    We have a 4500 crew cab, Dmax/Allison that was assembled the week of 24 May! It is now on engineering hold but we do expect in the pacific north west in the next couple weeks!
    The Qs are regarding the Duramax.

    1/ will it have the revised (e.g. injectors outside the rocker covers) heads?
    2/ Will it have the variable pitch turbo?
    What other internal changes were there to the revised engine?
    3/ will if have an EGR? (being a non CA over 8500 GVW vehicle)
    4/ Will it have some sort of soot &/or catalytic device?
    5/ what will the rated horsepower be? & at what RPM?
    6/ What will the rated torque be? and at what RPM?
    R.S.V.P.

    I have not received the medium-duty media package yet, but we know that the LLY went into production late last fall. I doubt the LB7 would have continued once the engine production converted to the LLY.

    The medium-duty trucks operate under a somewhat less stringent emissions specification, which will impact the emissions package.

    There'll be more medium-duty coverage once the info arrives.
