Legend status is matched automatically from the owner's stated specs and the documents on file. It is not an authentication, appraisal, or guarantee.
Published criteria
1969-1970 GTO Judge Ram Air III
1969–1970 · Pontiac GTO Judge · Ram Air III
Matching: full matching · Docs accepted: Build sheet / data card / Certificate (RAIV, marque registry) / Dealer invoice / order form (incl. PHS) / Protect-O-Plate / SPID
The Judge as most were ordered: the 366 hp Ram Air III. Numbers-matching, PHS-documented examples anchor the Judge registry. Collectors have long argued over whether Pontiac used the Ram Air III name officially; the engine behind it is real and well documented, and this criteria set treats the name as settled.
1973-1974 Trans Am Super Duty 455
1973–1974 · Pontiac Trans Am · Super Duty 455
Matching: full matching · Docs accepted: Build sheet / data card / Certificate (RAIV, marque registry) / Dealer invoice / order form (incl. PHS) / Protect-O-Plate / SPID
The last true muscle car: the SD-455 Trans Am, built in tiny numbers while the rest of the industry surrendered. Full matching numbers with PHS documentation.
1961-1966 Pontiac Tri-Power
1961–1966 · Pontiac · Tri-Power
Matching: full matching · Docs accepted: Build sheet / data card / Certificate (RAIV, marque registry) / Dealer invoice / order form (incl. PHS) / Protect-O-Plate / SPID
The engine that started it all: the 389 with three deuces, the original GTO weapon before GM banned multi-carb induction for 1967. Numbers-matching, documentation on file. Widened 2026-09-09 beyond the GTO and beyond the 389: Pontiac sold Tri-Power across the line, so any 1961-1966 Pontiac carrying a numbers-matching, documented Tri-Power engine is in scope here - Bonneville as much as GTO, 421 as much as 389.
1969-1970 Pontiac Ram Air IV
1969–1970 · Pontiac · Ram Air IV
Matching: full matching · Docs accepted: Build sheet / data card / Certificate (RAIV, marque registry) / Dealer invoice / order form (incl. PHS) / Protect-O-Plate / SPID
The apex GTO: the round-port Ram Air IV under Judge trim — 370 underrated horsepower and only a few hundred built per year. Full matching numbers with PHS or RAIV documentation. Ram Air IV in any GTO: rarer than the Judge badge that usually accompanied it. Full matching numbers with documentation. Re-keyed make-wide 2026-09-08 (Legends Field Architecture v2: the engine is the Legend key for US marques) — any 1969-1970 Pontiac with a numbers-matching, documented Ram Air IV qualifies, GTO, Judge, Firebird or Trans Am alike.
Think a criteria set is missing - an option package, a homologation run, a one-year engine? Propose the criteria, not a car. If it is published, every matching car becomes a Legend automatically - including cars whose owners never asked.
