hello everyone, I'm new here, and to the trucking world! I've just got my class one here in bc, and i'm looking to buy into a used dump truck. I'm hoping to stay away from electronically controlled engines, but am unsure what years are involved. I'm looking at an add fora 1998 mack cx613 with an e7 427 engine. is this mechanical or electronically injected? It has a 13 sp trans (i'm assuming mack?). Does this year truck have any inherent flaws or problems i should be aware of? How is the fuel efficiency of this engine? is 427 the horsepower rating? If it is electronic injection, is it reliable, or should i look for mechanical pump, and if so, how new of truck can i look at that is still mechanical? sorry if all this sounds like newbie stuff, but i'm looking foward to getting my feet wet in the gravel hauling world! thanks all!
