  1. Agree, you are right re mpg and running rich. And I am right cause as stated it would never survive SD durability standards. Same reason gm didn't drop the 6.2L into the hd when it made more # than the old 6.0L. Wouldn't have survived the stress. (Plus rated on premium)  instead they designed new 6.6L.

    7.3L 538 lbs

    Coyote 404 lbs

    Diff 134 lbs. 

     

    Now the good news is the 7.3L is much more compact vs the 5.0L. 

     

    Ford didn't spend all that money going aluminum to save 750 lbs on a F150 crew just to throw in a iron block. But who knows... all speculation. The last iron block in a half ton? MY2014 F150 w 6.2L which outside Raptor was max 5% of sales?

    Sounds about right !  I still think it is odd that the E-Series has a de-tuned version.

    6.8L would be a great base engine for a F250 and a low cost replacement for the Coyote in the F150.

    But would they make a 6.8L with iron and aluminum block. Not likely. And unlike the 6.2L which lived in F150 and SD for 4 year overlap I don't think they will put an iron block in a F150 today. Too heavy. And aluminum block in a SD would melt like butter in Az summer.  Would never handle the tougher SD durability testing. Same reason no EB in a SD or a 6.2L gm in a gm HD.
