Mechanical Heritage and Shelby Registry History
Every genuine Shelby carries a story, and this 1966 Shelby GT350 Fastback is no exception. It was originally shipped to Broadway Motors in Kansas City and is now officially documented in the Shelby Registry. The restoration process prioritized authenticity, ensuring the vehicle retains its core identity while looking better than it did on the showroom floor.

Owners appreciate this historical traceability, as it provides peace of mind regarding the vehicle’s provenance and value over time. It stands as a well-preserved artifact of a legendary era.
Supercharged Induction and Matching Numbers
One of the most impressive aspects of this build is the matching-numbers 289 CI V-8 engine. It features a period-correct Paxton supercharger, a rare and highly desirable upgrade that significantly boosts power output. This forced induction system transforms the high-revving small block into a truly formidable force on the asphalt. The engine bay is a showcase of mid-sixties engineering, reflecting the high standards of the body-off restoration. These components work in harmony to deliver a raw, visceral driving experience that modern cars cannot replicate. It is a rare opportunity to own a verified, supercharged original.
The Tactile Cabin and Racing Cockpit

The presence of the factory four-speed manual transmission ensures an analog connection to the drivetrain. Every shift is a tactile reminder of why these cars dominate the hearts of enthusiasts worldwide. It feels less like a simple car and more like a high-performance tool.
Rolling Stock and Period Correct Details
