[lts70]

Not trying to high jack, if I am let me know and I will post a new thread.
I found a LQ9 in my local classifieds and was wondering what you guys think. I called the guy and he believes it came out of a 03 Gmc that had around 60,000 miles. No Computer with it. He did not know what trany it was just said it was a 5 speed auto.

Here Is his Add.

"Vortec 6.0 Liter LQ9 w/ auto tranny $400. I bought this engine/tranny from a dude who wrecked his truck. I was going to put it into my FJ40, but i ended up putting a different engine in it.This engine is disassembled, but i have all the parts from when i took it apart. Probably needs a rebuild kit. To be honest, I don't have the time or know-how to get it up and going, so this could be a real steal if you're into this sort of thing."
