That could potentially be a very good deal.
Personally, I would only get an lq motor if it was an lq9, the added compression will help greatly... Especially if you plan on going the l92 top end route (it already hurts the low end because of valve size). Lq4 is more suited for boosted applications.
Also, I would shoot for an 04-06... They have the floating wrist pins/better rods. Just a little bit more added strength.
My build is a 370 (forged motor using stock lq9/4 block and stock crank... I will have a lot more compression than you would be able to make and all the internals are forged (less the crank). However, you could do a similar build with an lq9 with great results using the l92 top end.
I would recommend throwing some Katech rods bolts (they don't need resizing) in just for added safety... It isn't that hard or expensive, no reason not to.
