LQ9 Carnage Pics! Last night I pulled the motor out of my caddy hoping to do a ring job and put it back together... THIS is not the case 
now my question is what is the most cost effect replacment for the pistons?
on a tight budget but am open to all idea's if its enough benifit!
...also, since I'm replacing the pistons would it work to run a dished piston with the stage 2.5 5.3l (milled to 58cc) heads I have that are fully built with a 212/218-ish comp cam on 114 lsa?
where do i go from here?
6 of 8 pistons have major chunks burnt away (i'm guessing this was a tuning problem?)
someone stole my engine!?!?!?

I've heard of these pistons breaking ring lands but to have 6 of 8 broken, make sure you check everything in the tune and fuel delivery when you fix it. How do the bores look? I would think you have some scoring. I would have the bores checked and measured even if there is no obvious damage. Are those stock pistons? That thing must have been using some serious oil.

I would find another low milage LQ9 in a good salvage yard.
I bet there is a little more damage else were in the motor. Like cylinders, bottom of heads or even worse a cracked block. Look everything over very well.

stock 10:1 flat top pistons
I seriously think the previous owner didnt tune it after installing the blower,
yeah it barely ran
I'll be having the heads checked out since they look NASSSSTY....
