    No.......but I know the engine isn't getting oil.
    I just have never heard a piston slap personally but I HAVE heard rods knocking.

    That just sounded too loud to be anything other than a rod knocking to me.....but I know
    Knuckle Dragger said they do kinda sound similar so I'm going to start with the oil pump.

    it's the cheaper of the 2. Besides, another local LS1 engine shop said most likely
    the oil pump lost it's prime, and might need to be removed and packed with assembly oil.
    My shop said they've NEVER used assembly oil because it's so thick, and every engine they
    put a new pump in worked fine on the first startup without it.....
    It's 4 hours of labor @ $75 an hour.......so $300 in labor....which sucks ass.
    So there's no point in wasting the time just to put the old one back in there......
    I'm spending the $170 for the SLP one and I'm going to cross my fingers because if this fails
    I'm seriously going to be upset,

    So I'm kinda stuck here ........going to try the $500 option first.....

    Dumb question.

    I heard the knock, then I heard it smooth out. Was that your car, or was that something in the background?

    IMHO an oil pump will not fix that problem. The damage is already done hence the knocking or a spun bearing.

    If you want a peace of mind while revving the poo out of that thing, find a shop to rebuild it or search on LS1tech for shops around you that can help.

    That sound reminds me of my first SBC which had an oiling issue...low pressure. It sounded like that while I was on the interstate. next thing I know I was on the roadside with the engine smoking like cheech
