made available on Charger 770 and Charger R/T. E38 was a race-ready Charger R/T with the additional A84 Track Pack option, which included a fuel tank. There was also an A87 Track Pack option that included all the race track goodies, but for the larger fuel tank. In mid-1972, the E38 option was superseded by the more powerful and greatly refined four-speed transmission E49 option. This drew comments from Wheels such as, "The raw quivering power is instantaneously on tap and with a ratio for every conceivable situation the Charger just storms through. It would take a Ferrari Daytona with racing driver Jackie Ickx at the wheel to stay with one". All E49s came with a Track Pack, 21 of which featured the huge fuel tank with dual fillers. The E49 six pack engine came with a baffled sump, tuned length headers, special shot-peened crankshaft, connecting rods, pistons, rings, cam, valve springs, a twin plate clutch and of course the triple 45 mm dual throat Weber carburetors. Chrysler quoted this engine as producing which, in a car, made for rapid acceleration. The R/T E49 was the ultimate Valiant Charger, and with only 149 built the E49s are still widely considered today as one of the greatest Australian "muscle" cars ever produced. Road tests of the era recorded quarter-mile times of between 14.1 and 14.5 seconds. 0 to in 14.1 seconds was the norm. This compares to times of 14.6 for the next quickest accelerating Australian muscle car, the Ford XY Falcon GT-HO (Phase III). Although the Six Pack Chargers were the dominant performance players in the VH range, there was another Charger, the , V8 powered E55, that came close. Option E55 was applied to the new Charger 770 SE in August 1972, and this car could reach in 7.2 seconds and complete the quarter-mile in 15.5 seconds – all topped off by a top speed of . A batch of several hundred VH Charger 770 318 V8s were exported to Japan along with CH sedans. The Chargers had a CH-like nose with VH sheet metal surrounding the CH four headlights and grille, a combination that NZ assembler Todd Motors would later use to create its unique VJ Valiant Regal 770 sedan. The Japanese cars also had air conditioning, side marker lights and separate white reversing lights as well as mirrors conforming to Japanese market regulations.
