Correct Xlr8n. Sorry, I was probably off on my years. 99-00 sounds right.

This may not be 100% true. At some point LQ9's got beefier rods. And later on in 2005 LQ4's started getting the same beefier rods. These rods are supposed to be the same ones that come in the LS2.
what kind of vechiles can I find the low compression LQ4's with the beefier rods in? I'm tossing around the idea of doing a rear mount.

Pretty sure that LQ9 always had the LS2 style rods with full floating pistons and coated skirts. Midyear '04 LQ4s got the same rods and full floating pistons and coatings. From MY04 up the only diff between the two is flat top pistons vs dished.
And any LQ4 in an '05 or newer will be the newer setup. Vans, trucks, SUVs, h2, doesn't matter.
