AMX, I'm still not totally well-versed on Oz Chargers but the hottest factory engines were the 265 cubic inch inline six cylinder Hemis with the three Weber two-barrels. These were called the Hemi Six-Packs. The top dog versions of these put out 302 horsepower and could run very low 14 second 1/4 miles. A good number of Oz Chargers were 318 and 340 equipped. The 340's, however, were detuned versions of the American 340's. I'm sure ol' OzHemi can be of major assistance in helping you find an Oz Charger. Also, you can check out the following website which is an Australian Mopar online classifieds site. I think they also have a message board.
