    lc9 dod delete, question about oil pump

    Im gathering parts for dod delete on my lc9 5.3, I was gonna order a new ls1 oil pump since it wouldnt need the high volume any more, but I was reading over on ls1tech that I can just change out the spring on my high volume pump. Any body know anything about this?

    if i could do it again id for sure change the LC9 pump out. my oil pressure is lower then non DOD motors run at
    for that amount of money its worth the piece of mind to change it out IMHO

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference

    That's odd. When we swap out the dod stuff with non dod hardware oil pressure increases to around 40psi at idle; if I remember correctly.

    Farmtruc, so you just leave the same oil pump on these dod engines? So far I have set of ls7 lifters, 206/212 gen 3 cam (free, couldnt pass it up) 4.8 ly2 valley cover, 3 bolt 4x cam sprocket, new crank pully bolt and 4 regular lifter trays. Am I missing anything?

    Yes you can keep the stock oil pump and pressure will increase.

    You can run stock pump but from my experience my oil pressure is lower then I'm used to...30psi when warm
    70k on truck and almost 7000 worth of non-dod miles.
    Its 45 cold
    30 warm
    45-50 wot
    Very hoy days 20-25

    This truck has always had lower psi from day I bought it and figured once DoD was gone it would rise up... Not the case
