Stonepro Posted February 6, 2021 Share Posted February 6, 2021 Hello, I am considering buying a 2003 Mack CH 600 with E7 engine with 427 HP. I am not familiar with Mack other than I know they are tough vocational trucks. I do know this one is a non EGR engine. 150,000 exam verified miles. Are these engines durable/reliable or high maintenance? Any info greatly appreciated! Quote Link to comment Share on other sites More sharing options...
