bulldog man Posted October 24, 2007 Share Posted October 24, 2007 To best i can remember : Econodyne was basically the "fuel pincher" or fuel effcient version of the Mack motors Maybe FJH , superdog , HK or Barry could chime in & know something i dont later yall Quote You Cant Fix Stupid.

Lmackattack Posted October 24, 2007 Share Posted October 24, 2007 I belive the econodynes had higher HP outputs but lower TQ rateings. they needed more gears to pull you as the power band was up top and not as wide as the maxidynes. I think they came in low rpm models and standard 2100 versions and they claim that they were better on fuel.?trentdsf Quote Link to comment https://www.bigmacktrucks.com/topic/2992-econodyne/#findComment-14681 Share on other sites More sharing options...
