    Pontiac GTO / Tempest / LeMans — Option Codes

    Covers the A-body Tempest/LeMans line (1961–1981 context) and the GTO (option package 1964–65 and 1972–73; own series 1966–71; Ventura-based option 1974). Through 1968 Pontiac documented options with 3-digit sales codes; from 1969 order documentation used corporate UPC/RPO codes (WT1, L74…), with numeric sales codes persisting on invoices. 1964–67 cowl tags from some Fisher plants additionally carry five-group accessory codes (digit + letter, e.g. 3F) that are body-plant codes, not order codes.

    Years 1961–1963

    First-generation "rope-drive" Tempest (195 4-cyl, 215 aluminum V8, 326 V8 in ’63). No comprehensive machine-readable option-code list was located in web sources — a coverage gap. Options were ordered by Pontiac numeric sales code; PHS documentation is the reliable per-car reference for these years.

    Year 1964

    Code Description Years Models/Notes Confidence
    382 GTO option package — 389 4-bbl (325 hp), HD 3-speed floor shift, dual exhaust, hood scoops, badges 1964 Tempest LeMans (coupe, hardtop, convertible); $295.90 confirmed
    — 389 Tri-Power, 348 hp 1964 GTO engine option; sales code not confirmed in sources confirmed (engine), code gap

    1964–67 accessory sales codes at Fisher plants FRA/KAN/PON were also stamped as grouped codes on the body tag (groups 1–5: e.g. group 1 power top/tinted glass/two-tone; group 2 trans/AC/console; group 4/5 mirror & décor groups) — see gtoforum reference thread in Sources.

    Year 1966

    GTO became its own series (VIN series 42), so the GTO itself no longer carried an option code. Option prices below are from the 1966 mid-size fact sheet (codes not printed in that source).

    Ram Air chronology (ordering-code summary)

    • 1965–66 "fresh air" / XS (1966): first Ram Air setups; 1966 XS engine (Tri-Power, 360 hp) — XS is an engine block code; the package was largely dealer-installed. — confirmed
    • 1967 Ram Air (I): GTO & Firebird 400 Ram Air; sales-code ordering (Firebird ’68 analog: 347). — confirmed option, GTO code gap
    • 1968 Ram Air I → Ram Air II (mid-year, 366 hp). — confirmed
    • 1969–70 Ram Air III = L74, Ram Air IV = L67 (GTO). On the 1970 Firebird, RA III = L74, RA IV = LS1 (SPO special order). — confirmed
