  1. As with the VIN, the cowl tag does not
    verify GTO status until 1966 when the Style
    Line adopted the same 242 prefix as the
    VIN. That said, in some cases, secondary
    cowl tag codes can signal GTO-only details.
    Here, the hastily scribbled grease-pencil
    markings—which were often scribbled by
    inebriated workers toiling in mind-numbing
    obscurity—read “vinyl” and “N13.”

  2. VIN and cowl tags be damned, this time
    a worn die-cast emblem speaks to us and is
    all we need to accept this example as a true
    GTO. It’s placed just right and clearly hasn’t
    been messed with since 1965.

  1. The VIN plate and cowl tag of this four-
    speed pillar coupe (dig the clutch pedal
    and floor-shift hump) were missing, so
    we couldn’t verify the year. Inside, the
    ghost of the triangular GTO emblem
    above the glovebox suggests it’s a 1964
    model, making it one of the 7,384 Sports
    Coupe GTOs built. Our research says 1965
    used a rectangular-shaped emblem in
    this location. The twin circles punched
    into the ends of the dash panel once
    held A/C vents. Non-A/C GTOs lack these
    large holes.

  2. Just down the row from its hardtop
    cousin, we spotted this pillar coupe
    (Pontiac called it a Sports Coupe). The
    least popular model (according to sales
    totals), the bright-metal trim covers a rigid
    B-pillar. Likewise, the doors (not shown)
    have full window frames. These features
    reduce the open-air feeling and outward
    visibility compared to the pillar-less
    hardtop.

  1. This under-construction image from
    the Motor Trend Archives depicts the
    Dickinson, TX–based Gay Pontiac altered-
    wheelbase GTO match-bash racer of 1966.
    Note how the wheelbase-relocation work
    took place on the body (stretched wheel
    openings) and on the framerail (axle
    and mounting points moved forward 10
    inches). With a supercharged 421 Super
    Duty on nitro, this machine ran 9s at
    150+ mph. Either one of the GTO hulks
    here would make a great starting point!


GROOVY FACTOIDS



  • In 1965, Pontiac GTO sales materi-
    als read “Have new tigers. Need
    tamer. Apply at any Pontiac dealer.”
    Truth be told, GTO engines were
    pretty mild compared to Pontiac’s
    aborted 1963 Super Duty program.
    If GM hadn’t ordered its divisions to
    quit blatant race engineering and
    competition in March 1963, it is
    likely real animals, like 421 SD GTOs
    with aluminum fenders might have
    become reality. But Pontiac did the
    best it could under the existing gov-
    ernment anti-trust scrutiny, selling
    more sizzle than steak.

    • The 1965 GTO continued the dual-
      exhaust system that helped make the
      1964 GTO a success, but the “cold-
      side” muffler (right hand, as seen
      from driver seat) was upgraded with
      stainless-steel heads and shell. The
      aluminized steel shell and heads used
      in 1964 were more prone to corrosion
      from acidic exhaust gases on the
      right-hand tract. The left-hand tract
      ran hotter, thanks to how the GTO’s
      exhaust cross-over system put more
      heat into the spent gases exiting
      from the driver-side tailpipe and tract.
      The hotter gases canceled much of
      the acidic corrosion.





  1. The clutch pedal
    and floor hump
    make this one a
    stick-shifted fun
    machine. The GTO’s
    automatic offering
    for 1965 was based
    on Buick’s two-
    speed Super Turbine
    300—no fun. But
    just because we
    see a floor shift and
    clutch pedal doesn’t
    guarantee a Muncie
    four-speed once
    lived beneath the
    tunnel.

  1. This intriguing paint-stamped firewall
    message reads, “line test ok second shift.”
    We don’t know the specific meaning, but
    have never seen it on another GTO. It could
    be a paint-quality audit or something to do
    with the speed setting of the assembly-line
    trolleys from one work station to the next.
    Before blindly copying markings like this to
    other GTO restorations, it’d be wise to contact
    an outfit like Jim Mattison’s Pontiac Historical
    Services for clarification.

Better yet, the GTOs on display
exemplify two of the three available
body types offered in 1965. One is a
hardtop coupe, as were 55,722 of the
75,352-car total. The other is a pillared
sport coupe, just one of 8,319 made.
The only body configuration missing
was an open-roof convertible, of which
11,311 were built, but nobody seems to
throw away. Let’s wander through the
auto ranch and snoop out some Goats!
