Including all body types and engine options, Pontiac built over 122,000 units of the GTO from 1969-1971. However, the high-performance GTO ‘The Judge’ model was manufactured in limited volume. The three-year production cycle of ‘The Judge’ saw a recorded 11,004 units being manufactured according to Muscle Cars Illustrated. Pontiac manufactured a total of 6,833 GTO Judge models in 1969 and 3,797 units in 1970, and 374 units in 1971. Among which, 10,711 examples of the GTO Judge were hard tops, and only 293 units were convertible models making them rarer.

In 1971, Pontiac only manufactured 374 GTO Judge models, among which a mere 17 were convertibles. As a result, the 1971 GTO Judge Convertible is the rarest of its kind.

Scouring through listings online, Mecum states only two 1971 Judge Convertibles were finished in Tropical Lime paint, making them the most exclusive.

The GTO Judge came with exclusive decals with tri-color striping on the front fenders, rear quarter panels, and decklid in bright colors giving “The Judge” decal a standout look. A large rear deck spoiler helps distingush it from the standard GTO while being more aerodynamic and visually striking. The interior offered a special ‘The Judge’ emblem on the glove box door.

At the time, the GTO didn’t live up to sales expectations. However, it was positively received by the automotive press and is coveted by collectors today. As intended, the Judge variant of the Pontiac GTO further enhanced the muscle car’s image.

As the automotive industry moved towards stricter emissions standards and the need for engines to run on lower octane, unleaded gasoline by 1971, the Pontiac GTO dropped the Ram Air III and Ram Air IV engines.

In 1971, Pontiac introduced the 455 HO V8 as the standard engine in the GTO ‘The Judge’. The 7.5-liter naturally aspirated V8 produced 335 hp at 4,800 rpm and 480 lb-ft at 3,600 rpm. Pontiac employed a Rochester Quadrajet 4-barrel (750 CFM) carburetor, a high-flow cast iron with dual exhaust, and hydraulic flat tappet camshaft for the OHV engine. The engine ran an 8.4:1 compression ratio and the GTO also used a mechanical fuel pump.

The 1971 GTO Judge used a Muncie M22 Rock Crusher 4-speed manual gearbox, which was the rarest muscle car transmission of its time. Pontiac offered the option of the TH400 3-speed automatic as well. The drivetrain channeled power to the rear wheels with a 12-bolt Pontiac Safe-T-Track (limited-slip) rear end. The standard axle ratios on the GTO Judge included a 3.55:1 (manual) and 3.31:1 (automatic) while 3.90:1 or 4.33:1 gears were available as options.

The GTO Judge models used independent coil springs with unequal-length A-arms at the front, with a 4-link solid rear axle and coil spring suspension at the rear in addition to front and rear sway bars. Furthermore, Pontiac used heavy-duty Delco shock absorbers for the GTO Judge, along with power-assisted 11-inch disc brakes at the front and 9.5-inch drums at the rear. While the muscle car ran on G70-15 Polyglas bias-ply tires as standard, or the optional F60-15 Wide Oval Radials, both using 15-inch Rally II wheels.
