nelm1994 Posted April 13, 2017 Share Posted April 13, 2017 What e7 ? I have a 2006 granite with an ai 460 . If you like no power and poor mpgs this is the engine for you. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/49522-2007-mack-granite-with-e7-any-thoughts/#findComment-367197 Share on other sites More sharing options...
Mackpro Posted April 19, 2017 Share Posted April 19, 2017 Better have 4.42 or 4.64 rears and the engine needs to be a AMI370 , AI427 or AI460 before I would even look at it. . Performance even at 460 HP is OK but not great I guess. As far as MPG . 5.3 average is the best I have ever seen but 4.3 to 4.9 is what I see most. Most of my friends are slowly upgrading to GU MP-8's in the last couple of years and are very happy. Amazing what a 100 extra cubic inches does. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/49522-2007-mack-granite-with-e7-any-thoughts/#findComment-367818 Share on other sites More sharing options...
nelm1994 Posted April 19, 2017 Share Posted April 19, 2017 Mark pro is right on the mpgs I was getting low 4s before I upgraded to stage 2 injectors, bigger turbo, area diesel module and 5 inch exhaust . Now I get high 5s . Power is a lot better but I was expecting more from a 460.
