The 1967 Shelby GT500 is one of the most iconic muscle cars ever built, known for its aggressive styling, powerful 428 cubic-inch V8 engine, and historical significance. Owning such a classic requires diligent maintenance to ensure its performance, authenticity, and value remain intact. Whether you drive your GT500 regularly or keep it as a collector’s item, following a structured maintenance routine is crucial. At Revology Cars, we understand the importance of preserving classic cars, and this guide will walk you through the best ways to maintain your 1967 Shelby GT500.
Routine Maintenance Essentials
Engine Care
Regular oil changes should be performed every 3,000 miles or at least twice a year using high-quality conventional or synthetic oil. The air filters must be checked and replaced as needed to ensure optimal airflow and engine performance. Coolant levels should be monitored, and the radiator should be flushed periodically to prevent overheating. Spark plugs require routine inspection and replacement to maintain ignition efficiency.
Transmission & Drivetrain
Transmission fluid should be changed as per the recommended schedule to prevent gear wear. The clutch system, for manual models, should be inspected and adjusted or replaced if necessary. The rear differential must be maintained by checking fluid levels and replacing them when required.
Braking System
Brake pads and rotors should be checked for wear and replaced when needed. Brake fluid must be flushed and replaced periodically to maintain stopping power and prevent corrosion in the system.
Suspension & Chassis Maintenance
The suspension system should be inspected for worn-out bushings and replaced when necessary. Shocks and struts should be checked for leaks and deterioration. Wheel alignments and tire rotations must be performed regularly to ensure even wear and handling stability.
Electrical System Maintenance
The battery should be tested and maintained, ensuring terminals are corrosion-free. Wiring harnesses and connections should be inspected for signs of aging or wear. The ignition system must function properly, and upgrades should be considered while maintaining authenticity.
Exterior & Interior Preservation
Paint & Bodywork
Regular washing and waxing should be done to protect the paint from oxidation. Rust and corrosion should be addressed immediately to prevent long-term damage. A car cover should be used when the vehicle is not in use to shield it from dust and environmental factors.
Interior Care
Leather seats must be cleaned and conditioned to prevent cracking. The dashboard and instrument panel should be maintained by avoiding prolonged sun exposure. Gauges and switches should be checked to ensure they function correctly.
Fuel System Maintenance
Fuel filters should be replaced regularly to prevent clogging and ensure proper fuel flow. The fuel pump must be checked for proper operation to avoid engine performance issues. Fuel injectors should be cleaned periodically to maintain optimal combustion and efficiency. It’s essential to use fuel stabilizers if the engine will be stored for an extended period. Additionally, checking for rust or corrosion in the fuel tank can help prevent contamination of the fuel system.
Seasonal & Long-Term Storage Tips
If storing the vehicle for winter, fuel should be drained or stabilized to prevent degradation. The car should be placed on jack stands to prevent tire flat spots. Exhaust tips should be covered to prevent moisture and rodents from entering.
Performance Tuning & Authenticity Preservation
Original parts should be retained whenever possible to maintain the car’s value. Reversible upgrades should be chosen to enhance reliability without compromising authenticity. Owners should register their Shelby GT500 with Revology Cars for historical documentation and preservation guidance.
