Two model years. That's all the Pontiac G8 GT ever got — a Holden Commodore built in Elizabeth, South Australia, with an all-aluminum L76 making 361 horsepower. The Charger R/T never offered a manual. The GXP did: LS3, 415 horsepower, Tremec TR6060. Send it to the Mopar guy. #ThreePieceUS #PontiacG8 #G8GXP #ChargerRT #HoldenCommodore #ChevroletSS #LS3 #V8sedan #slepton #cars #wheels
