Restored, Matching-Numbers Corvette Roadster L72 427/425 V8 Muncie M21 4-Speed

Among vintage Corvettes, few configurations are more sought-after than a second-generation roadster with the legendary 427/425hp L72 big block. Known for its raw power, unmistakable sound, and limited production numbers, the L72 remains a benchmark for collectors. Values continue to trend upward, and finding an example this well-restored (with its factory powertrain intact) is increasingly rare.

This 1966 Corvette Sting Ray is a numbers-matching L72/4-speed car that checks all the right boxes. Finished in its correct 984AA Sunfire Yellow over black, it underwent a thorough, three-year restoration that emphasized factory-correct components, show-level cosmetics, and mechanical reliability. Built with a no-nonsense performance mindset, this car was ordered new without a radio or heater…luxuries intentionally omitted in favor of performance and minimal distraction.

The body started as a straight, damage-free shell. It was stripped and professionally refinished well beyond factory standards before being sealed in smooth two-stage Sunfire Yellow with a glossy clearcoat. The panel fit is tight, and the lines are crisp throughout. Chrome and stainless trim have been fully restored or replaced. A black top, functional stainless side pipes, and turbine-style wheels with chrome spinners give the car a clean, aggressive stance.

Under the hood, the matching-numbers 427/425hp L72 V8 remains intact, verified by its 3869942 casting number, correct “IP” suffix, and partial VIN stamp. It's been rebuilt and correctly detailed…from the chrome air cleaner and Winter aluminum intake to the factory-style manifolds and reproduction tower clamps. Ancillary items like the Delco battery, radiator, ignition module, and fuel lines are all either NOS or correctly restored. The engine bay presents exceptionally well and is fully functional, built to show and drive.

Backing the big block is the original Muncie M21 4-speed transmission with NOS internals, paired to a correctly rebuilt 3.70:1 posi-traction rear end. The fully sorted chassis features a stock-style double A-arm front and independent rear suspension, correct springs, fresh shocks, and power four-wheel disc brakes. Everything underneath has been cleaned, detailed, and reassembled with precision. The satin black frame, properly finished floor pans, and vivid inspection marks all speak to the level of workmanship.

Inside, the car retains its correct black vinyl interior, which was completely replaced during the restoration. Seating is firm and supportive, with fresh seatbelts, chrome trim, and a restored shifter. Gauges are clear and functional, with a center-mount clock and aluminum-trimmed glovebox. New carpet, sill plates, and stainless-trimmed door panels give the cabin a clean, period-correct feel. A satin-spoke steering wheel with a cross-flag horn button ties everything together. Even the rear cargo area is fully carpeted and clean.

From its matching-numbers drivetrain to its high-quality finish and performance-focused pedigree, this L72 Corvette is a standout example of one of Chevrolet's most iconic offerings. With C2 values holding strong, it represents an excellent opportunity to acquire a true big-block investment car that lives up to the legend.
