My name is Richard from western NSW , Australia. I have a '86 Superliner ( originally from Sherwin Cattle co ) with a E9 500, 12 speed, 4.64s 44s and a 90 Valueliner E6 350, 12 speed , 4.64 44s. Both used for road train work and low loader work. Love the old macks, I do all my own repairs and maintainence. They handle the harsh environment easily with the correct Mack upkeep. My 6 year old son loves coming with dad and already thinks he can handle a 12 speed, given the opportunity to . We grow grain so it's mainly tipper work, however we did a lot of heavy and oversize concrete work for years. I drove in USA for 10 months in '99 which was awesome , worked real hard , partied harder in them days, ha ha. I love reading all the v8 talk , they are solid engines, if you haven't driven one, you simply don't understand . Cheers from Australia , Richard
