fjh Posted 21 hours ago Share Posted 21 hours ago Minimal! If you have an e6 4 valve the mounting is identical! 1 Quote Link to comment https://www.bigmacktrucks.com/topic/76466-is-there-a-physical-size-difference-between-e6-and-e7-engine/#findComment-592673 Share on other sites More sharing options...

Popular Post fjh Posted 5 hours ago Popular Post Share Posted 5 hours ago On the four Valve in true Mack fashion they started transitioning the engine to E7 block by practicing with the e6 changing the front cover to aluminum and adding a front mount that had pads instead of the trunnion mount set up! there were other subtle changes but that was the most noticeable! That dimensions are the same mount to mount ! Joey I Can't imagine you embellishing anything😅 Simply stating what you believe to be true just like the rest of us!🙏 3 Quote Link to comment https://www.bigmacktrucks.com/topic/76466-is-there-a-physical-size-difference-between-e6-and-e7-engine/#findComment-592698 Share on other sites More sharing options...
Freightrain Posted 1 hour ago Share Posted 1 hour ago I was at Buddy's house that is helping with my motor. He has 5 new rods for an E7. They are huge compared to an E6. I asked him what was different between motors. They are basically the same overall, but the front mount area is upgraded. He is contemplating building an E7 for his pulling truck and not tell anyone that it isn't a 237. 😆 1 Quote Larry 1959 B61 Liv'n Large......................
