Junkyard engine guys
The 6.0 I bought had 110k on it.. I only bought it for the block, crank and heads ( i put forged rods and pistons in) Upon taking it apart the bearings were like brand new, motor was spotless inside. I should have just boosted it

all of ours are 160+ K at least and they are ******* GEM's they work great.
every now and then we fire em and they have lifter noise from sitting in the yard without oil for a long time, but a few 7k rev limiter bangs later they quiet up from then on and are nice and quiet after that.
we've had really ugly motors make 600rwhp through automatics

Maybe Im thinking too much into this decision but which would you guys go for, a 2006 LQ9 with 167k on it or a 2003 LQ9 with 117k....same price. Thats what im faced with right now. I know the 06 would have the better rods and its obviously a newer motor but with 50K more miles.

Hmmmm that is tough. Buy the newer one and pull the heads off when you get home, check for cross hatching still nice and shiny. Idk if I'd pull the pan and caps, I've never seen one that looked rough unless it had the **** kicked out of it.

yeah that is a tough one for sure. I myself like the idea of the better rods. Dont know of any other advantages. Someone else may know of some that the 06 has. Maybe pull a valve cover on each one and judge by the condition inside it. Maybe the one with higher mileage is cleaner inside and therefore you would think had more regular oil changes or better oil was used???? SOmetimes you can judge the better engine by the amount of crud buildup in the valve covers. You should be able to tell the difference between and engine that had 10000 mile intervals and one that had 25000 mile intervals. Know what i mean?
