specialized Track Hardware
The steering system utilizes a precise rack and pinion setup for improved feedback during high-speed maneuvers. A dry sump oil system provides consistent lubrication under heavy lateral forces on the track. These professional-grade components demonstrate that this Camaro was built for endurance and high-level performance rather than simple street use.
Functional Race Cockpit and Chassis
Inside the black interior, the focus remains entirely on competition and driver safety. The quick-change rear end is currently equipped with 3.55 gears, allowing for rapid adjustments based on specific track requirements. Additionally, the multi-tone White, Orange, and Black exterior graphics remain a vivid reminder of its period-correct racing livery.
V8 Engine Specs and Mechanical Power
The heart of this 1983 Chevrolet Camaro IMSA Race Car is a race-prepped 310 CI V-8 engine rebuilt by Joe Wambolt. This high-revving unit is paired with a rugged 4-speed manual transmission designed for the rigors of road course racing. This combination of a lightweight tube chassis and a potent small-block V-8 ensures a visceral and engaging driving experience on any circuit.
Historic IMSA Competition Summary

It offers a rare opportunity for collectors to own a podium-finishing vehicle with documented provenance from a golden era of racing.
