Seed file — full Archetype C buildout deferred to Phase 1.
Shelby American is the producer of the original Shelby Cobra (1962–1967) and the continuation series that began with the CSX4000-series 427 Cobras in 1997. Today’s Shelby American continuation lineup includes the CSX6000 (427 S/C), CSX7000 (289 FIA), and CSX8000 (289 Street). Continuation cars are sold as rolling chassis without engine and transmission; dealers install the running gear at customer specification. Shelby American is the only entity authorized to use original-format Shelby chassis numbering on new cars.
Founding and history
Carroll Shelby’s background, the founding of Shelby American in Venice, California, the AC Cars partnership, and the 1962–1967 original program are to be filled in during Phase 1 from cited sources. See also knowledge/cobra-encyclopedia.md.
Chassis prefix conventions
This is the most important reference point for any build article on an original Shelby Cobra or a Shelby American continuation car. Each prefix has its own chassis-family page under knowledge/chassis-families/ once those are built.
Original-era prefixes (1962–1967):
- CSX — leaded-frame 260/289 cars (CSX2000–CSX2602)
- CSX2 — later 289 cars (MkII era, rack-and-pinion steering)
- CSX3 — 427 / 428 big-block cars (CSX3001–CSX3360). The "427 Cobras."
- COB / COX — AC Cars’ own chassis numbering for AC-built cars destined for markets other than the US
Continuation-series prefixes (1997–present):
- CSX4000 — continuation series 427 Cobras, started 1997
- CSX6000 — current production. 427 S/C Cobra
- CSX7000 — current production. 289 FIA Cobra
- CSX8000 — current production. 289 Street Cobra
Continuation program
Shelby American restarted Cobra production in 1997 with the CSX4000-series 427 Cobras. The continuation program is distinct from the licensed replica industry (Superformance) and the unlicensed replica industry (Kirkham, Backdraft, ERA, etc.) — Shelby American is the only entity authorized to put original-format Shelby chassis numbering on new cars. Continuation cars are sold as rolling chassis without drivetrain to comply with US new-car regulations; dealers install the engine and transmission to customer specification.
