Go package

During the late-1960s and early-1970s, domestic automakers lines used "catchy marketing campaigns, such as Dodge's "Scat Pack", Plymouth's "Rapid Transit System", Ford's "Total Performance", or Oldsmobile's "4-4-2" and "W-machines".

[10] In contrast with high-performance versions – such as the 1969 Hurst SC/Rambler, 1970 Rebel Machine, and 1971 Hornet SC/360 – that had a specific model numbers assigned to them, only an original window sticker (Monroney sticker, factory order form, or a build sheet can authenticate whether a particular vehicle was originally factory equipped with a Go Pack because there is no identification code within the vehicle identification number (VIN) or on AMC's metal door tags to identify this option.

The Go Pack on the 1968 AMX included either the 343 cu in (5.6 L) or 390 cu in (6.4 L) high-output four-barrel V8 engine with a dual exhaust system with chromed exhaust tips, heavy-duty cooling system, power front disc brakes, uprated suspension for improved handling, "Twin-Grip" limited-slip differential, wide-tread red striped tires mounted on five-spoke "Magnum 500" wheels, and over-the-top racing stripes.

[2] In addition to the Hornet SC/360's standard features such as floor-mounted transmission shifter, individual reclining seats, rally stripes, slot-style wheels, and D70x14 performance tires, the Go Package substituted or added the four-barrel 360 cu in (5.9 L) V8 rated at 285 hp (213 kW; 289 PS), ram-air hood scoop, dual exhaust system, handling package, white-lettered tires, and a tachometer.

It included either a 360 cu in (5.9 L) or 401 cu in (6.6 L) high-output four-barrel V8 with cowl air to carburetor induction system, and dual exhausts, "Twin-Grip" differential, handling package, power disk brakes, heavy-duty cooling, a "T-stripe" on the hood, blacked out rear taillight panel, "Rally-Pac" instrumentation, E60x15 raised while letter Goodyear Polyglas tires on 15x7-inch slot-styled styled steel wheels, and a "space-saver" spare tire.
