i'm going to look at a motor that is supposed to be a lq4 once i get there how do i make sure its a lq4? its a long block if that makes it easier

The block should be made of iron, with '6.0' cast into it at the back (don't remember which side). Pull a spark plug (or head, if you're ambitious), & look at the pistons. If they have a bit of a dish to them, you're looking at an LQ4 - if they're flat-tops, it's an LQ9. Good luck.

(OK, here's where I get to see if my understanding of all this is way off-base...)

yes, the lq4 is iron block, will most likely have "317" heads on it - the piston information mentioned above is correct...and yes, "6.0" is cast on the back of the block.
