Whats your impression of a 5.3L LS motor in these trucks?

[StingRay]

I just picked up a whole truck with with an LQ4 that has 75K on it for 2200 Canadian. I will get all of that back in parting the rest out. I also grabbed another LQ4 complete with all accessories, harness and computer for 650 Canadian. It's going into my buddies Camaro right now. I can buy a 5.3 with all of the stuff at my local wrecker for 450 bucks all day long. They can't sell them. When a truck comes in they check to see if the tranny works well and nothing else. They are literally scrapping the 5.3's and the 4.8's.
