j hancock Posted July 29, 2019 Share Posted July 29, 2019 It is a Mack diesel (E), turbocharged (T), series aftercooler (S), emissions level (Z), Dynatard engine brake (B). As the tag shows, it is a 350 HP based on the 672 displacement block. 1 1 Quote JimIt doesn't cost anything to pay attention.

JoeH Posted July 30, 2019 Share Posted July 30, 2019 Same block as the older endt676 engines and the E6 motors. (Might b minor block changes over the years) 1 Quote Link to comment https://www.bigmacktrucks.com/topic/58346-mack-engine-id-help/#findComment-429005 Share on other sites More sharing options...
