    you can get an aluminum 5.3, the LQ9 out of some of the later Silverados. I think the 6.0 is cast iron, but the latest Escalade motors I think are aluminum now as well(dont hold me to it though)
    Ah so that's what the LQ9 is...I'm still reading up on all the LS differences. Seems like there is a lot of mixing you can do with that motor.

    Just did a lil research...compliments of LS1.com.

    The LS series is expansive ranging from 4.8 to 7.0 in steel and aluminum. The crank on all LS engines save for the 4.8 and 7.0 are the same 92mm (3.62). And if I am not mistaken all LS series also have aluminum heads.

    Heres some LS info for ya.

    The LQ is the workhorse motor in the family for sure... Plenty stout, durable and it can be stroked out as well. Lots of 1xxxx power LQ combo lurking in everything from Vettes to Tahoes to Trailblazers to RX7's out there.
    We stay swingin...
